ITEM 1.   BUSINESS

     For a discussion of certain material factors which may affect the Company,
see "Cautionary Statements and Risk Factors" commencing on page 11 of this
Report.

GENERAL

     3D Systems Corporation (the "Company") develops, manufactures and markets
worldwide solid imaging systems designed to rapidly produce physical objects
from the digital output of solid or surface data from computer aided design and
manufacturing ("CAD/CAM") and related computer systems.  The Company's systems
include SLA Industrial Systems ("SLA") and Solid Object Printers.  As part of
the SLA systems, the Company provides consumable materials as the exclusive
worldwide distributor (except for Japan) of stereolithography photopolymer
resins ("resins") produced by Ciba Specialty Chemicals, Inc. and its affiliated
companies (collectively "CSC" or Ciba Specialty Chemicals).  The Company's solid
object printers use proprietary materials developed and manufactured by the
Company or its toll providers.  The Company either directly or through its
network of authorized distributors provides a majority of its customers with a
variety of on site maintenance services.  

     SLA Industrial Systems use the Company's proprietary stereolithography
technology, a solid imaging process which uses a laser beam to expose and
solidify successive layers of photosensitive resin until the desired object is
formed to precise specifications in hard plastic.  SLA-produced parts can be
used for concept models, engineering prototypes, patterns and masters for molds
and other applications.  This technology can provide users with significant time
savings, cost reductions and improved quality, compared to traditional modeling,
tooling and pattern-making techniques.

     Solid Object Printing employs hot melt ink jetting technology to build
models in successive layers using a proprietary thermopolymer material and are
sold as the Actua 2100  and the ThermoJet Solid Object Printer.  These printers,
the size of an office copier, are designed for operation in engineering and
design office environments.  Designers, engineers, and other users of CAD/CAM
systems can incorporate these printers into their office networks as a shared
resource, to rapidly produce models of products under development.  

     Solid imaging is a relatively new field embodying the use of computers and
computer automated equipment to rapidly produce prototypes, models and even low
volume production quantities of objects which traditionally have been produced
by machining and other methods.  The Company believes that the stereolithography
technology, which it has developed and patented, represents the first and to
date the most significant development in this field.  While alternative
technologies exist and while it has been reported that significant research and
development efforts are currently being undertaken by corporations and
universities around the world in an attempt to develop additional alternative
technologies and techniques, on the basis of total systems installed, the
Company believes that it currently remains the leader in the solid imaging
field.

     The Company markets directly and through secondary distribution channels 
to customers in the United States and Europe and through distributors in 
other countries.  The Company sold its first SLA system in 1988 and its first 
solid object printer in the fourth quarter of 1996.   As of December 31, 
1998, the Company had sold a total of 1,243 solid imaging systems to 
customers in over 40 countries. Its customers include major corporations in a 
broad range of industries including manufacturers of automotive, aerospace, 
computer, electronic, consumer and medical products.  The Company also sells 
SLA systems to independent service bureaus which, for a fee, provide 
stereolithographic services to their customers.

     As of December 31, 1998, the Company held approximately 160 patents related
to solid imaging: 75 U.S.;  49 European; 6 Japanese; and 30 other foreign
patents.  The Company continues to develop improvements for its lines of
products as well as new products to expand the applications of solid imaging. 
In conjunction with CSC, the Company continues to develop resins with different
and improved characteristics to expand stereolithography applications.  CSC is a
Swiss-based multinational manufacturer and distributor of specialty 


                                     Page 3
<PAGE>

chemicals, a 15.1% beneficial shareholder of the Company, and the Company's 
partner in photopolymer resin development.  

     Unless otherwise indicated, all references to "CSC" include Ciba Specialty
Chemicals Inc. and its affiliates, including Ciba Specialty Chemicals Holding
and its wholly-owned subsidiaries in Canada, through which CSC holds its
interest in the Company, and the United States ("CSC US"), through which CSC
conducts its US operations.

CORPORATE STRUCTURE

     The Company is a Delaware corporation, and is the sole shareholder in 3D
Systems (Canada) Inc., a British Columbia corporation ("3D Canada"). 3D Canada
is the sole shareholder of 3D Systems, Inc., a California corporation ("3D
California"), which directly and through its subsidiaries conducts substantially
all of the Company's business.

     Unless otherwise indicated, all references in this document to the Company
include 3D Systems Corporation, 3-D Systems Inc., its British Columbia
predecessor, 3D Systems (Canada) Inc. and 3D Systems, Inc. and its subsidiaries.


PRODUCTS AND SERVICES

     For an analysis of revenues attributable to each of the Company's major
product and service groups, see "Item 7.  Management's Discussion and Analysis
of Results of Operations and Financial Condition - Results of Operations."

     SLA INDUSTRIAL SYSTEMS AND RELATED EQUIPMENT.  The Company currently is
manufacturing and marketing five SLA Industrial Systems-- the SLA 250 Smart
Start, the SLA-250 Series 50; the SLA-3500; the SLA-5000; and the SLA-7000.  All
models embody the stereolithography technology.  The models differ in their
features including the complexity and accuracy of part building, the maximum
size of objects that can be produced, and price.

     Each SLA system consists of an ultraviolet laser, an optical scanning
system that controls the laser beam, a resin vat, an elevator assembly and a
computer that controls the exposure and position of the laser beam and the
elevator, all of which are designed to work together.  SLA systems are capable
of making multiple objects at the same time; however, each SLA system is limited
in the size of the objects that it can make and, therefore, can make only scale
models of large objects or, alternatively, portions of large objects which are
then joined together.  For example, the maximum size of a model or other object
that can be created using the SLA-250 is 10 inches x 10 inches x 10 inches,
while the maximum size of a model or other object which can be created using the
SLA-7000 is 20 inches x 20 inches x 24 inches.

     The Company markets ultraviolet ovens ( "PCAs") used in conjunction with
SLA systems.  When the SLA system has finished making an object, some of the
plastic has not been fully cured.  Full curing requires an additional one to
five hours of exposure to ultraviolet illumination through the use of the
Company's PCAs.  The PCA provides uniform long wave ultraviolet illumination. 
The Company is currently offering three PCA models, the PCA 250, PCA 3500 and
PCA 5000.  Approximately 70% of all SLA systems sold by the Company have been
purchased with a PCA.

     SOLID OBJECT PRINTERS.   The Actua 2100 and its successor, the ThermoJet 
are network-ready systems and about the size of an office copier.  They use a 
hot melt ink jet technology to print models in successive layers with  a 
proprietary thermopolymer material and a print head with multiple jets 
oriented in a linear array.  The print head speeds back and forth as does a 
printer, printing layer upon layer of material which solidifies in seconds to 
form the physical model.  These printers offer a part building capacity of 10 
inches x 8 inches x 8 inches.

                                     Page 4
<PAGE>

     MATERIALS.  Under an agreement between the Company and CSC, the Company is
the exclusive worldwide distributor (other than Japan) to users of
stereolithographic systems of Ciba photopolymers (photosensitive resins) for
stereolithography (see "Marketing and Customers - Photopolymer Distribution
Agreement," below). Currently, the Company markets a total of thirteen different
resins,  which vary in building speed, accuracy, surface finish and strength. 
The Company anticipates that it may, from time to time, depending upon results
obtained under its Photopolymer Research Agreement described under "Research and
Development," below, market additional types of resins with varying properties. 
For its solid object printers, the Company develops its proprietary
thermopolymer materials and manufactures these directly or through toll
providers.

     SOFTWARE.  The Company develops and markets part preparation software for
personal computers and engineering workstations.  The software is designed to
enhance the interface between CAD/CAM systems and the Company's products.  
Solid CAD/CAM data is converted to the STL format in the CAD/CAM system and then
transmitted to a computer utilizing the Company's software, where the object can
be viewed, rotated, scaled and a model building structure added.  The software
then produces the SLA process instructions.  

     QUICKCAST.  The Company's QuickCast process  consists of special part
building software for making precision investment casting patterns using
stereolithography technology.  The investment casting process for manufacturing
metal parts is centuries old.  In typical investment casting, a foundry uses wax
patterns to generate molds, into which liquid metal is poured to form the part. 
The QuickCast process uses the Company's SLA systems to produce foundry-useable
mold patterns suitable for limited-run investment casting (each mold pattern can
only be used to produce one mold, which in turn can only be used to produce one
part).  While not intended for high-capacity manufacturing, the ability to
rapidly produce prototypes and short run production quantities of fully
functional complex metal parts, in a wide variety of metals, is a major
technological improvement in stereolithography.  Most of the SLA systems sold by
the Company have included the capability to use the QuickCast process. 

     MAINTENANCE.  All  systems sold  by the Company  include on-site hardware
and software maintenance service, during a warranty period (typically one year)
at no additional charge.  The Company defers a portion of its revenues for these
costs at the time of sale.  After the warranty period expires, the Company
offers these customers optional hardware and software maintenance contracts,
which are available on a monthly and annual basis.  Although purchasers  are not
required to enter into maintenance contracts with the Company, a majority of the
Company's U.S. and European customers  are parties to these contracts; many
others obtain maintenance services from the Company on a time and material
basis.  Customers acquiring systems from the Company's foreign distributors are
offered maintenance contracts by the distributors.  During 1996, 1997 and 1998,
revenues from maintenance contracts and maintenance services were approximately
$21.3 million,  $25.0 million, and $28.1 million, respectively.  As of December
31, 1998, the Company had a staff of 85 full-time employees who provide on-site
remedial and preventative maintenance services necessary to keep the equipment
in good operating condition.  To date, warranty expenses and product returns
have not been significant.

     3D SYSTEMS TECHNOLOGY CENTER.  The Company provides services from its
technology centers at its Valencia, California headquarters and at its office
located near  Frankfurt, Germany.  The 3D Systems Technology Centers utilize SLA
systems together with CAD/CAM and other data supplied by their customers to
produce models, prototypes, mold patterns and other parts for customers on a
contract basis.  The price for services offered by the Technology Centers varies
on the basis of the nature of the services requested.  The Technology Centers
currently focus their efforts on the development of new applications and
techniques in stereolithography and the development of new markets in which they
can demonstrate the advantages of stereolithography.  The Technology Centers
also enable the Company to keep abreast of developments in the applications of
stereolithography and serve as a means to introduce prospective buyers to
stereolithography.  

     3D KELTOOL.  The 3D Keltool process uses master patterns to produce highly
accurate steel tool core and cavity inserts for use in plastic injection molding
machines.  In 1998, the Company began licensing this technology to its customers
for their direct use.  Since acquiring the 3D Keltool assets and operations in
September 1996 and through 1998, the Company produced 3D Keltool inserts for its
customers, using the 3D Keltool process, out of its St. Paul, Minnesota
facility.  In the first quarter of 1999, the Company sold the St. Paul
operations to Rapid 


                                     Page 5
<PAGE>

Tooling Technologies, a subsidiary of Rapid Design Technologies ("RDT").  As 
part of this agreement, RDT was issued a multi year license for the use of 
the 3D Keltool process.  

     RECENT PRODUCT INTRODUCTIONS.  In order to improve and expand the
capabilities of its  systems and related software and materials, as well as to
enhance its portfolio of proprietary intellectual properties, the Company
historically has devoted a significant portion of its resources to research and
development activities.  Recent  product introductions include the following: 

     SL5510 resin for the SLA-350 and SLA-3500 was made commercially available
January 1998.  This resin has improved performance characteristics that include
exceptional humidity resistance, low viscosity and high accuracy, making it well
suited for master patterns and the use of 3D's QuickCast build style for
investment casting of metal parts.

     SL5530HT resin was announced in December 1998.  Designed specifically for
use with the SLA 350, 3500, 5000 and 7000, SL5530HT resin is a breakthrough in
materials development.  SL5530HT can resist very high temperatures in excess of
200 C/392 F - twice the resistance of any other resin today.  It also provides
optical clarity for flow visualization and accuracy that mirrors the dimensions
of the end-use part.   

     3D LIGHTYEAR part preparation software was released in the first quarter of
1999.  3D Lightyear exploits the power of the Windows NT operating system,
delivering functionality that extends beyond the capabilities of Unix-based
Maestro. 

     SLA 7000 is 400% faster, on average, than the next fastest SLA Industrial
System from 3D Systems.  The SLA-7000 has a dual spot laser that reduces
downtime and errors while producing parts at .001 inch layers thickness in far
less post processing time.  Commercial availability was announced in the first
quarter of 1999.

     THERMOJET SOLID OBJECT PRINTER is the successor to the Actua 2100, offering
a significant improvement in speed, up to 300% faster.   In addition, the
ThermoJet uses a new material, with improved part capabilities and color
capability.  Commercial availability was announced in the first quarter of 1999.


RESEARCH AND DEVELOPMENT

     The ability of the Company to compete successfully depends, among other 
things, on its ability to design and develop new products and to refine 
existing products.  For the foreseeable future, the Company anticipates that 
its research and development efforts will be focused on developing new 
methods of solid imaging technology, improving and refining its existing 
Solid Object Printer and SLA systems and developing software to facilitate 
the interface between its solid imaging systems and CAD/CAM programs.  
Research and development expenses decreased in 1998 to $9.4  million, down 
from $11.0 million in 1997.   The decrease in research and development 
expenses in 1998 was primarily a result of the write-off during the third 
quarter of 1997 of acquired in-process technology valued at approximately 
$2.1 million in connection with the EOS acquisition (see Note 7 of Notes to 
Consolidated Financial Statements) offset in part by increased personnel and 
experimental material costs related to certain development projects.  Based 
on the Company's historical expenditures related to research and development 
and its current development goals, the Company anticipates for the 
foreseeable future, research and development expenses will be equal to 
approximately ten percent of sales.  This is a forward-looking statement, 
however, and, as with any such statement, is subject to risk.  For example, 
if total sales of the Company for any particular period do not meet the 
anticipated sales of the Company for that year, research and development 
expenses as a percentage of sales may exceed ten percent. As of December 31, 
1998, 66 employees or contractors of the Company were devoting substantially 
all of their time to research and development activities, compared to 60 
employees at December 31, 1997.


                                     Page 6
<PAGE>

     The Company believes that further refinements in stereolithography will 
depend upon improvements not only in the SLA systems, but also in the 
chemical makeup of the resins used in the fabrication process.  To this end, 
the Company has dedicated a significant amount of time to the development of 
new resins. To pursue this goal, the Company and CSC are parties to a 
Research and Development Agreement (as revised, the "Photopolymer Research 
Agreement") providing for the development of photopolymers, 
photopolymerizable monomers, photoinitiators and other resins for use with 
the SLA systems.  Subject to certain conditions, the Photopolymer Research 
Agreement will remain in effect until either party gives the other six months 
advance notice of its determination to terminate the agreement.  There can be 
no assurance that this agreement will remain in place. The termination of 
this agreement could have a material adverse effect on the Company's revenues 
results of operations, liquidity, and financial position. Pursuant to the 
Photopolymer Research Agreement, the two companies work jointly, with each 
company funding its own portion of the research.  Ownership of any inventions 
or know-how, whether patented or not, will accrue to CSC if they are chemical 
in nature and to the Company if they relate to the stereolithographic process.

             The foregoing discussion relating to the Company's research and
development activities includes statements that involve risks and uncertainties.
For a discussion of the factors associated with such forward looking statements
which could cause actual results to differ materially from those projected in
the statements, see "Cautionary Statements and Risk Factors- We Must Keep Pace
with Technological Change and Introduce New Products to Remain Competitive," and
"Our New Products May Not Be Commercially Accepted."

MARKETING AND CUSTOMERS

     The Company's sales and marketing strategy focuses on an internal sales 
organization, which is responsible for overseeing worldwide sales and 
value-added resellers, as well as the utilization of knowledgeable 
international distributors. The Company employs a direct sales force 
consisting of sales persons and application specialists that provide 
technical sales support.  At December 31, 1998, the Company's worldwide sales 
and support staff consisted of 64 employees that were primarily located in 
the U.S. and Europe. The Company has offices in the U.S. in California, 
Michigan, Pennsylvania, and Texas, its European offices are located near 
Frankfurt, London, Paris, Barcelona and Milan, and the Hong Kong office 
services Asia Pacific.  

     In recent years, the Company's domestic sales strategy has focused on an
internal sales organization as well as the utilization of sales agents
(primarily, independent sales representatives in the machine tools industry).
These sales agents, however, were not producing the level of sales expected by
the Company.  Additionally, the Company believed it could obtain better
visibility and contact with its customers by utilizing a direct sales force. 
Accordingly, in August 1996, the Company terminated its arrangements with all of
its sales agents and began recruiting additional personnel to strengthen its
internal sales and support organization.   During the second half of 1997 the
Company completed the initial staffing of its sales and support organization.

     INTERNATIONAL DISTRIBUTORS.    As of December 31, 1998, the Company had
entered into agreements with eight distributors in the Pacific Rim, five in
Europe and two in Latin America.  International distributors are responsible for
marketing, sales, system installation, service and support to their customers.

     International sales accounted for 33.8%, 41.5% and 44.1% of total sales in
the years ended December 31, 1996, 1997, and 1998, respectively.  See Note 17 of
Notes to Consolidated Financial Statements.  For a discussion of risks
associated with international operations, see "Cautionary Statements and Risk
Factors -- There are Many Risks Associated with International Business."

     CUSTOMERS.  The Company's  customers include major companies in a broad
range of industries including manufacturers of automotive, aerospace, computer,
electronic, consumer and medical products.  Purchasers of the Company's  systems
include, among others, Allied Signal Inc., AMP, Inc., Apple Computer, Inc.,
Boeing Company, Canstar Sports, Inc., Chrysler Corp., Daimler-Benz AG, Eastman
Kodak Company, General Electric Company, General Motors Corporation, GM Hughes
Electronics Corporation, International Business Machines Corporation, Johnson &
Johnson, Motorola, Inc., Pratt & Whitney and Texas Instruments Inc.  The Company
also sells its products to independent service bureaus which, for a fee, provide
stereolithographic services to their customers.  


                                     Page 7
<PAGE>

     LEASING AND RENTAL PROGRAMS.  As part of its marketing activities, 3D
Capital Corporation ("3D Capital"), a wholly-owned subsidiary of the Company,
was formed in August of 1996 to provide lease financing for qualified U.S.
customers purchasing SLA systems. The leases are accounted for as sales-type
leases where the present value of the minimum payments, net of costs, are
recorded as sales.   During 1997 and 1998, the Company sold and assigned a
portion of their lease receivables and  expects to continue to periodically sell
or assign a portion of the lease receivables as a future source of financing.

     In addition to sales-type leases, the Company occasionally offers selected
credit-worthy companies the right to rent its solid imaging system for
evaluation purposes. Substantially all of the customers who have participated in
the rental program have subsequently purchased a solid imaging system.

     PHOTOPOLYMER DISTRIBUTION AGREEMENT.  Pursuant to an agreement with CSC US,
and subject to conditions set forth in the agreement, the Company is the
exclusive worldwide distributor to users of stereolithographic processes of all
Ciba Specialty Chemicals stereolithography photopolymers.  At the Company's
request, an affiliate of CSC US currently sells such photopolymers in Japan to
the Company's Japanese distributor.  Subject to certain conditions, so long as
CSC US provides adequate supplies, the Company is required to fill all of its
requirements for its photopolymers through purchases from CSC US.   Subject to
certain conditions, the agreement will remain in effect until  either party
gives the other six months advance notice of termination.  There can be no
assurance that this agreement will remain in place.  Though the Company believes
it can obtain alternate agreements from other manufacturers, the termination of
this agreement or interruption of supply  could have a material adverse effect
on the Company's revenues, results of operations, liquidity and financial
position.  See "Cautionary Statements and Risk Factors --We Depend on a Single
or Limited Suppliers for Certain of our Components."

     CUSTOMER SUPPORT AND SERVICE.  Before installation of an SLA system, a new
purchaser typically receives training at the Company's facilities.  During the
first several days after installation, an applications engineer remains at the
customer location to ensure that the customer is able to operate the SLA system
effectively and to answer any questions that may arise.  The Company also makes
available to its customers, for a fee, additional training courses in SLA system
features and applications.

     The Company and its distributors offer maintenance contracts to their
customers.  See "Products and Services," above.  The Company also makes
available in the U.S. a hotline to all of its users with maintenance contracts.
The hotline is staffed with technical representatives who answer questions and
arrange for on-site remedial services if necessary.  The hotline is available
Monday through Friday, 8:00 a.m. Eastern time to 5:00 p.m. Pacific time.

     The Company co-founded and currently participates in both domestic and
international User Groups which currently include a substantial number of the
Company's customers.  The User Groups organize an annual conference in both the
United States and Europe, at which the Company makes presentations relating to
updates in stereolithography, changes the Company has implemented in its systems
and related equipment, resins and software and future ideas and programs the
Company intends to pursue in the upcoming years.

     BACKLOG. At December 31, 1998, the Company had orders (with scheduled
delivery dates) for 73 systems aggregating approximately $8.8 million, as
compared to systems aggregating approximately $3.5 million at December 31, 1997
and systems aggregating approximately $9.0 million at December 31, 1996.  It is
anticipated that all orders included in the current backlog will be shipped by
June 30, 1999. As a matter of policy, the Company affords its customers the
right to cancel any system order at any time prior to their scheduled delivery
dates. Historically, the number of system orders canceled has not been
significant. Nonetheless, no assurance can be given that all orders in backlog
will be shipped. Backlog may not be indicative of future expected sales.

PRODUCTION AND SUPPLIES

     The Company assembles all of its systems at its 67,000 square foot facility
in Grand Junction, Colorado. 

     The Company purchases the major component parts for its systems from
outside sources and arranges with contract manufacturers for the manufacture of
subassemblies.  The Company integrates the subassemblies and effects final
assembly of all systems at its production facility.  The Company performs
numerous diagnostic tests and quality control procedures on each system  to
assure its operability and reliability.

     Although there is more than one potential supplier for many material
components parts and subassemblies, several of the critical components,
materials, and subassemblies, including lasers, resins, and certain ink jet
components, are currently provided by a single or limited sources.  Resin
distributed by the Company are supplied exclusively by CSC under an agreement
subject to certain conditions, and either party has the right to terminate this
agreement subject to six months notice.  The reliance on sole or limited source
vendors by the Company involves risks, including the possibility of shortages of
certain key components, product performance shortfalls, and reduced control over
delivery schedules, manufacturing capability, quality and costs.  Business
disruptions, financial difficulties, or any significant change in condition of
relationship of a sole or limited source supplier of any particular component
could have a material and adverse effect on  the Company's revenues, results of
operations, liquidity and financial condition by increasing the cost of goods
sold or reducing the availability of such components.   An unanticipated change
in the source of supply of these components or unanticipated supply limitations
could adversely affect the Company's ability to meet its product orders. 

COMPETITION AND PATENT RIGHTS

     The Company believes no products technologically similar to the Company's
SLA systems are being sold in significant quantities in the United States;
however, products similar to the Company's SLA systems have been manufactured
and sold by other companies in the Pacific Rim and in Europe.  In addition, the
Company believes that there are other companies researching, designing,
developing and marketing other types of solid imaging equipment in the United
States and in foreign markets, and additional companies may announce plans to
enter the solid imaging business, either with equipment similar to that marketed
by the Company, or with other types of equipment.  See "Cautionary Statements
and Risk Factors -- Intense Competition."

     Although it is estimated that there are approximately 19 companies
currently manufacturing rapid prototyping equipment, the following is a brief
description of competing products or technologies of the companies that the
Company believes are its current primary competitors.  DTM, Inc., in conjunction
with B.F. Goodrich, markets systems based on a technology called  Selective
Laser Sintering, which uses a powdered material which is sintered (solidified by
heating) by a laser.  Helisys, Inc. markets systems based on a technology called
Laminated Object Manufacturing, which builds parts from sheets of paper or other
material that are laminated together with cross-sectional patterns being laser
cut into each sheet of paper.  Stratasys, Inc. ("Stratasys") markets a fused
deposition modeling process that builds objects by dispensing individual layers
of thermoplastic material through a temperature controlled head.

     With respect to the solid object printer concept, the Company believes that
the following companies are its current primary competitors:  Stratasys, Sanders
Prototyping, and  Z Corporation.

     Products similar to the Company's stereolithography products are being
marketed  in Japan by NTT Data and D-MEC.  During 1998, the Company signed
patent cross license agreements with NTT Data and NTT Data CMET (marketed by NTT
Data) and with Sony Corporation (marketed by D-MEC).  Under these agreements, 3D
Systems has granted a non exclusive license to produce and sell
stereolithography systems in the Asia Pacific area, and received a non-exclusive
worldwide license.  In addition, E.I. du Pont de Nemours and Company ("Du Pont")
has licensed certain stereolithography technology to Teijin Seiki of Japan and
Aaroflex of Virginia, USA.  The Company believes that other Japanese companies
are also developing and marketing products similar to those of the Company. 
However, the Company does not have reliable data with respect to these efforts. 
During 1996, Aaroflex, Inc. ("Aaroflex"), headquartered in Virginia, publicly
announced the availability and claimed that it has 


                                     Page 9
<PAGE>

sold in the U.S., although not delivered, equipment which offers the same 
functions as the Company's SLA systems.  (See "Item 3 Legal Proceedings").

     The Company believes that currently available alternatives to 
stereolithography generally are not able to produce models having the 
dimensional accuracy or fine surface finish of models provided by the 
Company's stereolithography process.  However, competitors have successfully 
marketed their products to the Company's existing and potential customers.  
Furthermore, in many cases, the existence of these competitors extends the 
purchasing time while customers investigate alternative systems.  The Company 
competes primarily on the basis of the quality of its products and the 
advanced state of its technology.  Although the Company does not rely totally 
on its patents to compete, the Company believes that the patents will help 
the Company maintain its leading position in the solid imaging field in the 
United States and Europe. See "Proprietary Protection," below and "Cautionary 
Statements and Risk Factors -- Patents and Proprietary Information is 
Critical to Our Success."

     A number of companies, including Du Pont, are currently selling
stereolithography resins, which either complement or compete with those
distributed by the Company.   Within the limits of its obligations under the
Photopolymer Research Agreement (see "Research and Development," above), the
Company encourages chemical companies to develop  stereolithography resins that
are compatible with its SLA equipment, but it also works closely with CSC US to
remain competitive in the resin market.  The Company believes that it currently
supplies resins to owners of a majority of the  SLA systems currently installed
worldwide.

     The Company does not believe that it currently has any significant
competition for its maintenance services, although some of the Company's
customers perform their own maintenance in-house.  The Company offers software
and hardware maintenance contracts to its customers (see "Products and Services"
above).  Maintenance for SLA systems sold internationally is offered by the
Company's distributors (see "Marketing and Customers" above).

     Future competition is expected to arise both from the development of new
technologies or  techniques not encompassed by the patents held by or licensed
to the Company and through improvements to existing technologies, such as
automated machining.  The Company has determined to follow a strategy of
continuing product development and aggressive patent prosecution to protect
itself to the extent possible in these areas.  

PROPRIETARY PROTECTION

     The stereolithography technology used by the Company in its products was
developed by Charles W. Hull, the Company's Vice Chairman, while employed by
UVP, Inc.  This technology was originally patented by UVP, Inc., subsequently
licensed to the Company in 1986 and acquired by the Company in 1990.

     At December 31, 1998, the Company had received approximately 160 patents
which includes 75 in the U.S., 49 in Europe, 6 in Japan and 30 other foreign
patents.   At that date, the Company had 30 pending patent applications in the
United States, 54 in the Pacific Rim, 15 in Europe, 10 in Canada and 6 in Latin
America.  As new developments and components to the technology are discovered,
the Company intends to apply for additional patents. 

     During January 1997, 3D Systems filed a patent infringement lawsuit against
Aaroflex, Inc. The lawsuit seeks compensation from Aaroflex for utilizing
certain stereolithography technology which the Company alleges is covered by six
of its U.S. patents and seeks other damages and attorneys fees as well as an
injunction barring Aaroflex from marketing its products using technology covered
by the Company's patents (see "Item 3. Legal Proceedings").  

     Application for a patent offers no assurance that a patent will be issued
as applied for.  Issuance of a patent offers no assurance that the patent can be
protected against any claims of invalidation or that the patent can be enforced
against any infringement. In addition, litigation of patent issues can be costly
and time-consuming.  See "Cautionary Statements and Risk Factors -- Patents and
Proprietary Protection."


                                     Page 10
<PAGE>

EMPLOYEES

     At December 31, 1998, the Company had 465 full-time employees, and 26
independent contractors.  None of these employees or independent contractors are
covered by labor agreements.  The Company considers its relations with its
employees and its independent contractors to be satisfactory.


CAUTIONARY STATEMENTS AND RISK FACTORS

     Several of the matters discussed in this document contain certain 
forward looking statements that involve risks and uncertainties.  Factors 
associated with the forward looking statements which could cause actual 
results to differ materially from those projected in the statements appear 
below.  In addition to the other information contained in this document, 
readers should carefully consider the following cautionary statements and 
risk factors. 

FLUCTUATIONS IN QUARTERLY RESULTS - OUR OPERATING RESULTS VARY FROM QUARTER TO
QUARTER WHICH COULD IMPACT OUR STOCK PRICE

     Our operating results fluctuate from quarter to quarter and may continue to
fluctuate in the future.  We believe that quarter to quarter or annual
comparisons of our operating results are not a good indication of our future
performance.  In some quarters it is possible that our results could be below
analysts' expectations and investors.  If so, the price of our common stock may
fall.

     Many factors may cause these fluctuations.  Some of these factors are
beyond our control.  The factors include:

     -    the acceptance and reliability of new products in the market
     -    the size and timing of product shipments
     -    general world economic conditions
     -    changes in the mix of products and services sold
     -    currency and economic fluctuations in foreign markets and other
          factors affecting international sales
     -    delays in the introduction of new services/products
     -    price competition
     -    the impact of changing technologies

     In addition, certain components we use require an order lead time of three
months or longer.  Other components that are currently readily available may
become more difficult to obtain in the future.  We may experience delays in the
receipt of certain key components.  To meet forecasted production levels, we may
be required to commit to certain long lead time items prior to receiving orders
for our products.  If our forecasts exceed actual orders, we may hold large
inventories of slow moving or unusable parts, which could have an adverse affect
on our cash flow and results of operations.

     Because of all of these factors, we cannot assure you that we will achieve
or sustain quarterly or annual profitability in the future.

THE MIX OF PRODUCTS SOLD AFFECTS OUR OVERALL PROFIT MARGINS

     We continuously are expanding our product offerings as well as increasing
the number of geographic markets in which we operate and distribution channels
that we use in order to reach the various markets and customers.  This variety
of products, markets and channels results in a range of gross margins and
operating income which can cause substantial quarterly fluctuations depending on
the mix of product shipments quarter to quarter.  We may experience significant
quarterly fluctuations in gross margins or net income due to the impact of the
mix of 


                                     Page 11
<PAGE>

products, channels, or geographic markets utilized from period to period. 
Also, the changing mix of products, channels, and markets used over time may 
result in lower average gross margins and returns.

WE MUST KEEP PACE WITH TECHNOLOGICAL CHANGE AND INTRODUCE NEW PRODUCTS TO REMAIN
COMPETITIVE

     To remain competitive, we must continue to enhance and improve the
functionality and features of our products, services and technologies.  The
solid imaging industry is characterized by rapid technological change, changes
in user and customer requirements and preferences, frequent new product and
service introductions embodying new technologies and the emergence of new
industry standards and practices.  These developments could render our existing
products and proprietary technology and systems obsolete.  Our success will
depend, in part, on our ability to:

     -    obtain leading technologies useful in our business
     -    enhance our existing products
     -    develop new products and technologies that address the increasingly
          sophisticated and varied needs of existing and prospective customers
     -    respond to technological advances and emerging industry standards and
          practices on a cost-effective and timely basis

     Also, our competitors may develop new technologies that render our existing
products and services obsolete.  We believe that our future success will depend
on our ability to deliver products which meet changing technology and customer
needs.

OUR NEW PRODUCTS MAY NOT BE COMMERCIALLY ACCEPTED

     During the last 18 months, we have developed and introduced a 
significant number of new products to the market, including equipment, 
software and materials.  These products undergo thorough quality assurance 
testing.  However, problems may arise in connection with the use of a new 
product and we cannot assure you that we will be able to fix any problems 
that arise timely, or at all.  Also, we cannot assure you that any new 
products we develop will be commercially accepted.  If there are many 
problems with our new products, or if these products are not accepted by the 
marketplace, our results of operations and financial condition could be 
materially adversely effected.

WE DEPEND ON A SINGLE OR LIMITED SUPPLIERS FOR CERTAIN OF OUR COMPONENTS

     There are several potential suppliers of the material components, parts and
subassemblies for our products.  However, we currently use only one or a limited
number of suppliers for several of the critical components, parts and
subassemblies, including our lasers, resins and certain ink jet components.  CSC
supplies us with the resins we distribute pursuant to an agreement which either
party has the right to terminate with six months advance notice.   Our reliance
on a limited number of vendors involves many risks including:

     -    shortages of certain key components
     -    product performance shortfalls
     -    reduced control over delivery schedules, manufacturing capabilities,
          quality and costs

If any of our suppliers suffers business disruptions, financial difficulties, 
or if there is any significant change in condition of our relationship with 
the supplier, our costs of goods sold may increase or we may be unable to 
obtain these key components for our products.  In either event, our revenues, 
results of operations and liquidity and financial condition would be 
adversely affected. While we believe that we can obtain most of the 
components necessary for our products from other manufacturers, any 
unanticipated change in the source of supply, or unanticipated supply 
limitations, could adversely affect our ability to meet our product orders.

THERE ARE MANY RISKS ASSOCIATED WITH INTERNATIONAL BUSINESS

A material portion of our sales are to customers in foreign countries.  Revenues
from international customers accounted for approximately 44.1% of total revenues
in 1998, 41.5% of total revenues in 1997 and 33.8% of total 


                                     Page 12
<PAGE>

revenues in 1996. There are many risks inherent in our international business 
activities.  Our foreign operations could be adversely affected by:

     -    unexpected changes in regulatory requirements
     -    export controls, tariffs and other barriers
     -    social and political risks
     -    fluctuations in currency exchange rates
     -    seasonal reductions in business activity during the summer months in
          Europe and in certain  other parts of the world
     -    reduced protection for intellectual property rights in some countries
     -    difficulties in staffing and managing foreign operations
     -    taxation
     -    other factors, depending on the country in which an opportunity arises

     In addition to the general risks associated with our international sales
and operations, we will be subject to risks specific to the individual countries
in which we do business.

     The financial problems in Asia have been significant and have impacted
international financial markets.  The Asian markets may continue to deteriorate
which could have a substantial adverse impact on our ability to collect our
receivables from Asian customers.   At December 31, 1998, customer receivables
from Asia generally were in accordance with agreed payment terms.


THE ADOPTION OF THE EURO PRESENTS UNCERTAINTIES

     In January 1999, the New "Euro" currency was introduced in certain European
countries that are part of the European Monetary Union ("EMU").  Beginning in
2003, all EMU countries are expected to be operating with the Euro as their
single currency.  A significant amount of uncertainty exists as to the effect
the Euro will have on the marketplace generally.  Some of the rules and
regulations relating to the governance of the currency have not yet been defined
and finalized. 

     We believe that our internal systems and financial institution vendors can
handle the Euro conversion and we are examining current marketing and pricing
policies and strategies that we may put in place upon conversion to the Euro. 
The cost of our effort is not expected to materially affect our results of
operations or financial condition.  However, we cannot assure you that we have
identified all issues related to the Euro conversion and that any additional
issues would not materially hurt our results of operations or financial
condition.  For example, the conversion to the Euro may have competitive
implications on our pricing and marketing strategies and we may be at risk to
the extent our principal European customers are unable to deal effectively with
the impact of the Euro conversion. 

WE FACE YEAR 2000 RISKS

     Computer-based systems that require date/time calculations to operate
correctly are subject to miscalculations and system failures on and after the
year 2000.  This is known as the Y2K problem.  The Y2K problem affects systems
that were developed to accept two digit entries for the year in the date code
field.  After midnight on December 31,1999, these systems may recognize a date
using '00' as the year 1900 rather than the year 2000.  Another known issue is
that many systems will not recognize the year 2000 as a leap year.  The Y2K
problem is pervasive in that it goes beyond internal systems to involve supply
and distribution chains and extends to both public and private infrastructure
services including water, gas, electricity, transportation and communications.

     We believe that our current products are year 2000 compliant.  We also have
evaluated all products sold since inception for year 2000 readiness, and are
providing the results of our analysis and potential impact and resolutions to
our customers.  We expect to complete all of the necessary software 


                                     Page 13
<PAGE>

and hardware upgrade pathways in the first quarter of 1999.  We plan to offer 
the actual software patches that may be required to our customers by the end 
of the third quarter of 1999.  We believe that all of our products will meet 
basic functionality requirements.  However, since we cannot anticipate all 
specific customer situations and uses, we may see an increase in warranty and 
other claims as a result of the year 2000 transition.  For these reasons, the 
increase in customer claims could have a material adverse impact on our 
results of operations and financial condition.

     We are in the process of completing a comprehensive evaluation of our
internal systems and equipment.  We are currently updating certain critical
infrastructure and management systems to meet year 2000 requirements.  These
upgrades also will meet the Euro dollar requirements and expand our
capabilities.  We are conducting transaction testing to evaluate compliance of
the overall system infrastructure.  To date, we have substantially completed the
risk analysis on all U.S.-based systems and have substantially completed all of
the infrastructure upgrades on these systems as well as certain European
operations.  We plan to complete the risk analysis of foreign operations in the
first quarter of 1999, as well as to implement the year 2000 compliance upgrade
of our core ERP system.  We believe that the vast majority of Y2K-related issues
with respect to internal business systems will be inventoried, analyzed and
resolved by the end of the second quarter of 1999, and that certification and/or
testing will be completed by the end of the third quarter of 1999.   If we do
not identify all of our infrastructure and systems that may be affected by the
year 2000 transition or do not timely update our infrastructure and management
systems to meet year 2000 requirements, our results of operations and financial
condition will be adversely affected.
     
     We are currently assessing the year 2000 readiness of our third-party
supplied software, computer technology and other services and of our vendors and
suppliers.  We have completed a survey of key suppliers and evaluated their
individual risk potential as well as the risk potential of their suppliers. 
Also, we have conducted site surveys of certain critical or sole source
suppliers.  Based on these surveys, we believe that a substantial majority of
our suppliers are Y2K compliant or expect to be Y2K compliant by the fourth
quarter of 1999.  We began evaluating next tier suppliers in the first quarter
of 1999.  Our contingency strategies include seeking alternative sources of
supplies or acquiring sufficient material to support our operations for the
first half of 2000.  We believe we have sufficient alternatives and liquidity to
meet our contingency strategy.  However, the failure of our third party
suppliers to be year 2000 compliant could have a material adverse effect on us.
     
     Year 2000 compliance is an issue for virtually all businesses whose
computer systems and applications may require significant hardware or software
upgrades or modifications.  These companies may plan to devote a substantial
portion of their capital spending to fund upgrades and modifications, which
could divert spending away from capital manufacturing equipment spending.  These
changes in customers' spending patterns may cause an adverse result on our
sales, operating results and financial condition.

PATENTS AND PROPRIETARY INFORMATION IS CRITICAL TO OUR SUCCESS

     We regard our copyrights, service marks, trademarks, trade secrets, patents
and similar intellectual property as critical to our success.  At December 31,
1998, we had received approximately 160 patents which includes 75 in the U.S.,
49 in Europe, 6 in Japan, and 30 other foreign patents.  At that date, we had 30
pending patent applications with the United States, 54 in the Pacific Rim, 15 in
Europe, 10 in Canada and 6 in Latin America.   As we discover new developments
and components to the technology, we intend to apply for additional patents. 
Effective trademark, service mark, copyright, patent and trade secret protection
may not be available in every country in which our products and service are made
available.  We cannot be certain that the pending patent applications will be
granted or that we have taken adequate steps to protect our proprietary rights,
especially in countries where the laws may not protect our rights as fully as in
the United States.  Moreover, our competitors may 


                                     Page 14
<PAGE>

independently develop or initiate technologies that are substantially similar 
or superior to ours.  We cannot be certain that we will be able to maintain a 
meaningful technological advantage over our competitors.  

     Third parties may infringe or misappropriate our proprietary rights and we
intend to pursue enforcement and defense of our patents and other proprietary
rights.  We could incur significant expenses in preserving our proprietary
rights and these costs could have a material adverse effect on our results of
operations, liquidity and financial condition and could cause significant
fluctuations in results from quarter to quarter.  We are currently pursuing a
patent infringement action in the central District of California against
Aaroflex, Inc., and in Japan against Teijin Seiki Co. Ltd. (See "Item 3. Legal
Proceedings.")
     
INTENSE COMPETITION 

     The solid imaging industry is highly competitive and subject to
technological change, innovation, and new product introductions.  Certain of our
existing and potential competitors are researching, designing, developing and
marketing other types of equipment.  Some of these competitors have financial,
marketing, manufacturing, distribution and other resources substantially greater
than ours.  In many cases, the existence of these competitors extends the
purchase decision time as customers investigate the alternative products and
solutions.  Also, these competitors have marketed these products successfully to
our existing and potential customers.  In addition, a number of companies
currently sell stereolithography resins, which both complement and compete with
the resins we distribute. 
     
     We expect future competition may arise from the development of allied or
related techniques which are not encompassed by our patents, the issuance of
patents to other companies which inhibit our ability to develop certain
products, and improvement to existing technologies.  Increased competition could
result in price reductions for our products, reduced margins, and loss of market
share, any of which could adversely impact our business.  We have determined to
follow a strategy of continuing product development and aggressive patent
prosecution to protect our competitive position to the extent practicable.  We
cannot assure you that we will be able to maintain our leading position in the
field of rapid prototyping or continue to compete successfully against current
and future sources of competition.  These competitive pressures may adversely
affect our profitability and financial performance.  See "Business -
Competition."

VOLATILITY OF STOCK PRICE

     Historically, our stock price has been volatile.  The prices of the common
stock have ranged from $5.50 to $11.86 during the 52-week period ended February
28, 1999.  See "Item 5. Market for Registrant's Common Stock and Related
Stockholder Matters."  

     Factors that may have significant impact on our market price of our stock
include:

     -    future announcements  concerning our developments or those of our
          competitors, including the receipt of substantial orders for products
     -    quality deficiencies in services or products
     -    results of technological innovations
     -    new commercial products
     -    changes in recommendations of securities analysts
     -    proprietary rights or product or patent litigation

     Our future earnings and stock price may be subject to significant
volatility, particularly on a quarterly basis.  Shortfalls in our revenues or
earnings in any given period relative to the levels expected by securities
analysts could immediately, significantly and adversely affect the trading price
of our common stock.

WE ARE SUBJECT TO ANTI-TAKEOVER PROVISIONS

     The Board of Directors is authorized to issue up to 5,000,000 shares of
preferred stock.  The Board also is authorized to determine the price, rights,
preferences and privileges of those shares without any further vote or 


                                     Page 15
<PAGE>

action by the stockholders.  The rights of the holders of any preferred stock 
may adversely affect the rights of holders of common stock.  Our ability to 
issue preferred stock gives us flexibility concerning possible acquisitions 
and financings, but it could make it more difficult for a third party to 
acquire a majority of our outstanding voting stock.  In addition, any 
preferred stock to be issued may have other rights, including economic 
rights, senior to the common stock which could have a material adverse effect 
on the market value of the common stock.

     We are subject to Delaware laws that could have the effect of delaying,
deterring or preventing a change in control of the Company.  One of these laws
prohibits us from engaging in a business combination with any interested
stockholder for a period of three years from the date the person became an
interested stockholder, unless some conditions are met.  In addition, provisions
of our Certificate of Incorporation and By-laws, could have the effect of
discouraging potential takeover attempts or making it more difficult for
stockholders to change management.  

     In addition, we have adopted a Stockholders Rights Plan (see Note 12(b) of
Notes to Consolidated Financial Statements).  Under the Rights Plan, we
distributed a dividend of one right for each outstanding share of our common
stock.  These rights will cause substantial dilution if a person or group
attempts to acquire us on terms not approved by our Board of Directors and may
have the effect of deterring hostile takeover attempts.


ITEM 2.   PROPERTIES

     The Company's principal administrative, sales and marketing, product
development, Technology Center and training facilities are located in a 78,320
square foot building in Valencia, California under a lease which expires on
December 31, 2002.   The Company also leases sales and service offices in four
other states (California, Michigan, Pennsylvania and Texas) and in four
countries in the European Community (France, Germany, the United Kingdom and
Italy).

     The Company's manufacturing and customer support operations are located in
a 67,000 square foot facility located in Grand Junction, Colorado (the "Colorado
Facility").  The Company constructed the Colorado Facility pursuant to an
agreement with the Mesa County Economic Development Council, Inc. executed in
October 1995.  Following the completion of the Colorado Facility in June 1996,
the Company relocated its manufacturing and customer support operations from its
Valencia facility to the Colorado Facility during the third quarter of 1996. 
During the fourth quarter of 1996, all of the Company's manufacturing activities
were performed at the Colorado Facility.  During August 1996, the Company
completed a $4.9 million variable rate industrial development bond financing of
the Colorado Facility.

     In connection with the asset acquisition of Keltool, Inc. in September
1996, the Company assumed Keltool's obligations under an existing lease for
approximately 6,000 square feet located in St. Paul, Minnesota.  In the first
quarter of 1999, the Company completed the sale of its St. Paul operations and
assigned this lease to the acquirer.  In addition, the Company executed a lease
for approximately 21,000 square feet in Valencia, California which expires on
June 30, 2000 for its 3D Keltool operations.  The Company's occupancy of this
facility commenced  in February 1997.

     For information concerning obligations of the Company under its leases, see
Note 18(a) of Notes to Consolidated Financial Statements.  For information
concerning the Company's Colorado Facility, see Note 11. 

     The Company believes that the facilities described above will be adequate
to meet its needs for the foreseeable future.
     

ITEM 3.   LEGAL PROCEEDINGS

     3D SYSTEMS, INC. V. AAROFLEX ET AL.  On January 13, 1997, The Company filed
a complaint ("Complaint") in the United States District Court, Central District
of California, against Aarotech Laboratories, Inc. ("Aarotech"), Aaroflex, Inc.
("Aaroflex") and Albert C. Young ("Young").  Aaroflex is the parent corporation
of Aarotech.  Young is 


                                     Page 16
<PAGE>

the Chairman of the Board and Chief Executive Officer of both Aarotech and 
Aaroflex.  The Complaint alleges that stereolithography equipment 
manufactured by Aaroflex infringes on six of the Company's patents. The 
Company seeks damages and injunctive relief from the defendants.  The 
defendants have threatened to sue the Company for trade libel.  To date, the 
defendants have not filed such a suit.

     The defendants filed a motion to dismiss the complaint or transfer the case
to their home district in Virginia.  The Court granted this motion to dismiss on
the agenda of lack of personal jurisdiction.  The Federal Circuit Court of
Appeals has reversed this district court's decision insofar as it relates to
Aaroflex, Inc. and the action against Aaroflex, Inc. is proceeding in the
District Court.     

     3D SYSTEMS, INC. V. TEIJIN SEIKI CO. LTD  On March 21, 1997, the Company
filed a patent infringement action in District Court in Osaka, Japan under one
of its Japanese patents, alleging infringement, and seeking damages and
injunctive relief from the defendant.  The action is in the early stages of
prosecution.

     CENTURI CORP., DBA ESTES INDUS., COX ACQUISITION CORP., DBA COX V. 3D
SYSTEMS CORP., ROGERS TOOL & DIE, In January 1997, 3D Systems, Inc. entered into
two contracts with Centuri Corp., dba Estes Indus., Cox Acquisition Corp., dba
Cox ("Cox") under which 3D was to create certain tooling for Cox.  Cox purported
to terminate the contracts in or about August 1997.

     On September 16, 1997, Cox initiated a lawsuit against 3D in Los Angeles
Superior Court for Breach of Oral Contract, Fraud, Negligent Misrepresentation,
Conversion, Money Had and Received, and Accounting.  The suit also named Rogers
Tool & Die, a contractor hired by Cox to work with 3D in creating the tooling. 
Cox contended that it was damaged by 3D's and Rogers' alleged inability to
timely complete the contracts.  On October 31, 1997, 3D demurred to Cox's
Verified Complaint.  Rogers joined in 3D's demurrer.  3D's demurrer contended
that written, not oral, contracts governed the relationship of the parties, that
the Complaint did not adequately plead the required elements of fraud, that the
Complaint failed to state a claim for Negligent Misrepresentation, Conversion,
and Money Had and Received, and that Accounting was not actually a cognizable
cause of action, but an equitable remedy.

     After a hearing on December 2, 1997, the Court sustained 3D's demurrer,
ordering Cox to file an amended complaint.  On January 29, 1998, Cox filed a
Verified Amended Complaint, asserting causes of action for Breach of Written
Contract, Fraud, and Negligent Misrepresentation.  The Verified Amended
Complaint also stated identical claims against Rogers.   The Company believes
that the case has no merit and intends to vigorously defend this action.

     PATENT OPPOSITION AND INVALIDATION PROCEEDINGS.  The Company has received 6
patents in Japan and one other application has been examined by the Japanese
Patent Office and subsequently published for opposition.  One opposition was
submitted against this application.  The Company has responded to the
opposition.  Based on this opposition and 3D's response, the Japanese Patent
Office may require the Company to further defend or modify this application
before granting any patent thereon or may even finally reject the application. 
Furthermore, one of the six patents has had three invalidation trials filed
against it.  These invalidation trials are ongoing.  The Company has responded
to two of these trials and it is anticipated that the Company will respond to
the third trial in the coming months.  These trials may result in maintaining
the patent with present or modified protection or may result in revocation of
the patent.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

     The following discussion contains forward-looking statements that involve
risks and uncertainties.  The Company's future results could differ materially
from those discussed here.  Factors that could cause or contribute to such
differences include, but are not specifically limited to: the ability to develop
and introduce cost effective new products in a timely manner; developments in
current or future litigation; the Company's ability to successfully manufacture
and sell significant quantities of equipment on a timely basis; as well as the
other risks detailed in this section and in the sections entitled Results of
Operations and Liquidity and Capital Resources and Cautionary Statements and
Risk Factors.

OVERVIEW

     The Company develops, manufactures and markets worldwide solid imaging
systems designed to rapidly produce physical objects from the digital output of
solid or surface data from computer aided design and manufacturing ("CAD/CAM")
and related computer systems.  The Company's systems include SLA Industrial
Systems (SLA) and Solid Object Printers.   The SLA Industrial Systems use the
Company's proprietary stereolithography technology,  a solid imaging process
whereby a laser beam exposes and solidifies successive layers of photosensitive
resin until the desired object is formed to precise specifications in hard
plastic.  The Solid Object Printers, sold as the Actua 2100 and ThermoJet,
utilize hot melt ink jetting technology to print models in successive layers
with a special thermopolymer material.  These objects can be used for concept
models, engineering prototypes, patterns and masters for molds and other
applications.

     The Company has sold over 1,200 systems since 1988, and its customers
include major corporations in a broad range of industries including
manufacturers of automotive, aerospace, computer, electronic, consumer and
medical products.  The Company's revenues are generated by product and service
sales.  Product sales are comprised of the sale of systems and related
equipment, materials, software, and other component parts, as well as rentals of
systems.  Service sales include revenues from a variety of on-site maintenance
services, customer training, services provided by the Company's Technology
Centers and 3D Keltool licensing and support services.

1998 COMPARED TO 1997

SALES.  Sales in 1998 were $98.1 million, an increase of 8.7% over the $90.3
million recorded during 1997.

Product sales in 1998 increased $6.3 million or 10.6% to $65.4 million compared
to $59.1 million in 1997.  The dollar increase was primarily due to improved
average selling prices in Europe as a result of the EOS acquisition, and an
improved product mix as the demand for the Company's Millennium series 3500 and
5000, launched in late 1997, caused a shift in the mix of customer orders to
more of these high end SLA systems.  The Company sold a total of 222 systems in
1998 compared to 274 systems in 1997.  Orders for the Company's systems in 1998
(compared to 1997) increased significantly in Europe and were up in the U.S.,
while orders were down slightly in Asia Pacific.

In 1997, the U.S. market was impacted by inefficiencies caused by changes in the
domestic sales organization.


                                     Page 24
<PAGE>

The Company believes that system sales may fluctuate on a quarterly basis as a
result of a number of factors, including the acceptance and reliability of new
products in the market, status of world economic conditions, fluctuations in
foreign currency exchange rates, impact of changing technology, and the timing
of product shipments.  Due to the high price of certain systems, the
acceleration or delay of a small number of shipments from one quarter to another
can significantly affect the results of operations for the quarters involved.

Service sales in 1998 increased $1.6 million, or 5.1%, compared to 1997,
primarily as a result of increased maintenance revenues due to the larger
installed base of SLA systems in the U.S. and Europe.  This increase was offset,
in part, by a decline in revenues from the Company's Technology Centers.

COST OF SALES.  Cost of sales decreased to $55.5 million or approximately 56.6%
of sales in 1998 compared to $57.2 million or 63.4% of sales in 1997.

Product cost of sales as a percentage of product sales improved in 1998,
decreasing from 60.0% in 1997 to 51.2% in 1998.  This improvement was due
primarily to increased average selling prices in Europe, an improved product mix
to a higher end SLA systems, continued reductions in overall cost of factory
operations, and revenues related to certain royalty bearing lease agreements. 
In addition, 1997 included inventory adjustments totaling approximately $1.8
million that were primarily associated with the transition to new products, the
EOS acquisition, and field service inventories.

The Company believes that the benefits from improved average selling prices have
been optimized and will not increase further and competitive pricing initiatives
may result in lower average selling prices over time.  In addition, while the
Company expects reductions in factory costs to continue, the rate of reductions
may decrease.  These are forward looking statements, and as such, are subject to
risks and uncertainties.  For example, the acceptance and reliability of new
products in the market may result in inventory adjustments and increased factory
costs, and the impact of competition on changing economic conditions in the U.S.
and Europe may materially impact average selling prices.  In addition, there can
be no assurance that the Company will not experience significant quarterly
fluctuations due to the impact of mix of products, channels, and markets, or
that a changing mix over time will not result in a higher average percentage of
cost of sales to product sales.

Service cost of sales as a percentage of service sales decreased to 67.5% in
1998 from 69.9% in 1997 primarily due to the fact that 1997 included certain
hardware upgrade costs associated with the Company's NT version system software.
In addition, field service costs are improving as a result of increased
reliability of the Company's systems.  This is offset, in part, by declining
revenues in the Company's Technology Center.  While the Company expects to see
continued improvements in field service costs, the Company does not expect an
improvement in Technology Center revenues in the first half of 1999.  As such,
service cost of sales as a percentage of sales are not expected to decrease
further in 1999.  This is a forward looking statement, however, and as such
includes certain risks.  For example, the reliability of new products in the
market or a further decline in the demand or market pricing of Technology Center
services, could cause an increase in service costs of sales. 

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative ("SG&A") improved, as a percent of sales, to 31.0% of total sales
in 1998 from 32.9% in 1997.  SG&A expense increased $.8 million or 2.7% from
1998 to 1997, due primarily to increased commissions and sales bonuses resulting
from higher sales and profits, and costs related to expanded marketing and
communications programs, and increased bad debt costs due to conditions in the
service bureau customer base, most notably the Chapter 7 filing of P2 Holdings
dba Plynetics Express, one of the largest service bureaus in the U.S.  With the
introduction of new products, the Company expects an increase in SG&A expenses
in 1999 as compared to 1998, while SG&A expenses as a percent of sales is
expected to continue to decline.  However, this is a forward looking statement
and, as such, includes certain risks.  For example, the acceptance and
reliability of new products, or changing economic conditions in the U.S. and
Europe may materially impact total sales for any particular period, and result
in an increase in SG&A expenses as a percentage of sales.

RESEARCH AND DEVELOPMENT EXPENSES.  Research and development ("R&D") expenses in
1998 decreased approximately $1.6 million or approximately 14.2% compared to
1997.  The decrease in R&D expenses in 1998 was due primarily to the fact that
1997 included a write-off of acquired in-process technology valued at
approximately $2,100,000 in connection with the EOS acquisition (see Note 7 of
Notes to Consolidated Financial Statements) offset in part by increased
personnel and experimental material costs related to certain development
projects.  Based on the Company's historical expenditures related to research
and development and its current development goals, the Company anticipates for
the foreseeable future, research and development expenses will be approximately
ten percent of sales.  However, this is a forward-looking statement and, as with
any such statement, is subject to uncertainties.  For example, if total 


                                     Page 25
<PAGE>

sales of the Company for any particular period do not meet the anticipated 
sales of the Company for that period, research and development expenses as a 
percentage of sales may exceed ten percent.

OPERATING INCOME (LOSS).  Operating income in 1998 was 2.8% of total sales
compared to an operating loss of (8.4%) of total sales in 1997.  The improvement
in 1998 is primarily attributable to inventory write offs and costs associated
with the EOS acquisition included in 1997, improved average selling prices and
product mix, and improving product and service cost of sales, as described
above.

OTHER INCOME AND EXPENSES.  Interest income decreased by $.3 million in 1998
compared to 1997.  This decrease is primarily due to lower average income on
leases and investment balances.  Interest and other expense increased by $.1
million in 1998 compared to 1997 due to various non operating expenses.

PROVISION FOR INCOME TAXES (BENEFITS).  For 1998 the Company's tax expense was
$1.1 million or 33.1% of pre-tax income (loss), compared to a tax benefit of
$2.2 million in 1997.  The Company's effective tax rate was favorably impacted
from statutory rates primarily as a result of utilizing research and
experimentation tax credits and the effects of foreign operations.

1997 COMPARED TO 1996

SALES.  Sales in 1997 were $90.3 million, an increase of 13% over the $79.6
million recorded during 1996.

Product sales in 1997 increased $5.9 million or 11% to $59.1 million compared to
$53.2 million in 1996.  The dollar increase was primarily the result of
increased shipments of SLAs in both the U.S. and Europe.  The Company sold a
total of 161 SLA systems and a total of 113 Actua 2100 systems in 1997.  In
1996, the Company sold 151 SLAs and 6 Actua 2100's.  Orders for the Company's 
systems in 1997 (compared to 1996) increased in both Europe and Asia Pacific but
declined in the U.S. market and total systems backlog at the end of 1997 was
lower than the end of 1996.

The Company believes that the decline in the U.S. orders in 1997 (when compared
to 1996) was due primarily to the inefficiencies caused by the recent changes in
the domestic sales organization from a strategy of utilizing independent sales
representatives (primarily in the machine tool industry) to a direct sales
force. The Company completed its staffing of its domestic sales organization
during the second half of 1997.  

Service sales in 1997 increased $4.7 million, or 18%, compared to 1996,
primarily as a result of increased maintenance revenues due to the larger
installed base of SLA systems in the U.S. and Europe.

COST OF SALES.  Cost of sales increased to $57.2 million or 63% of sales in 1997
compared to $41.8 million or 52% of sales in 1996.

Product cost of sales as a percentage of product sales increased to 60% in 1997
compared to 47% in 1996.  The increase in 1997 was primarily the result of
greater discounting of system sales in 1997 due to competition, the sales mix of
the Company's products as well as the channels and markets in which the Company
distributes its products.  In addition, the Company recorded inventory
adjustments totaling approximately $1.8 million, or 5 percentage points of the
increase, that were primarily associated with the transition to our new
generation of products announced in the third quarter of 1997, the EOS
acquisition and field service inventories.

Service cost of sales as a percentage of service sales increased to 70% in 1997
compared to 64% in 1996, primarily as a result of certain hardware upgrades
afforded SLA-500 customers with software maintenance contracts due to the
Company's new NT version system software, increased parts costs under the
Company's field maintenance contracts  and the effect of certain inefficiencies
attributable to the Company's Keltool operations which were acquired in
September 1996.  

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative ("S,G&A") expenses increased $5.0 million or 20% in 1997 compared
to 1996, primarily as a result of approximately $2.0 million of non-recurring
expenses for severance benefits and other costs related to restructuring plans
designed to reduce costs and improve operating results and the expanded
sales and marketing program in Europe and the U.S.    

RESEARCH AND DEVELOPMENT EXPENSES.  Research and development ("R&D") expenses in
1997 increased approximately $3.3 million of 43% compared to 1996.  The increase
in R&D expenses in 1997 was primarily the result of the write-off during the
third quarter of 1997 of acquired in-process technology valued at approximately
$2,100,000 in connection with the EOS acquisition (see Note 7 of Notes to
Consolidated Financial Statements) and increased personnel costs and
experimental material related to certain development projects. 

OPERATING INCOME (LOSS).  Operating loss  in 1997 was (8.4%) of total sales
compared to operating income of 6.8% of total sales in 1996.  The decrease in
percentage of operating income to total sales in 1997 was primarily attributable
to increases in cost of sales (both products and services) in 1997 and the
increased S,G&A and R&D expenses, as described above.

OTHER INCOME AND EXPENSES.  Interest income decreased to $1.2 million in 1997
from $1.5 million in 1996, primarily as a result of the lower investment
balances due to cash used for operating activities and investment activities
partially offset by interest income from lease receivables.  Interest expense
increased to $.4 million in 1997 from $.1 million in 1996 primarily as a result
of the Company's financing of its Colorado facility which was effected August
20, 1996.  

PROVISION FOR INCOME TAXES (BENEFITS).  For 1997 the Company's tax benefit was
$2.2 million or 32% of pre-tax income (loss), compared to a tax expense of $2.2
million in 1996.

FOREIGN OPERATIONS

     International sales accounted for  33.8%, 41.5% and 44.1% of total sales in
1996, 1997 and 1998, respectively.  For information with respect to allocation
of sales among the Company's foreign operations, see Note 17 of Notes to
Consolidated Financial Statements.

     The effects of the Asian currency crisis affected the growth of the Asian
market, and sales for 1998 were approximately equal to 1997 levels.  The
European operations continued to grow and the Company opened an office in
Barcelona, Spain to address the growth of the Southern European market.

     To date, the Company has not entered into hedging transactions to protect
against changes in foreign currency exchange rates.

- -------------------
(1)  Includes $722,000 of restricted cash at December 31, 1996. 


     Net cash provided by (used for) operating activities in 1996, 1997, and
1998 was $(7.0) million, $(5.0) million and $7.6 million, respectively.  The
positive cash flow from operations in 1998 was comprised primarily of net income
of $2.1 million adjusted for non-cash items such as amortization and
depreciation in the amount of $5.8 million.

     Net cash used for investing activities in 1998 totaled $4.2 million and was
primarily the result of an increase in property and equipment relating primarily
to increased demonstration equipment due to new products, the purchase of
computers and manufacturing equipment required for expansion, and an increase in
license and patent costs. 

     Net cash used for financing activities in 1998, totaling $.9 million was
the result of the Company buying back 200,000 of its own shares in the open
market, for approximately $1.4 million, partially offset by proceeds from the
exercise of stock options and warrants.

     In August 1998, the Company extended its credit facility with Silicon
Valley Bank ("SVB") (the "Credit Facility"). Under the terms of the agreement,
which remains in effect through August 18, 1999, the Company can borrow from SVB
up to $10,000,000, at the bank's prime interest rate.  The Credit Facility
contains certain financial covenants including the maintenance of certain
financial ratios, working capital, tangible net worth as well as covenants
limiting mergers, acquisitions, recapitalizations, dividends, loans to others,
and hypothecation of assets or corporate guarantees.  As of December 31, 1998,
the Company has yet to utilize the Credit Facility.

     On May 6, 1997, the Company announced that its board of directors had
authorized the Company to buy up to 1.5 million of its shares in the open market
and through private transactions.  During 1997, the Company purchased 25,000 of
its own shares for approximately $165,000.  During the first quarter of 1998,
the Company purchased 200,000 of its own shares for approximately $1.4 million. 
The Company may continue to acquire additional shares from time to time at
prevailing market prices, at a rate consistent with the combination of corporate
cash flow and market conditions.
     
     The Company believes that funds generated from operations, existing working
capital and its current line of credit will be sufficient to satisfy its
anticipated operating requirements for at least the next twelve months.  From
time to time the Company considers the acquisition of businesses, products or
technologies complimentary to the Company's current business.  Should the
Company decide to pursue such a transaction, and it exceeds funds available from
current operations, the Company may require additional funds. 

     There were no significant inflationary trends that impacted the Company in
1998.

     The Company has established a team to address the issues raised by the
introduction of the Single European Currency ("Euro") for initial implementation
as of January 1, 1999 and during the transition period through January 1,
2002.  The Company expects that its internal systems that will be affected by
the initial introduction of the Euro will be Euro capable by the third quarter
1999 and does not expect the costs of system modifications to be material.  The
Company does  not presently expect that the introduction and use of the Euro
will materially affect the Company's foreign exchange or 


                                     Page 29
<PAGE>

will result in any material increase in costs to the Company.  While the Company
will continue to evaluate the impact of the Euro introduction over time, based
on currently available information, management does not believe that the
introduction of the Euro currency will have a material adverse impact on the
Company's financial condition or overall trends in results of operations.  

YEAR 2000 COMPLIANCE. Computer-based systems that require date/time calculations
to operate correctly are subject to miscalculations and system failures on and
after the year 2000. This is known as the Y2K problem. The Y2K problem affects
systems that were developed to accept two digit entries for the year in the date
code field. After midnight on December 31, 1999, these systems may recognize a
date using '00' as the year 1900 rather than the year 2000. Another known issue
is that many systems will not recognize the year 2000 as a leap year.   The Y2K
problem is pervasive in that it goes beyond internal systems to involve supply
and distribution chains and extends to both public and private infrastructure
services including water, gas, electricity, transportation and communications.

     The Company believes its current products are Year 2000 compliant.  In
addition, the Company has been evaluating all products sold since inception for
Year 2000 readiness, and is providing the results of the analysis and potential
impacts and resolutions to its customers. Current information on the Company's
Y2K status can be found on the Internet at: http://www.3dsystems.com.  In the
fourth quarter of 1998, the Company completed the evaluation of substantially
all its products.  The necessary upgrade pathways to its customers will be
completed by the end of the first quarter of 1999. The Company plans to have the
actual software patches that may be required available for customers by the
third quarter 1999. The Company believes that all products will meet basic
functionality requirements, however, since all specific customer situations and
uses cannot be anticipated, 3D Systems may see an increase in warranty and other
claims as a result of the Year 2000 transition.  For these reasons, the impact
of customer claims could have a material adverse impact on the Company's results
of operations or financial condition.
                              
     The Company is continuing the comprehensive evaluation of its internal
business systems.  Certain critical infrastructure and information systems are
being upgraded to meet Year 2000 requirements.  These upgrades will also have
the benefit of meeting the Euro currency requirements and expanding the
capability of the Company.  At the completion of these current projects, the
Company will be conducting transaction testing to evaluate compliance of the
overall system infrastructure. To date, the Company has substantially completed
the risk analysis on all U.S.-based systems.  During the fourth quarter 1998,
the Company has completed substantially all infrastructure upgrades in the U.S.
as well as certain European operations.  The Company plans to complete the risk
analysis of foreign operations in the first quarter of 1999, as well as
implement the Year 2000 compliance upgrade of its core ERP system.  The Company
believes that the vast majority of Y2K-related issues with respect to internal
business systems will be inventoried, analyzed, and resolved by the third
quarter 1999, and that certification and/or testing will be completed by the end
of the third quarter 1999.

     Since the majority of the efforts related to Year 2000 Compliance are being
performed by internal resources, and are part of an overall plan to upgrade the
overall capability of the Company and meet Euro currency requirements, there is
no exact program budget or cost associated exclusively with Year 2000 efforts. 
The Company believes costs related to Year 2000 compliance are less than
$750,000, and estimates that costs for the worldwide program will not exceed
$1.5 million.  As stated in the Liquidity and Capital Resources section, the
Company believes that funds generated from operations will be sufficient to
satisfy Year 2000 compliance costs.
                         
     3D Systems is continuing to review its critical suppliers to determine that
the suppliers' operations and the products and services they provide are Year
2000 compliant.  The Company has completed a survey of key  suppliers and
evaluated their individual risk potential as well as the risk potential of their
suppliers. In addition, the Company has conducted site surveys of certain
critical or sole source suppliers.  The Company will begin evaluating next
tier suppliers in the first quarter 1999.  Currently, the Company's contingency
strategies include seeking alternative sources of supplies or acquiring
sufficient material to support the Company's operations for the first half of
2000.  Though the Company believes it has sufficient alternatives and liquidity
to meet this contingency strategy, such failures of suppliers remain a
possibility and could have a material adverse impact on the Company's results of
operations or financial condition.

     Year 2000 compliance is an issue for virtually all businesses, whose
computer systems and applications may require significant hardware and software
upgrades or modifications.  Companies owning and operating such systems may plan
to devote a substantial portion of their capital spending to fund such upgrades
and modifications and divert spending away from capital manufacturing equipment
spending.  Such changes in customers' spending patterns could have a material
adverse impact on the Company's sales, operating results or financial condition.

                        REPORT OF INDEPENDENT ACCOUNTANTS




To the Stockholders and Board of Directors
3D Systems Corporation

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, stockholders' equity, cash flows and
comprehensive income present fairly, in all material respects, the financial
position of 3D Systems Corporation and its subsidiaries (the "Company") at
December 31, 1997 and 1998, and the consolidated results of their operations and
their cash flows for each of the three years in the period ended December 31,
1998, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                             3D SYSTEMS CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  Years ended December 31, 1996, 1997 and 1998


(1)      ORGANIZATION AND BUSINESS

         3D Systems Corporation (the "Company") develops, produces and markets
         Stereolithography Apparatus ("SLA") and Actua 2100 systems and related
         materials, parts and services. 3D Systems, Inc., a California based
         corporation ("3D California"), an indirect wholly-owned subsidiary of
         the Company, directly and through its subsidiaries, conducts
         substantially all of the Company's business.

(2)      SIGNIFICANT ACCOUNTING POLICIES

         (a)      PRINCIPLES OF CONSOLIDATION

                  The consolidated financial statements include the accounts of
                  the Company and its wholly-owned subsidiaries. All
                  intercompany accounts and transactions have been eliminated in
                  consolidation.

                  Certain reclassifications have been made to the prior year
                  consolidated financial statements to conform to the current
                  year presentation.

         (b)      SALES AND CONCENTRATION OF CREDIT RISK

                  Revenues from the sale of the Company's systems and related
                  products are recognized upon shipment and satisfaction of
                  Company obligations, if any. The Company provides end users
                  with up to one year of maintenance and warranty services, and
                  defers a portion of its revenues for these costs at the time
                  of sale based on the relative fair value of such services.
                  After the initial maintenance period, the Company offers these
                  customers optional maintenance contracts; revenue related to
                  these contracts is deferred and recognized ratably over the
                  period of the contract. To date, the Company has not
                  experienced any significant warranty claims or product
                  returns.

                  Credit is extended based on an evaluation of each customer's
                  financial condition. To reduce credit risk in connection with
                  sales of SLA systems, the Company may, depending upon the
                  circumstances, require significant deposits prior to shipment
                  and may retain a security interest in the SLA systems until
                  fully paid. The Company often requires international customers
                  to furnish letters of credit.

                  The Company invests its excess cash in interest bearing
                  deposits with major banks, commercial paper and money market
                  funds. Although a majority of the cash accounts exceed the
                  federally insured deposit amount, management does not
                  anticipate non-performance by the financial institutions.
                  Management reviews the stability of these institutions on a
                  periodic basis.

         (c)      CASH AND CASH EQUIVALENTS

                  The Company considers all highly liquid debt instruments
                  purchased with an original maturity of three months or less to
                  be cash equivalents. The carrying value of these instruments
                  approximates market value because of their short maturity.

         (d)      INVESTMENTS

                  The Company's short-term investments are classified as held to
                  maturity and recorded at amortized cost under the provisions
                  of Statement of Financial Accounting Standards (SFAS) No. 115.

                             3D SYSTEMS CORPORATION
              Notes to Consolidated Financial Statements, Continued 
                     Years ended December 31, 1996, 1997 and 1998


         (e)      LEASES

                  At the inception of a lease, the gross lease receivable, the
                  reserve for potential losses, the estimated residual value of
                  the leased equipment and the unearned lease income are
                  recorded. The unearned lease income represents the excess of
                  the gross lease receivable plus the estimated residual value
                  over the cost of the equipment leased and is recorded in
                  deferred revenue.

         (f)      INVENTORIES

                  Inventories are stated at the lower of cost (determined by the
                  first-in, first-out method) or market value.

         (g)      PROPERTY AND EQUIPMENT

                  Property and equipment is carried at cost and depreciated on a
                  straight-line basis over the estimated useful lives of the
                  related assets, generally three to five years. Leasehold
                  improvements are amortized on a straight-line basis over their
                  estimated economic useful lives, or the lives of the leases,
                  whichever is shorter. Realized gains and losses are recognized
                  upon disposal or retirement of the related assets and are
                  reflected in results of operations. Repair and maintenance
                  charges are expensed as incurred.

         (h)      LICENSES AND PATENT COSTS

                  Licenses and patent costs are being amortized on a
                  straight-line basis over their estimated useful lives, which
                  are approximately eight to seventeen years.

         (i)      LONG TERM ASSETS

                  The carrying value of long term assets is periodically
                  reviewed by management, and impairment losses, if any, are
                  recognized when the expected nondiscounted future operating
                  cash flow derived from such assets are less than their
                  carrying value.

         (j)      CAPITALIZED SOFTWARE COSTS

                  Certain software development and production costs are
                  capitalized upon a product's reaching technological
                  feasibility. As of December 31, 1997 and 1998, the Company had
                  cumulatively capitalized software development costs of
                  $3,418,058 and $3,837,880, respectively. Costs capitalized in
                  1997 and 1998 were $501,394 and $419,822, respectively.
                  Amortization of software development costs begins when the
                  related products are available for market. Amortization
                  expense amounted to $509,327, $495,127 and $503,804 for 1996,
                  1997 and 1998, respectively, based on the straight-line method
                  using estimated useful lives of two years. Net capitalized
                  costs aggregated $530,991 and $447,009 at December 31, 1997
                  and 1998, respectively, and are included in other assets in
                  the accompanying consolidated balance sheets.

         (k)      FOREIGN CURRENCY TRANSLATION

                  The assets and liabilities of the Company's foreign operations
                  are translated at the end of the period exchange rates;
                  revenues and expenses are translated at the average exchange
                  rates prevailing during the period. The effect of the
                  unrealized exchange rate fluctuations on translating foreign
                  currency assets and liabilities into U.S. dollars are
                  accumulated as a separate component of stockholders' equity.
                  Gains and losses resulting from foreign currency transactions
                  are included in operations during the period realized. The
                  aggregate foreign exchange gains (losses) included in
                  operations were $8,773, ($478,643) and $275,903 for 1996, 1997
                  and 1998, respectively. To date, the Company has not entered
                  into hedging transactions to protect against changes in
                  foreign currency exchange rates.

                  Research and development costs are expensed as incurred.

         (m)      EARNINGS PER SHARE

                  Net income (loss) per common share is computed by dividing net
                  income (loss) by the weighted average number of shares of
                  common stock outstanding during the period. Net income (loss)
                  per common share assuming dilution is computed by dividing net
                  income (loss) by the weighted average number of shares of
                  common stock outstanding plus the number of additional common
                  shares that would have been outstanding if all dilutive
                  potential common shares had been issued. Potential common
                  shares related to stock options and stock warrants are
                  excluded from the computation when their effect is
                  antidilutive.

         (n)      ADVERTISING COSTS

                  Advertising costs are expensed as incurred. Advertising
                  expenses were approximately $1,955,000, $2,946,000 and
                  $2,261,000 for the years ended 1996, 1997 and 1998,
                  respectively.

         (o)      ESTIMATES

                  The preparation of financial statements in conformity with
                  generally accepted accounting principles requires management
                  to make estimates and assumptions that affect the reported
                  amounts of assets and liabilities and disclosure of contingent
                  assets and liabilities at the dates of the financial
                  statements and the reported amounts of revenues and expenses
                  during the reporting periods. Actual results could differ from
                  those estimates.

         (p)      STOCK-BASED COMPENSATION

                  The Company grants stock options for a fixed number of shares
                  to employees with an exercise price equal to the fair value of
                  the shares at the date of grant. The Company accounts for
                  stock option grants in accordance with APB Opinion No. 25,
                  "Accounting for Stock Issued to Employees."

         (q)      INCOME TAXES

                  The Company accounts for income taxes using the liability
                  method as required by SFAS No. 109, "Accounting for Income
                  Taxes." Under SFAS No. 109, deferred income taxes are
                  determined based on the differences between the financial
                  statement and tax bases of assets and liabilities, using
                  enacted tax rates in effect for the year in which the
                  differences are expected to reverse. Valuation allowances are
                  established when necessary to reduce deferred tax assets to
                  the amounts expected to be realized.

         (r)      COMPREHENSIVE INCOME

                  In 1998, the Company adopted SFAS No. 130, "Reporting
                  Comprehensive Income," and accordingly has included a separate
                  Statement of Comprehensive Income. Comprehensive income
                  generally represents all changes in shareholders' equity
                  during the period except those resulting from investments by,
                  or distributions to, shareholders.

         (s)      SEGMENT INFORMATION

                  In 1998, the Company adopted SFAS No. 131, "Disclosures about
                  Segments of a Business Enterprise and Related Information."
                  SFAS No. 131 supersedes SFAS No. 14, "Financial Reporting for
                  Segments of a Business Enterprise," replacing the "industry
                  segment" approach with the "management" approach. The
                  management approach designates the internal organization that
                  is used by management for making operating decisions and
                  assessing performance as the source of the Company's
                  reportable segments. SFAS No. 131 also requires disclosures
                  about products and services, geographic areas, and major
                  customers. The adoption of SFAS No. 131 did not affect results
                  of operations or financial position but did affect the
                  disclosure of segment information (Note 17).

(3)      LEASES

         The Company provides lease financing for qualified customers. The
         leases are accounted for as sales-type leases where the present value
         of minimum lease payments, net of costs, are recorded as sales. The
         components of lease receivables are as follows:

              Notes to Consolidated Financial Statements, Continued 
                     Years ended December 31, 1996, 1997 and 1998

         (a)      In 1997 and 1998, the Company incurred and capitalized
                  $330,561 and $643,405, respectively, of costs to develop and
                  extend patents in the United States, Japan, Europe and certain
                  other countries and expensed previously developed capitalized
                  patent costs of $392,862 and $364,726, respectively.

         (b)      Effective January 5, 1990, 3D California acquired the patents
                  for stereolithography technology from UVP, Inc. ("UVP") in
                  exchange for $9,075,000, $500,000 of which was paid in cash
                  and $350,000 in offsets of costs incurred by the Company on
                  behalf of UVP. The initial payment and offsets ($850,000) have
                  been capitalized and are being amortized over the remaining
                  life of patents (approximately 4 years at December 31, 1998).
                  The agreement further provided for payment deferrals during
                  1990 through 1992 aggregating $950,000. The Company accrues
                  royalty expense based upon the sales levels of SLA machines
                  under the agreement, up to a maximum of $8,225,000. In 1996,
                  1997 and 1998, royalty expense aggregated $674,182, $667,904,
                  and $710,968 respectively, and is included in cost of
                  sales-products in the accompanying consolidated statements of
                  operations. Royalty obligations at December 31, 1997 and 1998
                  are $1,612,450 and $1,745,267 respectively, and are included
                  in the accompanying consolidated balance sheets. In the event
                  the Company licenses the acquired technology to a third party,
                  the Company is required to pay UVP 50% of the royalties it
                  receives up to an aggregate maximum of $8,225,000, including
                  the Company's payments based on sales levels of its SLA
                  machines. UVP has retained a security interest in the
                  purchased technology until the purchase price is fully paid.

         (c)      The excess of the cost of the Company's investment in 3D
                  California over the related underlying equity in the net
                  assets of the subsidiary at the date of acquisition
                  ($2,011,707) has been attributed to the licenses and patents
                  of 3D California and is being amortized on the same basis as
                  the underlying licenses and patents.


7)       ACQUISITIONS

         (a)      On September 9, 1996, 3D California, purchased substantially
                  all of the assets and business operations of Keltool, Inc.
                  ("Keltool"), of St. Paul, Minnesota, a Company which produces
                  steel tooling for plastic injection molding machines based on
                  a patented process using sintered powdered steel.
                  Additionally, acquired in-process technology was previously
                  expensed. The purchase price paid by the Company included
                  $1,740,000 payable in cash (of which $875,000 was paid on
                  September 9, 1996 and $865,000 paid on October 10, 1996), the
                  assumption of certain liabilities ($13,000) and the value of
                  warrants to purchase 50,000 shares of the Company's common
                  stock at an exercise price of $14.75 per share ($193,000). The
                  warrants were issued at fair market value and expire on
                  September 9, 1999.

                  The allocation of the purchase consideration for Keltool was

                  Years ended December 31, 1996, 1997 and 1998


         (b)      On September 22, 1997, the Company completed the acquisition
                  of the rapid prototyping "Stereos" product line assets and
                  business from EOS GmbH of Germany, formerly 3D's major
                  European competitor. Under the terms of the agreement, 3D paid
                  $3.25 million, subject to certain adjustments based on final
                  determination of the value of the assets acquired, issued a
                  warrant to buy 150,000 of 3D's common shares at $8.00 per
                  share exercisable within the three year period following the
                  closing (valued at $727,000), and granted EOS exclusive
                  licenses to 3D patents related to laser sintering.
                  Additionally, the Company agreed to settle all pending patent
                  infringement and unfair competition lawsuits brought against
                  EOS and an EOS customer.

                  In accordance with the purchase method of accounting, the
                  purchase price has been allocated to the underlying assets and
                  liabilities based on their respective fair values at the date
                  of acquisition. The in-process research and development was
                  expensed in the quarter ended September 26, 1997 as a
                  nonrecurring cost after determining that it had not reached
                  technological feasibility and for which there is no
                  alternative future use.

                  The total purchase price is estimated at $4,075,000 and was
                  allocated as follows:

(8)      NOTE PAYABLE

         In August 1998, the Company extended its credit facility with Silicon
         Valley Bank ("SVB") (the "Credit Facility"). Under the terms of the
         agreement, which remains in effect through August 18, 1999, the Company
         can borrow from SVB up to $10,000,000, at the bank's prime interest
         rate. The Credit Facility contains certain financial covenants
         including the maintenance of certain financial ratios, working capital,
         tangible net worth as well as covenants limiting mergers, acquisitions,
         recapitalizations, dividends, loans to others, and hypothecation of
         assets or corporate guarantees. As of December 31, 1998, the Company
         has yet to utilize the Credit Facility.

(11)     LONG-TERM DEBT

         On August 20, 1996, the Company completed a $4.9 million variable rate
         industrial development bond financing of its Colorado facility.
         Interest on the bonds are payable monthly (the interest rate at
         December 31, 1998 was 4.20%). Principal payments are payable in
         semi-annual installments beginning in February 1997 through August
         2016. The bonds are collateralized by an irrevocable standby letter of
         credit issued by Norwest Bank Minnesota, N.A. which is further
         collateralized by the building and related machinery and equipment as
         well as a standby letter of credit issued by SVB in the amount of
         approximately $1.4 million. The terms of the letters of credit require
         the Company to maintain specific levels of minimum tangible net worth,
         debt to equity ratio and quick ratio. Annual maturities of long-term
         debt are as follows:

(12)     STOCKHOLDERS' EQUITY AND STOCKHOLDERS' RIGHTS PLAN

         (a)      On May 23, 1996, the Company's stockholders approved the 1996
                  Stock Incentive Plan (the "1996 Plan") and the 1996 Stock
                  Option Plan for Non-Employee Directors (the "Director Plan").
                  The maximum number of shares of Common Stock that may be
                  issued pursuant to options granted under the 1996 Plan and
                  Director Plan is 1,300,000 and 200,000, respectively. Granting
                  of options under both plans expire on March 21, 2006. The 1996
                  Plan also provides for "reload options", which are options to
                  purchase additional shares if a grantee uses already-owned
                  shares to pay for an option exercise. The Company also has a
                  1989 Plan in which options for substantially all common shares
                  have been previously issued. The 1989 Plan expires in 1999
                  unless terminated earlier by the Board of Directors. The
                  option price per share under all plans is equal to the fair
                  market value on the date of grant. The vesting and exercise
                  periods for all plans, except the Director Plan, are
                  determined at the discretion of the Compensation Committee of
                  the Board of Directors. The majority of options issued under
                  the 1996 Plan and the

                   Years ended December 31, 1996, 1997 and 1998


                  1989 Plan vest 25% annually, commencing one year from the date
                  of grant and expire between six and ten years from date of
                  grant. Under the Director Plan, each non-employee director
                  ("outside director") of the Company will automatically be
                  granted annually non-statutory stock options to purchase 7,500
                  shares of Common Stock. Each option issued under the Director
                  Plan vests in equal annual installments over a three year
                  period beginning on the first anniversary and expires ten
                  years from the date of grant. Prior to the adoption of the
                  Director Plan, each outside director was automatically granted
                  annually non-statutory stock options to purchase 3,333 shares
                  of Common Stock under the 1989 Plan, as amended, beginning in
                  1993.

              Notes to Consolidated Financial Statements, Continued 
                     Years ended December 31, 1996, 1997 and 1998


                  As of December 31, 1998, options for 120,763 shares, 117,500
                  shares and 4 shares of Common Stock were available for grant
                  under the 1996 Plan, 1996 Director Plan and 1989 Plan,
                  respectively (238,267 shares in the aggregate). The 1996 Plan
                  and 1989 Plan also provide for the issuance of Stock
                  Appreciation Rights (SARs) and Limited Stock Appreciation
                  Rights (LSARs). As of December 31, 1998, no SARs or LSARs have
                  been issued.

         (b)      In December 1995, the Company's Board of Directors adopted a
                  Shareholders Rights Plan (the "Plan"). Under the provisions of
                  the Plan, the Company distributed to its stockholders, rights
                  entitling the holders to purchase one-hundredth of a share of
                  Series A Preferred Stock for each share of Common Stock then
                  held at an exercise price of $75. Upon the occurrence of
                  certain "triggering events," each right entitles its holder to
                  purchase, at the rights then-current exercise price, a number
                  of shares of common stock of the Company having a market value
                  equal to twice the exercise price. A triggering event occurs
                  ten days following the date a person or group (other than an
                  "Exempt Person"), without the consent of the Company's Board
                  of Directors, acquires 15% or more of the Company's common
                  stock or upon the announcement of a tender offer or an
                  exchange offer, the consummation of which would result in the
                  ownership by a person or group of 15% or more of the Company's
                  common stock. An Exempt Person includes Ciba Specialty
                  Chemicals Holdings, Inc. (formerly Ciba-Geigy Limited) ("CSC
                  Holdings"), which beneficially owned approximately 15.1% of
                  the issued and outstanding common stock of the Company at
                  December 31, 1996. The Plan permits CSC Holdings to increase
                  its ownership position in the Company up to 28.7% of the
                  issued and outstanding common stock of the Company without
                  losing its status as an Exempt Person. The rights will expire
                  on December 3, 2005.

         (c)      On May 6, 1997, the Company announced that its board of
                  directors had authorized the Company to buy up to 1.5 million
                  of its shares in the open market and through private
                  transactions. During 1997 and 1998 the Company purchased
                  25,000 and 200,000 of its own shares for approximately
                  $165,000 and $1,375,000, respectively. The Company will
                  continue to acquire additional shares from time to time at
                  prevailing market prices, at a rate consistent with the
                  combination of corporate cash flow and market conditions.

         (d)      In the second quarter 1998, the Company established the 1998
                  Employee Stock Purchase Plan ("ESPP") to provide eligible
                  employees the opportunity to acquire limited amounts of the
                  Company's common stock. The exercise price of each option will
                  be the lesser of (I) 85% of the fair market value of the
                  shares on the date the option is granted or (II) 85% of the
                  fair market value of the shares on the last day of the period
                  during which the option is outstanding. An aggregate of
                  600,000 shares of common stock has been reserved for issuance
                  under the plan.

                  During 1998, 37,687 shares were purchased under the Company's
                  ESPP at a weighted average price of $5.11. At December 31,
                  1998 there were 562,313 shares available for future grants.
                  The weighted average fair value of ESPP shares issued in 1998
                  was $0.96.

         (e)      Pro forma information regarding net income and earnings per
                  share is required by SFAS No. 123, and has been determined as
                  if the Company had accounted for the Plans under the fair
                  value method of the Statement. The fair value of options
                  issued under the Plans was estimated at the date of grant
                  using a Black-Scholes option pricing model with the following
                  weighted average assumptions: no dividend yield, volatility
                  factor of the expected market price of the Company's common
                  stock of .60 for 1996 and 1998 and .58 for 1997, a forfeiture
                  rate of .05 for 1996 and 1998 and zero for 1997, a
                  weighted-average expected life of the options of 4.0 years for
                  1996 and 3.9 years for 1997 and 1998 and a risk-free interest
                  rate of 6.24%, 6.28% and 5.95% for 1996, 1997 and 1998,
                  respectively. For purposes of pro forma disclosures, the
                  estimated fair value of the options is amortized to expense
                  over the options' vesting period. The Company's pro forma net
                  income (loss), net income (loss) per common share and net
                  income (loss) per common share assuming dilution would
                  approximate the following:

                     Years ended December 31, 1996, 1997 and 1998

         At December 31, 1998, the Company has remaining notes receivable
         totaling $360,000 from certain executive officers of the Company
         pursuant to the Executive Long-Term Stock Incentive Plan (which was
         adopted under the 1996 Stock Incentive Plan). The original loans of
         $420,000, of which $60,000 has been repaid, were used to purchase an
         aggregate of 67,333 shares of the Company's common stock at the fair
         market value on the date of offer. These notes bear an interest rate of
         6% per annum and mature in the year 2003. The plan calls for the loans
         to be forgiven, in part or whole, if certain profitability targets are
         met. The notes receivable are shown on the balance sheet as a reduction
         of stockholders' equity.

                     Years ended December 31, 1996, 1997 and 1998


         The valuation allowance for deferred taxes relates primarily to foreign
         deferred tax assets and was decreased by $951,000 during 1998 primarily
         due to utilization of foreign net operating losses. Although
         realization is not assured, management believes it is more likely than
         not that the Company will realize the benefit of the net deferred tax
         assets. The amount of the net deferred tax asset considered realizable,
         however, could be reduced in the near term if estimates of future
         taxable income during the carryforward period are reduced.

         The components of income tax expense (benefit) for the years ended
         December 31, 1996, 1997 and 1998 are as follows:

                     Years ended December 31, 1996, 1997 and 1998


         As of December 31, 1998, the Company has net operating loss
         carryforwards for United States federal and foreign income tax purposes
         of approximately $10,324,070 and $2,395,631, respectively. The United
         States federal net operating loss carryforwards begin to expire in
         2006, and the foreign net operating loss carryforwards expire through
         2002, except for certain operating losses which do not expire. Ultimate
         utilization of these loss carryforwards is dependent on future taxable
         earnings of the Company.

         The Company has research and experimentation tax credit carryforwards
         for United States federal and state income tax purposes of $2,153,000
         and $816,000 respectively, which begin to expire 2003 through December
         31, 2007 and 2008, respectively.

         In addition, the Company has alternative minimum tax credit
         carryforwards for United States federal and state income tax purposes
         at December 31, 1998 of $311,000 and $29,000, respectively.

(16)     EMPLOYEE BENEFIT PLAN

         In 1989, 3D California adopted a defined contribution 401(k) plan (the
         "Plan") for its employees. Employees must be at least 21 years of age
         and must have at least six consecutive months of service with the
         Company to be eligible for the Plan. Participants may contribute
         between 1% and 15% of their compensation to the Plan. The Company may
         make discretionary matching contributions limited to 50% of the
         employee contribution up to a maximum of 3-1/2% of the employee's
         compensation or discretionary profit sharing contributions.
         Participants are fully and immediately vested in employee contributions
         and vest in employer contributions over a four year period. For the
         years ended December 31, 1996 and 1998 the Company accrued profit
         sharing contributions of $229,966 and $150,032, respectively. No profit
         sharing was accrued for the year ended December 31, 1997.

(17)     GEOGRAPHIC SEGMENT INFORMATION

         All of the Company's assets are devoted to the manufacture and sale of
         Company systems, together with related supplies and services. The
         Company attributes revenues to geographic areas based on shipment in
         the country of origination.

(18)     COMMITMENTS AND CONTINGENCIES

         (a)      The Company leases its facilities under noncancelable
                  operating leases expiring through December 2002. The leases
                  are generally on a net-rent basis, whereby the Company pays
                  taxes, maintenance and insurance. Leases that expire are
                  expected to be renewed or replaced by leases on other
                  properties. Rental expense for the years ended December 31,
                  1996, 1997 and 1998 aggregated approximately $1,642,000,
                  $2,575,000 and $2,354,000, respectively.

                  Minimum annual rental commitments under the leases at December
                  31, 1998 are as follows:

         (b)      3D California is a party to an agreement with Ciba Specialty
                  Chemicals Inc. ("CSC") and certain of its subsidiaries (the
                  "Photopolymer Research Agreement"), dated August 15, 1990,
                  relating to the research and development of photopolymers,
                  photopolymerizable monomers and photoinitiators for use with
                  stereolithography technology. The agreement obligates each of
                  the parties to cooperate in the development of photopolymers,
                  photopolymerizable monomers and photoinitiators. The agreement
                  provides that the parties shall deal exclusively with each
                  other in the development of stereolithographic products except
                  that: (a) 3D California may recommend to its customers
                  products produced by suppliers other than CSC in the event
                  that another supplier produces products suitable for
                  stereolithography and CSC cannot produce a product with
                  similar performance parameters, (b) 3D California may pursue
                  the development of certain products developed pursuant to the
                  agreement if CSC determines it has no capabilities or interest
                  in such products, (c) CSC may cooperate in developing
                  competing products if such products involve new fields of
                  technology in which 3D California does not have and is not
                  able within a reasonable time to develop expertise.

                  As part of the Photopolymer Research Agreement, the parties
                  have agreed that if a change in control of the Company or 3D
                  California should occur, then at the option of CSC, 3D
                  California will be required to pay CSC an amount equal to
                  CSC's "deferred research and development costs", up to $10
                  million. A "change in control" is defined to have occurred
                  only if a person, or group of related persons, becomes the
                  beneficial owner of in excess of 31.4% of the Company's
                  outstanding voting securities (such percentage to be ratably
                  increased in the event of any sale by a CSC affiliate of any
                  of its shares of the Company's shares of common stock), unless
                  approved by CSC, or its indirect nominees to the Board of
                  Directors of the Company. "Deferred Research and Development
                  Costs" means all costs incurred by CSC during the five full
                  fiscal years immediately preceding the occurrence of a change
                  in control, multiplied by two. The existence of this provision
                  may deter potential acquirers from seeking to acquire the
                  Company, or a significant interest in the equity securities of
                  the Company.

              Notes to Consolidated Financial Statements, Continued 
                     Years ended December 31, 1996, 1997 and 1998


                  In connection with the Photopolymer Research Agreement, 3D
                  California entered into a Photopolymer Distribution Agreement
                  with a subsidiary of CSC, dated as of July 1, 1990, pursuant
                  to which 3D California is the exclusive worldwide distributor
                  of photopolymers manufactured by CSC. At the request of 3D
                  California, an affiliate of CSC currently sells such
                  photopolymers in Japan to 3D California's Japanese
                  distributor. Subject to certain conditions, so long as CSC
                  provides adequate supplies, 3D California is required to fill
                  all of its requirements for its photopolymers through
                  purchases from CSC. In order to maintain its exclusive
                  distribution rights, 3D California must meet certain quotas
                  based on the dollar value of products purchased from CSC on an
                  annual basis as set forth in the agreement. 3D California has
                  in the past failed to meet quotas established under the
                  agreement and, in May 1995, 3D California and CSC mutually
                  agreed to reduce the quotas to levels which 3D California
                  believes should be commercially obtainable. Subject to certain
                  conditions, the agreement will remain in effect until June 30,
                  1997 and will continue thereafter until either party gives the
                  other six months advance notice of termination.

         (c)      On May 24, 1993, 3D Systems, Inc. and its wholly-owned German
                  subsidiary, 3D Systems GmbH (both referred to as "3D") filed a
                  patent infringement lawsuit against EOS, a European
                  competitor, seeking compensation from EOS for infringing
                  patents owned by 3D.

                  On November 2, 1994, 3D GmbH filed a patent infringement
                  lawsuit against Leopold Kostal GmbH & Co., a German customer
                  of EOS, seeking compensation from Kostal for infringing
                  patents owned by 3D, as well as an injunction barring Kostal
                  from using the EOS equipment.

                  In August 1997, these lawsuits were settled as part of an
                  agreement under which 3D also acquired the
                  stereolithography-related assets of EOS, with each of the
                  parties bearing their own expenses. The lawsuit against EOS
                  was officially withdrawn on October 6, 1997. The lawsuit
                  against Kostal was officially withdrawn on October 1, 1997.
                  Neither lawsuit may be reinstituted. Accordingly, the court
                  order which required 3D to post a performance bond in the
                  amount of 1.1 million Deutchmarks to cover certain potential
                  legal fees in the event of an unfavorable outcome to 3D was
                  also withdrawn and the restriction on cash eliminated.

         (d)      On January 13, 1997, 3D Systems, Inc. (the "Company") filed a
                  complaint ("Complaint") in the United States District Court,
                  Central District of California, against Aarotech Laboratories,
                  Inc. ("Aarotech"), Aaroflex, Inc. ("Aaroflex") and Albert C.
                  Young ("Young"). Aaroflex is the parent corporation of
                  Aarotech. Young is the Chairman of the Board and Chief
                  Executive Officer of both Aarotech and Aaroflex. The Complaint
                  alleges that stereolithography equipment manufactured by
                  Aaroflex infringes on six of the Company's patents. The
                  Company seeks damages and injunctive relief from the
                  defendants. The defendants have threatened to sue the Company
                  for trade libel. To date, the defendants have not filed such a
                  suit.

                  The defendants filed a motion to dismiss the complaint or
                  transfer the case to their home district in Virginia. The
                  District Courts' decision granting this motion has been
                  reversed as to defendant Aaroflex, and the case has been
                  remanded to the District Court for proceeding including
                  discovery and ultimately trial.

(e)               Centuri Corp., dba Estes Indus., Cox Acquisition Corp., dba
                  Cox v. 3D Systems Corp., Rogers Tool & Die, L.A.S.C. Case No.
                  BC 177962 (filed September 16, 1997) (FDH/RSC).

                  In January 1997, 3D Systems, Inc. entered into two contracts
                  with Centuri Corp., dba Estes Indus., Cox Acquisition Corp.,
                  dba Cox ("Cox") under which 3D was to create certain tooling
                  for Cox. Cox purported to terminate the contracts in or about
                  August 1997.

                  On September 16, 1997, Cox initiated a lawsuit against 3D for
                  Breach of Oral Contract, Fraud, Negligent Misrepresentation,
                  Conversion, Money Had and Received, and Accounting. The suit
                  also named Rogers Tool & Die, another contractor hired by Cox
                  to work with 3D in creating the tooling. Cox contended that it
                  was damaged by 3D's and Rogers' alleged inability to timely
                  complete the contracts. On October 31, 1997, 3D demurred to
                  Cox's Verified Complaint. Rogers joined in 3D's demurrer. 3D's
                  demurrer contended that written, not oral, contracts governed
                  the relationship of the parties, that the Complaint did not
                  adequately plead the required elements of fraud, that the
                  Complaint failed to state a claim for Negligent
                  Misrepresentation, Conversion, and Money Had and Received, and
                  that Accounting was not actually a cognizable cause of action,
                  but an equitable remedy.

                  After a hearing on December 2, 1997, the Court sustained 3D's
                  demurrer, ordering Cox to file an amended complaint. On
                  January 29, 1998, Cox filed a Verified Amended Complaint,
                  asserting causes of action for Breach of Written Contract,
                  Fraud, and Negligent Misrepresentation. The Verified Amended
                  Complaint also stated identical claims against Rogers. The
                  Company believes that the case has no merit and intends to
                  vigorously defend this action.

                  The Company is engaged in certain additional legal actions
                  arising in the ordinary course of business. On the advice of
                  legal counsel, the Company believes it has adequate legal
                  defenses and that the ultimate outcome of these actions will
                  not have a material adverse effect on the Company's
                  consolidated financial position, results of operations or cash
                  flows.

(19)     SUBSEQUENT EVENTS

         (a)      In the first quarter 1999, the Company sold the assets and
                  assigned the lease for it's 3D Keltool St. Paul, MN operations
                  to Rapid Tooling Technologies, a subsidiary of Rapid Design
                  Technologies ("RDT"). As part of this agreement, RDT was
                  issued a multi year license fee for the use of the 3D Keltool
                  process.

         (b)      The Company announced availability of a significant number of
                  new products in the first quarter including:

                  -  SLA 7000 - 400% faster, on average, than the next fastest
                     SLA Industrial System. The SLA 7000 has a dual spot laser
                     that reduces downtime and errors while producing parts at
                     .001 inch layers thickness in far less post processing
                     time.

                  -  ThermoJet Solid Object Printer - is the successor to the
                     Actua 2100, offering a significant improvement in speed,
                     up to 300% faster. In addition, the ThermoJet uses a new
                     material, with improved part capabilities and color
                     capability.

                  -  3D Lightyear - part preparation software that exploits the
                     power of the Windows NT operating system, delivering
                     functionality that extends beyond the capabilities of
                     Unix-based Maestro.

                           PATENT LICENSE AGREEMENT


     THIS PATENT LICENSE AGREEMENT ("Agreement") is made this ____day of 
_______________, 1998 (the "Effective Date") by and between 3D Systems, Inc.,
a corporation organized and existing under the laws of the State of 
California, U.S.A., and having an office at 26081 Avenue Hall, Valencia, 
California, U.S.A. ("3D") on the one hand, and NTT DATA CMET INC., a 
corporation organized and existing under the laws of Japan, and having an 
office at 15-8 Kamata 5-Chome, Oota-ku, Tokyo  144-0052, Japan ("CMET") and 
NTT DATA CORPORATION, a corporation organized and existing under the laws of 
Japan, and having an office at Toyosu Center Building, 3-3  Toyosu 3-Chome, 
Koto-ku, Tokyo 135-6033, Japan ("NTT DATA") on the other hand (3D and CMET 
and NTT DATA hereafter occasionally referred to as "party" or "parties").

     This Agreement is made with reference to the following:

     A.  The parties each own certain patent rights relating to 
Stereolithography.

     B.  The parties have jointly concluded that their respective needs and 
interests will be served by a mutual exchange of licenses of the patent 
rights.

     THEREFORE, 3D on the one hand, and CMET and NTT DATA on the other hand, 
agree as follows:

1    DEFINITIONS

     1.1  The terms "Agreement" and "Effective Date" shall have the meanings 
ascribed to them above. 

     1.2  "Affiliate" with respect to a party means any corporate or other 
legal entity in which a party directly or indirectly owns or controls at 
least eighty percent (80%) of participating shares entitled to vote for the 
election of directors, or eighty percent (80%) of the equity interest having 
the power to direct management policies. 

     1.3  "Cover" or "covered" with respect to an apparatus or method in 
question, shall mean that:  (i) the act of making, using, offering to sell or 
otherwise dispose of, selling or otherwise disposing of, or importing the 
apparatus or method, which act if done without authority of the patent owner, 
would infringe, either literally or under the doctrine of equivalents, at 
least one claim of an issued and unexpired Patent, under the laws of the 
country in which such act occurs; or (ii) the act of inducing infringement, 
either literally or under the doctrine of equivalents, if such act, which act 
if done without the authority of the patent owner, is contrary to the laws of 
the country in which an issued and enforceable Patent is in existence at the 
time and in the country that such act occurs.  However, any patent claims 
that have been invalidated by a competent authority 

                                       1
<PAGE>

in a decision from which an appeal has not been taken shall not cover an 
apparatus or method in question. 

     1.4  "Patents" shall mean all patents owned or controlled by the parties 
that contain a claim or claims applicable to Stereolithography. 

     1.5  "Licensed Patents" of a granting party shall mean and include all 
issued Patents and pending patent applications containing one or more 
published claim(s) applicable to Stereolithography having an effective filing 
date earlier than the Effective Date, including all issued Patents and 
pending patent applications containing one or more published claim(s) 
applicable to Stereolithography that were or will be filed subsequent to the 
Effective Date but are entitled to claim the benefit of the effective filing 
date prior to the Effective Date. 

     1.6  "Licensed Products" shall mean any and all Stereolithography 
equipment and software dedicated thereto of a party which are covered by one 
or more Licensed Patents of the other party.  

     1.7  [Confidential Treatment Requested].

     1.8  "Stereolithography" shall mean and include equipment, systems, 
supplies and software utilized in the fabrication of three-dimensional 
objects, layer-by-layer from photo-curable liquid materials. 

     1.9  [Confidential Treatment Requested]. 

     1.10 "3D Licensed Territory" shall mean all countries of the world. 

2     GRANT OF LICENSE; RELEASE
 
      2.1  3D hereby grants a personal, non-transferable, and non-exclusive 
right and license under 3D's Licensed Patents:  (i) to CMET and its 
Affiliates, to make, have made, use, sell, lease, or otherwise dispose of, 
and import Licensed Products and spare parts and replacement parts for the 
Licensed Product in the CMET/NTT DATA Licensed Territory; and (ii) to NTT 
DATA and its Affiliates, to make, have made, use, sell, lease or otherwise 
dispose of, and import Licensed Products and spare parts and replacement 
parts for the Licensed Product in the CMET/NTT DATA Licensed Territory. 

     2.2  The right and license granted to CMET, NTT DATA and their 
Affiliates in Section 2.1 shall not include the right, directly or 
indirectly, by implication, estoppel or otherwise, to sublicense another.  
The sale, lease or other disposition by CMET or NTT DATA of a Licensed 
Product in the CMET/NTT DATA Licensed Territory shall not convey, by 
implication, estoppel or otherwise, to the party to which the Licensed 
Product was sold, leased, or otherwise transferred, any license or right 
under the Licensed Patents, except that any such party (i) may use, sell, 
lease or otherwise dispose of the acquired Licensed 



                                       2
<PAGE>


Product in the CMET/NTT DATA Licensed Territory, (ii) may only export the 
acquired Licensed Product to a country outside of the CMET/NTT DATA Licensed 
Territory for use in a branch office of the same party or a subsidiary 
thereof for the personal business use of the party and/or subsidiary thereof, 
provided that such use shall not include the right to sell or otherwise 
provide to any third party any parts or models made on such acquired Licensed 
Product, and (iii) may use, sell, or otherwise dispose of products throughout 
the world that are produced or designed using the acquired Licensed Product. 

     2.3  CMET and NTT DATA hereby grant a personal, non-transferable, 
paid-up and non-exclusive right and license under both CMET's and NTT DATA's 
Licensed Patents to 3D and its Affiliates to make, have made, use, sell, 
lease, or otherwise dispose of, and import Licensed Products and spare parts 
and replacement parts for the Licensed Product throughout the world, 
provided, however, that the right and license with respect to any of the CMET 
and NTT DATA's Licensed Patents that are co-owned with a third party are 
contingent upon each third party's consent, which third parties are not 
controlled by CMET or NTT DATA.  CMET and NTT DATA shall make all reasonable 
efforts to timely obtain the consent of each such third party. 

     2.4  The right and license granted to 3D and its Affiliates in Section 
2.3 shall not include the right, directly or indirectly, by implication, 
estoppel or otherwise, to sublicense another.  The sale, lease or other 
disposition by 3D of a Licensed Product in the 3D Licensed Territory shall 
not convey, by implication, estoppel or otherwise, to the party to which the 
Licensed Product was sold, leased, or otherwise transferred, any license or 
right under the Licensed Patents, except that any such party may use, sell, 
lease or otherwise dispose of the acquired Licensed Product, and may use, 
sell, lease or otherwise dispose of products throughout the world that are 
produced on or designed by use of the acquired Licensed Product. 

     2.5  No right or license is granted herein, to CMET, NTT DATA, 3D, or 
any third party, by implication, estoppel or otherwise under any patent, 
patent application or other patent right other than the Licensed Patents. 

     2.6  No right or license is granted, by implication, estoppel or 
otherwise, other than those rights and licenses expressly granted in this 
Agreement. 

     2.7  3D hereby releases CMET and NTT DATA and CMET and NTT DATA both 
release 3D, and all purchasers and users of Licensed Products acquired, 
either directly or indirectly, from the released party from any and all 
claims, demands, and rights of action which the releasing party may have on 
account of any infringement of any Licensed Patent by the manufacture, use, 
sale or other disposition or importation of Licensed Products which, prior to 
the effective date of this Agreement, were manufactured, used, sold or 
otherwise disposed of or imported by the released party;

6    TERM AND TERMINATION

     6.1  This Agreement shall commence on the Effective Date and shall 
extend for the life of the last to expire of the Licensed Patents.

     6.1.1  [Confidential Treatment Requested]

     6.2  In addition to the right of termination provided in Article 5.1 by 
CMET and NTT DATA, either party shall have the right to terminate this 
Agreement, or the rights granted by it hereunder, as a result of the other 
party's material breach.  The party claiming breach of the Agreement shall 
give the other party written notice of the breach, specifying the nature 
thereof, and the other party shall have thirty (30) days after such notice to 
cure such breach.  Upon the failure of the party in breach to cure the breach 
within the thirty (30) day period, the other party shall have the right to 
terminate this Agreement by giving written notice of termination.  This 
Agreement shall terminate effective on the date set forth in the termination 
notice.  The right of a party to terminate this Agreement for material breach 
shall be in addition to and not in lieu of any other right or remedy that the 
terminating party may have at law or in equity, including without limitation, 
the right to sue a breaching party for any prior breach of the Agreement, or 
for breach of the whole Agreement or any unperformed balance thereof.  
Failure of a party to conform to the provision of Article 7.4 of this 
Agreement shall be deemed a material breach.

     6.3  Unless impermissible under the applicable laws as of the date that 
written notice of termination is given, either party shall have the right to 
terminate this Agreement, or the rights granted by it hereunder, by giving 
the other party written notice of a termination as a result of such other 
party being for more than sixty (60) days the subject of any voluntary or 
involuntary proceeding relating to bankruptcy, insolvency, liquidation, 
receivership, or assignment for the benefit of creditors.  This Agreement 
shall terminate effective on the date set forth in the termination notice.

     6.4  On the effective date of any termination, cancellation or 
expiration of this Agreement, the rights and licenses granted herein shall 
terminate.

     6.5  [Confidential Treatment Requested]


                                       5
<PAGE>

     6.6  Neither party shall be liable for damages of any kind as a result 
of properly exercising its respective right to terminate or cancel this 
Agreement, or rights granted hereunder, according to the terms and conditions 
of this Agreement, and termination or cancellation will not affect any other 
right or remedy of either party.

     6.7  Any confidentiality obligations imposed on the parties under this 
Agreement shall survive and remain binding on parties for a period of three 
years after the date of any termination, cancellation or expiration of this 
Agreement.

7    GENERAL PROVISIONS

     7.1  CONFIDENTIALITY OF AGREEMENT.  The parties agree that the terms of 
this Agreement are to be strictly confidential, and neither party shall 
disclose such terms to any third party except:  (i) to legal counsel; (ii) to 
auditors; (iii) to the extent, if any, required by law (e.g., a governmental 
filing); (iv) in accordance with the terms of a protective or other order 
duly entered in a legal proceeding; or (v) with the prior written consent of 
the other party.  If disclosure of this Agreement or the terms and conditions 
thereof is required to be made in a governmental filing (e.g., a filing with 
the Securities and Exchange Commission), the disclosing party shall request 
confidential treatment of the terms and conditions of this Agreement and use 
its best efforts to ensure that confidential treatment is so afforded to such 
terms and conditions, as may be permitted under the rules of the applicable 
governmental agency.  When 3D submits this License Agreement to the 
Securities and Exchange Commission ("S.E.C."), CMET and NTT DATA will be 
permitted to review 3D's request to maintain the confidentiality of the 
sections that CMET and NTT DATA deem to be confidential before the 
confidentiality request is filed with the S.E.C. and to submit a statement 
prepared by CMET and NTT DATA together with the confidentiality request, if 
CMET and NTT DATA deem such action to be appropriate.  Furthermore, 3D will 
timely advise CMET and NTT DATA of any objections by the S.E.C. to the 
confidentiality request and permit CMET and NTT DATA to be involved in any 
further proceedings that are initiated to maintain the confidentiality of the 
sections of the License Agreement that CMET and NTT DATA deem to be 
confidential.  If a party intends to publicly announce any information with 
regard to this Agreement, that party must obtain prior, written consent from 
the other parties to be permitted to make such public announcement.

     7.2  GOVERNING LAW AND DISPUTE RESOLUTION.  This Agreement shall be 
governed and interpreted in accordance with the substantive laws of Japan.  
The parties agree that any action to enforce this Agreement shall be filed 
in, and the parties consent to personal jurisdiction and venue in, the Tokyo 
District Court; provided that any disputes between the parties caused or 
arising out of the difference between the parties whether a product is 
covered by a claim or claims of any one of a Licensed Patents shall be 
submitted for arbitration to the Arbitration Center in Tokyo, Japan, which is 
co-managed by the Japan Federation of Attorneys Bar Association and the Japan 
Patent Attorneys Association.  The parties agree to submit such disputes to 
the exclusive 


                                       6
<PAGE>

jurisdiction of first instance to such Arbitration Center, and the finding(s) 
of the Arbitration may not be overruled unless clearly erroneous.
 
     7.3  NON-ASSIGNABILITY OF THIS AGREEMENT.  This Agreement and the rights 
and obligations of the parties hereunder may be assigned only to an Affiliate 
of either party or to a purchaser of the entire business or all the assets to 
which this Agreement pertains (regardless of the form of the sale of such 
businesses or assets) without the prior written approval of the other party 
hereto.  Any other assignment entered without prior, written approval shall 
be null and void. Notwithstanding the foregoing, with respect to any 
assignment by either party, the assignee shall not be released or otherwise 
relieved of any liability for infringements occurring prior to the date of 
the assignment.

     7.4  NON-ASSIGNABILITY OF LICENSED PATENTS.  Neither party may assign 
any patents or patent applications included with the Licensed Patents for 
which a registration or recordation of the terms of this Agreement has not 
been completed (irrespective of whether such assignment is voluntarily or 
otherwise) without giving notice of this Agreement to the intended assignee 
of the Licensed Patent(s) and obtaining from such intended assignee a written 
consent, which consent shall be addressed to the other party or parties, that 
the intended assignee shall not enforce the assigned Licensed Patent(s) 
against the relevant Licensee(s) nor make any claims or demands on the 
assigned Licensed Patent(s) against the relevant Licensee(s) and shall be 
bound by the same obligation of the grantor as herein provided.  Any 
assignment executed without obtaining such written consent shall be null and 
void.

     7.5   REGISTRATION OF LICENSE.  Each licensed party shall have the right 
to register or record its license with regard to any Licensed Patents in any 
and all appropriate government agencies and the granting party shall take all 
reasonable efforts to cooperate to effect such registration.  Upon issuance 
of any Japanese Licensed Patents, the parties shall perform all necessary 
procedures to register the non-exclusive license.  The Licensee of such 
Japanese Licensed Patents shall bear all of out-of-pocket expenses arising 
from such procedure.

     7.6  NOTICES.  All notices provided for in this Agreement shall be 
effective when received by personal delivery, telecopier or telex, or one 
business day after being received by courier or by registered or certified 
airmail at the following address:

or such other address as either party shall hereafter designate in writing to 
the other.

     7.7  INVALIDITY OF PROVISION.  If any of the provisions of this 
Agreement shall be held by a court or administrative agency of competent 
jurisdiction to contravene the laws of any country, it is agreed that such 
invalidity or illegality should not invalidate the whole Agreement, but this 
Agreement shall be construed as if it did not contain the provision or 
provisions held to be invalid or illegal in the particular jurisdiction 
concerned, and insofar as such construction does not affect the substance of 
this Agreement and the rights and obligations of the parties hereto, it shall 
be construed and enforced accordingly.  In the event, however, that such 
invalidity or illegality shall substantially alter the relationship between 
the parties hereto, affecting adversely the interest of either party, then 
the parties hereto shall negotiate a mutually acceptable alternative 
provision not conflicting with such laws.

     7.8  ENTIRE AGREEMENT, AMENDMENTS, WAIVERS.  This Agreement represents 
the entire understanding and agreement between the parties hereto with 
respect to the subject matter hereof, and supersedes all prior and 
contemporaneous negotiations, representations and agreements made by and 
between such parties.  The parties acknowledge that they have not relied upon 
any representation whatsoever of the other which is not contained in this 
Agreement.  There are no understandings, obligations, representations or 
warranties except as herein provided for and no rights are granted except as 
expressly set forth in this Agreement.  Any waiver by either party of the 
breach or default of any of the terms or conditions of this Agreement by the 
other party will not be considered as a continuing waiver or a waiver of any 
other prior, contemporaneous or subsequent breach or default, whether the 
same as or similar to or different from, the breach or default waived.  No 
alteration, amendment, variation, supplementation, modification or waiver of 
any of the terms or provisions of this Agreement shall be binding or 
effective for any purpose unless made pursuant to an instrument in writing 
signed by 3D and both CMET and NTT DATA.

     7.9  REPRESENTATIONS AND WARRANTIES.  Each of the parties represents and 
warrants that it has not accepted and will not accept any commitments or 
restrictions in respect to its right to grant licenses which will materially 
affect the value of the rights granted by it in this Agreement.

     7.10  Nothing in this Agreement shall be construed as:

     7.10.1  A warranty or representation by either party as to the validity 
or scope of any Licensed Patent; or

     7.10.2  A warranty or representation that anything made, used, sold or 
otherwise disposed of under any license granted in this Agreement is or will 
be free from infringement of patents of third persons; or

     7.10.3  A requirement that either party shall file any patent 
application, secure any patent, or maintain any patent in force; or

     7.10.4  [Confidential Treatment Requested]

     7.10.5  An obligation to furnish any manufacturing or technical
