This Post-Effective Amendment No. 1 to the Registration Statement shall become
effective immediately upon filing with the Securities and Exchange Commission in
accordance with Section 8(a) of the Securities Act of 1933, as amended, and Rule
462 thereunder.
REALLOCATION
On May 13, 1997, DTM Corporation (the "Registrant") registered on Form
S-8 Registration Statement Number 333-26985, 357,755 shares of Common Stock for
issuance under the DTM Corporation Stock Option Plan which was implemented in
1996 (the "1996 Plan"). In May 1999, such shares of Common Stock were
incorporated into the DTM Corporation 1999 Stock Incentive Plan (the "1999
Plan"), which is the successor to the 1996 Plan. Therefore, the Registrant is
hereby reallocating to the 1999 Plan the 357,755 shares previously registered
under the 1996 Plan, with such reallocation to be effective immediately upon the
filing of this Post-Effective Amendment. The Registrant will reregister such
shares under the 1999 Plan on a new Form S-8 Registration Statement. No further
option grants or stock awards will be made under the 1996 Plan.
