3D Systems Announces Fourth Quarter and 2001 Results



     VALENCIA, Calif., Feb. 20, 2002 - 3D Systems Corp. (Nasdaq: TDSC) today
announced fourth quarter 2001 revenue of $36.7 million compared with $31.7
million in the fourth quarter of 2000, an increase of 16%. Total revenue for
2001 was $121.2 million compared with 2000 revenue of $109.7 million, an
increase of 11%.

     Net loss for the fourth quarter of 2001 was $2.6 million or 20 cents per
diluted share compared with net income of $2.4 million or 18 cents per diluted
share in the fourth quarter of 2000. Net loss for 2001 was $1.3 million or 11
cents per diluted share compared with net income of $8.1 million or 63 cents per
diluted share in 2000.

     "The fourth quarter and 2001 revenue represents a record for the company
and is directly attributable to incorporating the results of the SLS(R) product
line acquired in August 2001 through the acquisition of DTM Corp.," said Brian
K. Service, president and CEO. "Comparing our fourth quarter results for 2001
with the results of the combined companies' for the fourth quarter of 2000 shows
a reduction in revenue of 16%. Using a similar comparison, the fourth quarter
gross profit margin was 43% compared with 49% in the fourth quarter of 2000.

     "While total fourth quarter SLA(R) and SLS unit sales were consistent with
the prior-year levels, the decrease in revenue and gross margins from operations
primarily is a result of fewer unit sales of high-end SLA systems. Decreased
resin revenues also contributed to the lower revenue and gross margins," Service
said.





     Total operating expenses for the fourth quarter of 2001 were $18.8 million,
including approximately $2 million of non-recurring costs associated with the
completion of the integration of DTM, $1 million for additional accounts
receivable reserves, and approximately $700,000 in legal fees resulting from the
Vantico arbitration.

     "During the fourth quarter of 2001, the integration of DTM's operations
substantially was completed, with the assembly operations, finance and
administration, and sales and service organizations being combined into 3D
Systems' existing business," Service added. "We are pleased with the
contribution that the SLS line of business has made to 3D Systems' overall
business since the acquisition. This product line and its potential
applications, especially relating to advanced digital manufacturing, is expected
to provide significant ongoing opportunities for the company in 2002 and
beyond."

     "We made significant improvements in our working capital position during
the quarter, reducing inventory by more than $5 million and accounts receivable
by $3.5 million," said E. James Selzer, senior vice president and CFO. "This
allowed us to reduce by $4 million the total debt incurred to fund the
acquisition of DTM. Improving our working capital position and reducing our debt
level continues to be a primary focus in 2002."

     "During 2001 significant acquisitions of new technologies and capabilities
were integrated into the company. In addition, the general economic conditions
in the second half of the year, the effects of the events surrounding September
11, the Department of Justice antitrust action, and the Vantico contract
termination provided additional challenges for the company," Service said.

     "Moving into 2002, we expect that the resolution of the divestiture
required by the Department of Justice, the conclusion of the Vantico
arbitration, and the transition to our own stereolithography resin supply,
coupled with the completion of the integration of our acquisitions, will be
reflected in the company's results," Service concluded.

     As previously announced, 3D Systems will hold a conference call today at
9:30 a.m. Eastern time to discuss the results. The call can be accessed by
dialing 877/613-8341 or 706/679-7620 internationally. A recording of the call
