3D SYSTEMS REPORTS SECOND QUARTER AND FIRST HALF RESULTS

VALENCIA, Calif.--(BUSINESS WIRE)--July 17, 2002--3D Systems Corp. (Nasdaq:TDSC
- - NEWS) today announced second quarter 2002 revenue of $28.8 million and a net
loss of $6.0 million or $0.46 per fully diluted share compared with year ago
revenue of $25.0 million and a net loss of $0.3 million or $0.03 per fully
diluted share for 3D Systems prior to the acquisition of DTM Corporation. The
loss in Q2 2002 includes $1.9 million in severance and other restructuring
costs, $1.0 million in legal costs relating to the now completed Department of
Justice and DTM acquisition matter and other legal matters, and $1.0 million in
resin conversion costs.

Revenue and net income for the first six months of 2002 totaled $56.0 million
and $2.5 million or $0.18 per fully diluted share compared with revenue of $52.9
million and net income of $1.0 million or $0.08 per fully diluted share recorded
by 3D Systems prior to the acquisition of DTM for the first half of 2001.
Included in the first half results is a $18.5 million pretax benefit associated
with the Vantico arbitration settlement.

Stated Brian K. Service, "Companies worldwide appear to remain hesitant to
commit to purchasing major capital equipment, especially for use in traditional
rapid prototyping applications. The situation appears to be somewhat better in
the newer application areas of Advanced Digital Manufacturing(SM) which
accounted for 35% of revenue in the quarter, and the interest level in
developing ADM applications is high. Recurring revenues increased to 57%
compared to 55% in the prior year period, despite reduced resin revenue at 53%
of prior year.

"Our resin materials conversion program has been proceeding well ahead of plan
with margins also remaining above expectation. Currently, we estimate we are the
Number 1 supplier worldwide on a volume basis. We expect to introduce a number
of new materials in 2002 and across all platforms," continued Service.

"The company's transition, since completing the acquisitions of DTM and RPC
Ltd., the Vantico separation and now the agreement with the Department of
Justice to license our stereolithography technology in the U.S., continues in a
very difficult business environment. Business appears to have stabilized,
although at a lower level than expected. Accordingly, we have decided to further
consolidate

                                       1


and streamline operations, both here and in Europe, in line with current revenue
expectations. The former DTM facility in Austin, Texas will be closed and
European operations will be reorganized. Research and development operations
will be focused at Grand Junction, Colorado and Valencia, California. We expect
to announce further measures to reduce costs in the next few days," Service
said.

"Overall, we believe we have a solid business and a good opportunity for
long-term growth in ADM, but we must conserve our resources and control our
costs to operate more efficiently and effectively until the business environment
improves," he added.

As previously announced, 3D Systems will hold a conference call today to discuss
the first half results at 9:30 a.m. Eastern Daylight Time (6:30 a.m. Pacific
Daylight Time). To access the call, dial 877/613-8341 or 706/679-7620

About 3D Systems

Founded in 1986, 3D Systems, the solid imaging company(SM), provides solid
imaging products and solutions that reduce the time and cost of designing
products and facilitate direct and indirect manufacturing. Its systems utilize
patented technologies to create physical objects from digital input that can be
used in design communication, prototyping, and as functional end-use parts.

3D Systems currently offers the ThermoJet(R) solid object printer, InVision(TM)
si2(TM) 3-D printer, SLA(R) (stereolithography) systems, SLS(R) (selective laser
sintering) systems, and Accura(TM) materials (including photopolymers, metals,
nylons, engineering plastics, and thermoplastics).

3D Systems is the originator of the ADM (Advanced Digital Manufacturing(SM))
solution for manufacturing applications. ADM is the utilization of 3D Systems
solid imaging technologies to accelerate production of smaller volumes of
customized/specialized parts. A typical ADM center is expected to contain
multiple 3D Systems' SLA, MJM and/or SLS systems dedicated to full-time
manufacturing applications.

Product pricing in the U.S. ranges from $49,995, for the ThermoJet printer, to
$799,000 for the high-end SLA 7000 system. 3D Systems' multiple platform product
line enables companies to choose the most appropriate systems for applications
ranging from the creation of design communication models to prototypes to
production parts. More information on the company is available at
