      3D SYSTEMS ANNOUNCES RULING IN EOS VS. DTM/3D SYSTEMS PATENT LAWSUIT

VALENCIA, Calif. - Aug. 21, 2003 - 3D Systems Corp. (NASDAQ: TDSC) announced
today that the United States District Court for the Central District of
California issued claim construction and summary judgment rulings August 20,
2003, in the EOS GmbH Electro Optical Systems (EOS) vs. DTM Corporation (DTM)
and Compression, a division of Moll Industries, Inc. and 3D Systems, Inc. patent
infringement lawsuit. 3D Systems acquired DTM in August 2001.

As a result of a 1997 license agreement, EOS was licensed under the 3D Systems'
patents to the extent the patents pertain to the field of laser sintering. The
Court ruled that one claim of one of the 13 asserted 3D Systems' patents, US
Patent No. 5,630,981 (`981 patent), licensed to EOS was infringed by the DTM
machines at issue. The Court also ruled with respect to a patent issued to DTM,
US Patent No. 5,990,268 (`268 patent) that a key term was not able to be
construed. The `268 patent covers the use of nylon powders in laser sintering.
In addition, the Court ruled that EOS' assertion of infringement against DTM,
under the licensed 3D Systems' patents, was not barred by laches and estoppel.

Three other summary judgment motions on behalf of 3D Systems and DTM were
denied. The motions dealt with willful infringement of the powder `268 patent,
validity of the `268 patent, and license agreement interpretation with respect
to EOS being licensed under the DTM patents acquired by 3D Systems in the merger
with DTM. In other rulings, the Court construed three patent claim terms in a
manner that excludes as being applicable to laser sintering 11 of the 37 claims
EOS has asserted from the 3D Systems' patents as practiced by DTM.

"3D Systems is disappointed with the rulings but views this as one step in a
long process," said G. Walter Loewenbaum II, Chairman of the Board of Directors.
"3D Systems will appeal the rulings and believes that the law and the facts
favor its position




and will ultimately prevail, particularly given that these issues will be
reviewed anew in the appellate court."

ABOUT 3D SYSTEMS

Founded in 1986, 3D Systems(R), 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, SLA(R)
(stereolithography) systems, SLS(R) (selective laser sintering) systems, and
Accura(R) materials (including photopolymers, metals, nylons, engineering
plastics, and thermoplastics).

3D Systems is the originator of the advanced digital manufacturing (ADM(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.
