VALENCIA, Calif.--(BUSINESS WIRE)--March 3, 2003

3D Systems Corp. (Nasdaq:TDSC) has announced 3D Systems, Inc. have filed an action in the United States District Court, Western District of Texas against EOS GmbH Electro Optical Systems (EOS) of Krailling/Munich, Germany to stop the sales of EOS' laser sintering systems in the U.S. These systems are based on inventions that were developed, patented, and exclusively licensed by the University of Texas at Austin to 3D Systems. Consequently, The University has joined its licensee, 3D Systems, in seeking Injunctive Relief.

EOS recently announced the installation of an EOSINT P700 system in the U.S. It is the belief of 3D Systems and The University that EOS has ignored the licensed patents and diminished the value of the license by the importation and sale of the EOS P700 system. 3D Systems acquired the rights to the patents in 2001 through the acquisition of DTM Corporation, to whom the patents were exclusively licensed. EOS is not licensed under these patents and therefore it is 3D Systems' position that EOS does not have the right to be selling in the US.

"As EOS continues to sell its systems in the U.S., it is infringing upon 3D Systems' patent rights. Should the current suit be decided in 3D Systems' favor, it is our intent to notify U.S. purchasers of EOS' systems of their infringement and liability and to request that the customers propose a specific remedy for relief to 3D Systems," said Brian K. Service, 3D Systems Chief Executive Officer. "We understand that vendor choice is an essential part of proliferating and accentuating technology and we support this concept. However at the same time 3D Systems has a responsibility to its shareholders and to the UT to ensure they receive adequate recompense for the many years, and considerable investment, involved in creating this intellectual property," concluded Service.

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, 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.
