3D Systems to Introduce New Multi-Jet Modeling Printer at SIGGRAPH.

Business Editors/High-Tech Writers

SIGGRAPH 2002

3D Systems Corp. (Nasdaq:TDSC) today announced that it will introduce the InVision(TM) si2(TM) 3-D printer at SIGGRAPH 2002. SIGGRAPH is an annual international conference and exhibition for the computer graphics community, where the "digital future is defined and revealed." On display will be a range of 3D Systems' products -- including the new InVision si2 3-D printer, a multi-jet modeling system which combines photocurable hot melt material with the ease of ink-jet printing.

"The InVision 3-D printer is intended to enable designers, engineers and other 3-D data users to quickly, easily and conveniently produce cost-effective, high-quality durable models and prototypes," said Mervyn Rudgley, Senior Director of Product Management. "There are more than one million mechanical CAD seats today and the market is growing 15% a year. This new solid imaging tool will enable designers to concentrate on the creative process while producing models in house."

Visit 3D Systems at SIGGRAPH 2002, July 23-25, in San Antonio, Texas, booth 5054. For more information regarding SIGGRAPH visit the 3D Systems web site at www.3dsystems.com.

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.
