VALENCIA, Calif.--(BUSINESS WIRE)--Sept. 5, 2002

3D Systems Corp. (Nasdaq:TDSC) today announced the purchase of an initial two Vanguard(TM) SLS(R) (selective laser sintering) si2(TM) systems, by On Demand Manufacturing (ODM), a new subsidiary of The Boeing Company (NYSE:BA) in Camarillo, Calif.

As part of 3D Systems' Advanced Digital Manufacturing(SM) (ADM) solution, the newly acquired SLS systems will be used by ODM to perform rapid, low cost fabrication of small lots of complex, hard-to-manufacture parts. Because the SLS systems require no tooling or molding equipment, they will provide a significant reduction in the time and cost of manufacturing these parts.

ODM's first contract will be to supply parts to Boeing for the environmental control system ducts of military aircraft. "We are starting off with non-structural parts, but we have a vision to take it much further. We are ramping up quickly and, if all goes as planned, we expect to have several more Vanguard sinterstations by this time next year," said John Wooten, general manager for ODM.

"At the core of ODM's Advanced Digital Manufacturing approach is 3D Systems' laser sintering technology," explained Scot Thompson, Global Business Director, Aerospace for 3D Systems. "3D Systems' recent advances in software, materials, and process have advanced this technology from what was once primarily used to develop prototype parts to the creation of actual end-use parts through ADM.

"ODM understands the benefits of this ADM technology. Design engineers are now totally free to design purely for functional use, rather than being limited to conventional design due to manufacturing constraints. By utilizing our SLS systems, ODM is capable of building components on demand directly from digital data.

"We are delighted to work with ODM and Boeing to further develop ADM solutions for aerospace," continued Thompson. "Boeing is truly a pioneer in this revolutionary manufacturing process and is already using the SLS system for parts production for other military aerospace applications. Their vision and knowledge of specific requirements have led to extraordinary success in tool-less manufacturing. This is a perfect application to replace traditional tooling, producing end-use parts today and full life-cycle support into the future. We expect ODM and Boeing to lead the industry with their `build on demand' strategy," Thompson said.

About 3D Systems

Founded in 1986, 3D Systems, the solid imaging company(SM), provides solid imaging products and solutions to 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 used for design communication, prototyping and functional end-use parts.

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

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 www.3dsystems.com, or by phoning 888/337-9786, extension 811, or 661/295-5600 internationally. An investor packet can be obtained by calling 800/757-1799.

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 SLS systems dedicated to full time manufacturing applications.

About ODM

On Demand Manufacturing (ODM) has been operating as a Boeing subsidiary since June 6, 2002. The business originated from Boeing's Chairman's Innovation Initiative, which gives employees the opportunity to propose and develop new business concepts based on core technology or business strengths of the company -- in this case, laser sintering technology. Employees whose concepts are spun off into new ventures are given an opportunity to take a leadership role in these ventures.
