(EMAILWIRE.COM, September 05, 2002 ) 3D Systems Corp. (Nasdaq: TDSC) has announced the purchase of an initial two VanguardTM SLS® (selective laser sintering) si2TM 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 ManufacturingSM (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.
