VALENCIA, Calif.--(BUSINESS WIRE)--Dec. 19, 2002

3D Systems Corp. (Nasdaq:TDSC) today announced the availability of LaserForm(TM) ST-200 material for the SLS(R) systems. LaserForm ST-200 material is the next generation metals material that enables customers to produce complex parts and tooling inserts in a matter of days.

LaserForm ST-200 material allows customers to go beyond prototype tooling, enabling the production of tens of thousands of parts, even with aggressive injection molding materials. The material is comprised of 420 stainless steel, which is sintered in the SLS system. The sintered part is then infiltrated with bronze in an oven to produce a fully dense part or tool.

"LaserForm ST-200 material has characteristics similar to P20 steel. This allows customers with tooling applications, such as those in the automotive and aerospace industries, to use it to produce sintered parts and tools that are fully dense, with complex geometries and intricate feature detail, without the thermal stress associated with other technologies," said Mervyn Rudgley, Sr. Director Product Management. "As industries move toward Advanced Digital Manufacturing(SM) (ADM), our development of new materials is designed to provide designers and engineers with the ability to add custom features and complexity to their part designs. For the first time, engineers will be able to design without the necessity to adapt their designs to the limitations of traditional manufacturing methods," continued Rudgley. "The new binder system in LaserForm ST-200 material allows customers to produce parts and inserts with thinner walls and more complex features that were not possible with LaserForm ST-100 material.

"LaserForm ST-200 material has been well received by customers. North American and European customers have found the new material a significant step forward in the development of metal parts and inserts. In a recent customer trial, injection molding inserts, slides and rails composed of LaserForm ST-200 material were used to produce 40,000 pieces composed of a 30% glass-filled nylon 6.12, and tooling components showed no significant wear. Advantages for tooling applications include the ability to build in complex geometry without the expense of EDM tooling," concluded Rudgley.
