Rock Hill, South Carolina, Dec. 5, 2007 - 3D Systems Corporation (NASDAQ: TDSC), a leading provider of 3-D Modeling, Rapid Prototyping and Manufacturing solutions, unveiled today Accura® Greystone Material, a new engineered nanocomposite material for its Stereolithography (SLA®) Systems.

Designed for motorsport and aerospace applications, Accura® Greystone Material delivers exceptional accuracy, stiffness, thermal performance as well as long-term stability. The grey-colored nanocomposite material was developed for rigorous, high pressure wind-tunnel testing, under-the-hood automotive applications and other uses requiring high thermal resistance, insulating electrical components, and building accurate and stable jigs and fixtures. Accura® Greystone material resists high temperatures and is intended for tooling and other demanding applications.

Stereolithography users, especially racecar and aerospace development teams, will find easy-to-use, easy-to-clean Accura® Greystone Plastic to be a best-in-class material for their development, testing and preproduction applications.

“Accura® Greystone Material is our latest breakthrough in material science and technology as we continue to emphasize the importance of engineered materials and composites to our business,” said Abe Reichental, 3D Systems’ president and chief executive officer. “We believe that it takes breakthrough materials like Accura® Greystone to push and expand the end-use applications’ envelope and broaden the adoption of additive manufacturing technology into the mainstream of automotive and aerospace design, development and manufacturing. As a leader and innovator in this exciting space, we are intensifying our commitment to material science research and expect to introduce additional high functionality breakthrough materials in the near future.”
