3D Systems Releases Durable Material for Low-End Industrial System.

Business Editors

VALENCIA, Calif.--(BUSINESS WIRE)--Nov. 29, 2000

3D Systems Corp. (Nasdaq:TDSC) today announced the release of a new durable material -- SL 5240 -- for its SLA(R)250 system.

The polypropylene-like material will be available by the end of December.

SL 5240 material is the latest in a series of materials developed by 3D Systems and Vantico Inc. The new material follows the earlier release of SL 7540, which is the equivalent material for the SLA 3500, 5000 and 7000 solid imaging systems. Both materials offer mechanical properties similar to thermoplastic.

"SL 5240 material can produce parts that are durable enough for functional testing, in some cases eliminating the need for interim steps such as bridge tooling," said Suresh Jayanthi, director of applications development. "Yet, the material's durability does not come at the cost of accuracy. Both properties are achieved with the added benefits of fast build speeds and minimal post-processing."

Jayanthi said, "SL 5240 material is ideal for use in production components, which allows customers to delve into more customized, short-run manufacturing with the SLA 250 system."

"The material enables us to produce more functional parts from our SLA 250 system," said Stacie Van Dorin, manager of rapid prototype engineering at Solid Concepts Inc. "It takes us one step closer to functional prototyping."

"Custom manufacturing is driving the need for functional materials such as SL 5240," said Grant Flaharty, senior vice president of worldwide sales and marketing at 3D Systems. "Our growing base of durable materials is opening the door for manufacturers to create finished, customized parts straight from our solid imaging machines. As a result, our stereolithography technology is moving from basic rapid prototyping into custom manufacturing applications."
