3D Systems Introduces a Precision, Durable Stereolithography Material with Molded ABS Plastic-Like Characteristics

VALENCIA, Calif.--Sept. 28, 2004--3D Systems Corp. announced today the immediate availability of its new Accura(R) si 50 SL material. Processing the new Accura(R) si 50 material through one of 3D Systems' designated SLA machines results in the production of parts with a higher degree of durability and accuracy, a combination of attributes not typically available in any other SL materials.

The look and feel of parts produced from the si 50 material resemble molded ABS thermoplastic parts, a highly desired characteristic enabling designers and engineers to closely simulate end-use parts. In addition, parts produced from si 50 material exhibit smooth, shiny sidewalls and excellent surface finish rendering the new si 50 material ideal for master pattern applications. The unique feature set combination of the si 50 material significantly expands the range of possibilities for customers seeking to reduce their time to market. It provides designers, engineers and marketers with the ability to produce models that closely match molded ABS parts resulting in shorter product design and testing cycle, saving valuable time and money. The Accura si 50 material is available in the two most common end-use part colors: ABS natural and grey.

This new material was designed, developed and optimized for use on the SLA(R) 7000, 5000, 3500 systems, and the Viper(TM) SLA system.

"This is a significant leap forward in the development of stereolithography materials," said Abe Reichental, 3D Systems' president and chief executive officer. "Prior to the development of this material, users had to choose between accuracy and durability, with si 50 material, they get both attributes in a single material. Lead-users who participated in the advanced testing of this product found it to be a best in class, versatile, multi-purpose material.

"As we continue to work with our customers and push our technology forward, we are able to develop materials that emulate end-use parts and meet or exceed our customers' requirements," continued Reichental. "Following on the heels of the Bluestone(TM) SL engineered nano-composite material, Accura si 50 material is the second material we have commercialized this quarter demonstrating our continued dedication to expand the material options available to our customers. By working closely with our customers we are developing materials with greater functionality, enhanced performance characteristics and versatility designed to improve our customers' bottom line."
