Under an engineering development agreement, 3D Systems is co-developing a proprietary Rapid Manufacturing methodology for the production of accurate, durable models of individual teeth and arches with crisp resolution that combines the 3M ESPE Chairside Oral Scanning technology with the Viper(TM) Pro SLA(R) System and a new proprietary Accura(R) SL Material.

Selected by 3M for its accuracy, repeatability, detail and production capacity, the manufacturing capable Viper(TM) Pro SLA(R) System converts proprietary materials and composites into solid cross-sections, layer by layer, until three-dimensional models are built. Additionally, 3D Systems and 3M ESPE developed a proprietary new material specifically for this high-volume, high-resolution application. The new Accura(R) Material exhibits high detail, higher durability and offers superior resolution and precision.

3M ESPE will introduce the Lava(TM) C.O.S. to dentists in North America and Europe in 2008. The Lava(TM) C.O.S. will provide an alternative to the traditional dental impression process and enable the high-speed 3-D motion capture of tooth anatomy used to create PFM and all-ceramic crowns and bridges manufactured by dental labs.

"This agreement has made 3D Systems the Rapid Manufacturing provider of choice for digital dentistry," said Abe Reichental, 3D Systems' president and chief executive officer. "Just as we have pioneered Rapid Manufacturing for the hearing-aid industry, we are pushing the envelope within the dental arena with our technology. We are thrilled to work with 3M ESPE on this useful solution that benefits both dental professionals and patients."
