3D Systems Announces Significant Functionality Enhancements To Its Family of 3-D Printers Contact: Elizabeth Goode, Director, Corporate Development (661) 295-5600, ext. 2632 goodee@3dsystems.com Download PDF VALENCIA, Calif., Dec. 16, 2004 - 3D Systems Corporation (Nasdaq: TDSC), a leading provider of rapid 3-D printing, prototyping and manufacturing solutions, today announced the release of advanced user controls, added functionality and key feature enhancements designed to meet the requirements of its growing base of 3-D printing customers. Responding to lead customer requests, 3D Systems has enhanced its InVision™ HR 3-D printer with the capability of accepting .SLC file format. In addition, the Company offers a broader CAD compatibility, enabling customers to integrate third-party software with its standard InVision 3-D printer. “Major enhancements have been made to our InVision 3-D printer family to provide greater functionality to our customers,” said Abe Reichental, 3D Systems president and chief executive officer. “Our InVision HR 3-D printer was commercialized in July 2004 with high-resolution capability that enables jewelry, dental, medical implant and precision alloy manufacturers to produce fine-feature, highly detailed parts in a day, reliably and at an affordable price. The most widely used 3-D CAD format in the jewelry industry is the .SLC file format. Because .SLC file format is used to transfer highly detailed geometry in a more compact data form than .STL, .SLC file format capability represents a significant benefit to our jewelry users. Support of .SLC illustrates our continued commitment to offer additional CAD flexibility to our user family. “To achieve the convenience of a 2-D wide format printer or plotter, the InVision 3-D printer features two additional enhancements,” continued Reichental. “With this new functionality upgrade, we have created the foundation to embed seamlessly a ‘Print Preview’ tool for the InVision 3-D printer into any CAD system or other complementary software. This allows our customers to submit jobs to the InVision 3-D printer directly from their CAD package of choice. “In addition to the ‘Print Preview’, we have added ‘self-correcting intelligence’ functionality to the printer enabling fast real-time diagnostics and automated recovery in the event of simple operator or system related interruptions. “We believe that the significant functionality and key feature enhancements to our two affordable 3-D printers, and our recent commercialization of two new manufacturing-capable systems, positions us well to benefit from a growing market opportunity fueled by a population of nearly 500,000 qualified 3-D CAD users,” concluded Reichental.
