3D Systems Introduces New Hearing Aid Shells Manufacturing System with Dual-Vat -- the Viper HA SLA system.

VALENCIA, Calif. -- New Viper(TM) HA SLA(R) Will Be Displayed at the 49th International Congress of Hearing Aid Acousticians

3D Systems Corporation (Nasdaq:TDSC) announced today that it has introduced a new stereolithography (SLA(R)) system for manufacturing -- the Viper(TM) HA SLA system. The Viper HA SLA system is the second manufacturing system to be introduced by the company within three months. Developed by working closely with leading hearing aid manufacturers and suppliers, the comprehensive platform addresses manufacturing requirements from product planning to end-use production of hearing aid shells.

The new dual-vat hearing aid shells manufacturing system offers a variety of customer-enhanced innovations, including fast and convenient vat change over, integrated hearing aid software and process improvements that provide superior part quality and exceptional throughput.

The unique dual-vat design allows customers to produce two different color hearing aid shells simultaneously to accelerate production. By consolidating builds and eliminating batching delays customers experience faster part production and scheduling flexibility with shorter production batch cycles. The increased throughput and manufacturing flexibility results in optimized production of hearing aid shells and lower cost per part. Fast and easy vat change over is achieved through quick-release elevator arms which eliminate the need to clean system components between vat changes. The new material handling cart allows a single person to hoist, drain and filter vats, and to transfer and change vats in minutes.

The Viper HA SLA system is optimized for use with Dreve Fototec(R) SL materials and is tightly integrated with 3Shape A/S hearing aid manufacturing software to automate the data flow process. Integrated into the "Print Manager" of 3Shape, the software simplifies part preparation and build setup, resulting in reduced operator labor and cost.

"In addition to the Viper HA SLA system being the first stereolithography manufacturing system, it is also the first dual-vat system, allowing customers to build with two different materials at the same time," said Abe Reichental, 3D Systems' president and chief executive officer. "Working closely with industry leaders in the field of hearing aid materials and software, resulted in a first-ever integrated turnkey manufacturing system for direct manufacturing of hearing aid shells. The performance, speed and shell quality of the Viper HA SLA system was optimized using the Dreve Fototec SL materials. With the added functionality of the Viper HA SLA system, customers are able to produce in multiple colors, and increase their productivity by building a full set of hearing aid shells in one build, instead of two. Not only is this ideal for large production facilities but also those manufacturers producing smaller production lots.

"The Viper HA SLA system represents our continued commitment to pursuing direct manufacturing solutions," continued Reichental. "Harnessing leading planning and scheduling software from another recognized leader, 3Shape, provides our customers with an integrated manufacturing solution that simplifies their process and increases their productivity, and is yet another step towards improving our customer's bottom line," concluded Reichental.

3D Systems will display the Viper HA SLA system with Dreve at the 49th International Congress of Hearing Aid Acousticians, Messe Frankfurt, Hall 5.1, in the Dreve Stand A30. The show will take place in Frankfurt, Germany, on Wednesday, October 20, through Friday, October 22, 2004.

3D Systems plans to begin shipments of its new Viper HA SLA system in December of this year.
