May 16. 2008 - Minneapolis, MN - The Dimension 3D Printing Group, a business unit of Stratasys, Inc. (Nasdaq: SSYS), today announced a new trade-in offer that extends a $10,000 credit to commercial customers towards the purchase of a Dimension(R) SST 1200es 3D printer. The trade-in offer is available worldwide and will run through the summer of 2008.

The offer is good on the trade-in of 3D printing or rapid prototyping machines. For complete trade-in details contact a Dimension reseller, or to locate a reseller visit www.dimensionprinting.com or call toll free 888-480-3548 (U.S.). The SST 1200es, introduced in February of this year, features a 10 x 10 x 12-inch build size and offers engineers and designers the ability to print models with ABSplus. This build material is on average 40 percent stronger than standard ABS plastic, providing stronger functional models and improved surface finish.

"This credit makes it more affordable for customers looking to significantly upgrade their 3D printing capabilities," said Jon Cobb, vice president and general manager of 3D printing for Stratasys. "The SST 1200es moves closer to achieving the characteristics of injection molded models and combines increased model durability with the largest build size in the 3D printing space."

About The Dimension 3D Printing Group
The Dimension 3D Printing Group is a business unit of Stratasys, Inc., based in Minneapolis, Minn. Dimension 3D printers - which include the Elite, the Dimension 1200es Series and Dimension 768 Series - are networked, desktop modeling systems that provide CAD (Computer-Aided-Design) users a fast, office-friendly, low-cost alternative for building functional 3D prints. Dimension 3D printers build accurate models layer by layer using durable ABS plastic, allowing users to not only evaluate design concepts, but test 3D prints for functionality, form and fit. As the first large format desktop 3D printer that sells for less than $30,000, Dimension incorporates many key features found in modeling systems that cost tens of thousands of dollars more.

Stratasys Inc., Minneapolis, manufactures office-based rapid prototyping and direct digital manufacturing systems, 3D printers and offers rapid prototyping and manufacturing parts services. According to Wohlers Report 2008, Stratasys supplied 44 percent of all systems installed worldwide in 2007, making it the unit market leader, for the sixth consecutive year.
