MINNEAPOLIS — August 30, 2005 — The Dimension 3D Printing Group, a business unit of Stratasys, Inc. (Nasdaq: SSYS), announced today teacher incentives for encouraging students to participate in its second annual "Extreme Redesign: The Ultimate 3D Printing Challenge," a global design and 3D printing contest for high school and college students that awards scholarships to student winners.

Following on the success of Dimension's first annual Extreme Redesign awards program, the company will award teachers of first place student winners in this year's contest a Dell notebook computer for use in the classroom. In addition, the teacher with the most student entries overall will also receive a Dell notebook computer for encouraging student participation in the contest. To qualify, the instructor's name and email address should be included on the contest application form, available at www.dimensionprinting.com/extreme.html.

"We are pleased to offer teachers a useful incentive to encourage student participation in this year's 'Extreme Redesign' contest," said Jon Cobb, vice president and general manager of 3D printing for Stratasys. "The program gives students who have ever had a unique idea for extending the capabilities or enhancing the aesthetics of a part, product or piece of art a venue to share their idea with the world. With the introduction of a teacher incentive, we anticipate this year's contest to be even more popular as students around the world become inspired and challenged not only by this contest, but also with the possibilities of a career in design engineering."

Contest Details
Whether it's a new perspective on an everyday product or a fresh vision for updating a famous piece of art, animation or architecture, Dimension is once again calling on computer-aided-design (CAD) students worldwide to send in their most creative, useful and innovative Extreme Redesigns.

To enter, students send a .stl file of their Extreme Redesign to Dimension along with a completed submission form, including a 200-word description of the value and benefit of the Extreme Redesign part. Dimension will then send entrants a 3D print of their redesign they can hold in their hands and evaluate. From there, entrants have the opportunity to make any necessary design improvements and develop a second iteration for final submission.

Final submissions must be postmarked by Dec. 31, 2005. A panel of independent judges from various industries will judge final entries on the basis of creativity, usefulness, part integrity and aesthetics. Winners will be selected in February 2006 and will receive $2,500 or $1,000 scholarships. First place winners will travel to an awards ceremony at the National Design Engineering Show in Chicago in March 2006. Complete contest rules and submission information is available at www.dimensionprinting.com/extreme.html.

Design concepts from last year's high school and college winners included a lighted retractable leash, mouse radio and stair climbing robot. For photos and descriptions of last year's winning Extreme Redesigns, visit www.dimensionprinting.com/extreme_win.html.
