3D printing leader Stratasys has announced the winners in its 11th annual Extreme Redesign contest. As we reported last fall, the 2015 Extreme Redesign 3D Printing Challenge is open to middle school, high school, and college students around the world in engineering, design, and art or architecture.
Each year, students are invited to redesign an existing product, or come up with a design for a new product that improves how a task is currently done. Entries must be realistically achievable and mechanically sound, and are also evaluated on creativity. Students submit designs in three different categories: Secondary Education Engineering, which are middle and high school students; Post-Secondary Engineering, which are university, college, or post-secondary students; and Art & Architecture, open to students at any grade level.

Designs are judged on four different aspects: sound mechanical design and part integrity; design creativity; product usefulness; and a compelling written and/or video description. Designs submitted for the Art or Architecture category are also judged on aesthetics.

First-place winners in all categories receive a $2,500 scholarship, and the first-place student's instructor receives a demo 3D printer to use in the classroom for a limited time. For the first time, this year's first-place student winner in the Post-Secondary Engineering category also wins a trip to a 2015 3D printing/additive manufacturing conference. Second- and third-place winners receive $1,000 scholarships. You can see all of this years' winners, as well as past winners, here.

The first-place winner in the Extreme Redesign contest's Post-Secondary Engineering category is Cooling with Heat submitted by Melanie Gralow and Lena Heemann of the University of Bremen in Bremen, Germany. The prototype demonstrates an alternative solution to current PC cooling units. It harvests waste heat from the processor, about 40W to 80W, converts it into electricity and makes it available for uses such as powering the PC's cooling fan. Gralow and Heemann designed the unit's 3D-printed curved heat pipes and a 3D-printed biologically inspired heat spreading structure.
