Open to students worldwide, this annual 3D printing challenge invites students in Engineering, Design and Art, or Architecture to create a new product that improves how a task is accomplished or to redesign an existing product. Entries should be mechanically sound, realistic and achievable, and are judged based on:
- Sound mechanical design and part integrity
- Compelling description (written and/or video)
- Design creativity
- Product usefulness
- Aesthetic appeal
Individual students or two-person teams are required to create designs using 3D CAD software and to submit their design files in .STL format to Stratasys, along with a written description and/or a 30-second video explaining the value and benefit of the Extreme Redesign model. The deadline to submit entries is Feb. 11, 2015. Categories for the 11th annual worldwide challenge include:
- Engineering: Secondary Education (middle and high school)
- Engineering: Post-Secondary (university, college or post-secondary)
- Art and architecture (any grade level)
Prizes Include 3D Printers, Trips and Scholarships
New this year, the first-place student winner in the Post-Secondary category will win a trip to a 3D printing/additive manufacturing conference in 2015 (location to be determined)! First-place winners in every category will receive $2,500 USD scholarships, and the instructors of the first-place students will receive a demo Stratasys 3D Printer for a limited time to use in the classroom. Second and third place winners will receive $1,000 USD scholarships. The Top 10 entries in each category will receive a Stratasys apparel item (value up to $50) and regional semi-finalists will receive a 3D printed model of their design. Each entrant will receive an official Extreme Redesign T-shirt.
Last Year’s Winner: Batman-like Car Chassis Featuring Organic Design
This past April, Stratasys announced the winners of its 10th Annual Challenge. Students from around the world were recognized for their accomplishments in reimagining the world around them. Wallace Penn Scott won first place in the Art & Architecture Category for his innovative approach to car chassis design.
Scott applied topology optimization to a supercar model that he helped design with his student team at Lehigh University. Topology optimization strips the dead weight off a load-bearing structure (in this case, the car’s chassis), providing efficient design solutions for designers, architects and engineers.
“The goal was to ask the computer to find the lightest, stiffest chassis possible for our custom design,” Scott explained. “When you let [topology optimization] work freely and not worry about manufacturing constraints, you get these beautiful, organic results.”
Scott likens the appearance of his car chassis to a spider’s web and believes that the highly organic results of topology optimization are a perfect match for 3D printing.
“Concept design has really been about making our best guess for what a solution might look like, and there’s no doubt we do a good job of it. But now we can find perfect, customized solutions for each of our unique applications— we’re moving past the world of ’one size fits all.’ ”
Scott’s chassis was enthusiastically received within the global optimization community and was selected for presentation at the inaugural OPTI-i Conference in Kos Island, Greece.
“People everywhere have this tangible excitement when it comes to optimization and additive manufacturing. Everyone knows that big things are coming, and we’re struggling to imagine what’s going to take shape.”
Indeed, topology optimization and 3D printing show promise far beyond cars and consumer products. Scott wonders what radical, organic redesigns await concert halls, skyscrapers and solar panel trees. “My dream of the futures is one that doesn’t just exceed our expectations,” said Scott, “but also thrills us when we arrive.”
