If you're one of those people who is certain they can build a better mousetrap or reinvent the wheel, Stratasys is now accepting submissions to the 11th annual Extreme Redesign 3D Printing Challenge.

It's open worldwide, and the annual 3D printing challenge calls on students in engineering, design, art or architecture to either create a new product which improves how a task is accomplished or to redesign an existing product.

According to the rules of the challenge, entries must be mechanically sound, realistic and achievable to take home the prize. The submissions will be judged on whether they demonstrate sound mechanical design and part integrity, if they include a compelling description, exhibit design creativity and can show product usefulness.

Entrants will, either as individual students or two-person teams, be required to create designs using 3D CAD software and to submit those design files in .STL format to Stratasys online. Each entry must include a written description and or a 30-second video explaining the value and benefit of the model.

The deadline to submit entries is Feb. 11, 2015, and the categories in the competition will include; engineering: Middle and High school, engineering: Post-Secondary (university, college or post-secondary) and Art or architecture entries at any grade level.

This year, the first-place student entry in the post-secondary category takes down a trip to a 3D printing or additive manufacturing conference in 2015, while first-place winners in every category will receive $2,500 scholarships. The instructor of the first-place student will also receive a demo 3D printer for a limited time to use in their classroom.

Second and third place winners will receive $1,000 scholarships and the top-10 entries in each category will receive a Stratasys apparel item. Regional semi-finalists will receive a 3D printed model of their design and each person who enters will receive an official Extreme Redesign T-shirt.
