Curious about three-dimensional printing? 3D printing has been an exciting development for many reasons, but here’s a very functional way to put a 3D printer to use: medical aids and orthotics. The VA has begun to use the technology to design braces, splits, and assistive devices. Printed titanium joints may be soon to come. An industrial designer named Or Steiner has already drawn attention for creating lightweight KAFOs with a Stratasys 3D printing system - but he didn’t stop at the concept stage. He actually printed personalized, functional bracing for a specific user. If you weren't interested in 3D prints before, maybe this is a good incentive to learn more.
