Hi, I'm a young athletic amputee involved in several sports. I'm also a mechanical engineer, so prosthetic design is near and dear to me. My insurance typically doesn't cover sports prosthetics so being able to 3D print them would be a dream. I am however an above knee amputee so I'd be putting considerably more weight and stress on a prosthetic than an arm amp. I'm in need of a better/different snowboarding knee and foot. Given the application, it would need to be strong enough to handle jumps and also be made of a material that won't become brittle in the cold (for instance, all tests with carbon fiber have failed). I haven't done any research, so forgive my ignorance, but is this even possible?
I'm also in need a rock climbing foot. That should be much simpler.
