Print Your Own Prosthetic Limb

3-D printing drops manufacturing costs precipitously, as it makes possible an entirely new prototyping process. Previously, invention was a linear game: Create something in your head, build it in the real world, see what works, see what fails, start over on the next iteration. This was time-consuming, creatively restricting, and prohibitively expensive. 3-D printing changes all of that, enabling ?rapid prototyping,? so that inventors can literally print dozens of variations on a design with little additional cost and in a fraction of the time previously required for physical prototyping.
