It seems that 3D printers can be used to create just about anything, from fully functional guns to super skittish robots. And 3D printers could be the solution for amputees in developing countries too, thanks to the work of 17-year-old Easton LaChappelle from Colorado.
Looking to some free online resources, he has used a 3D printer to create a fully functional prosthetic arm and hand that comes with robotic technology. The hand can grip and hold things; even cooler, the 3D-printed robotic prosthetic arm can cost less than $500 to make. By comparison, a state of the art prosthetic worn by a seven year old girl he met at the 2011 Colorado State science fair costs about $80,000.
