An inventor has unveiled his plans to revolutionize the health industry by creating prosthetic limbs using a 3D printer. The NHS currently has to pay around £70,000 for a prosthetic hand for an amputee. But robotics expert Joel Gibbard, 23, has come up with a genius alternative which would cost just £600.The first-class engineering graduate has created The Dextrus hand, a fully-working prototype built using a 3D printer. Dextrus works like a human hand, using electric motors instead of muscles and steel cables instead of tendons. The 3D printed plastic parts work like bones and a rubber coating acts as the skin. It takes around eight hours to print one off.
