3-D Printing Gives 11-Year-Old Boy a New Hand

Eleven-year-old Felipe Miranda rides his bicycle using both hands - one of which is a prosthetic. But it’s not a conventional prosthetic. It was created here - in a studio in Buenos Aires where industrial designer Gonzalo Sanchez and his colleagues rent 3-D printers to create all kinds of objects, using plastic, metal and other raw materials. But before Felipe’s mother contacted them, Sanchez says, they'd never created a prosthetic hand.
