Jon Schull discusses low-cost 3-D printed prosthetics

It’s estimated that one in 2,000 children are born with a hand or arm abnormality, but the cost of a mechanical hand or arm can be prohibitive for children who will quickly outgrow them. Now, with just $10 to $20 worth of plastic, 3-D printers are being used to create fully functioning mechanical hands or arms for children. Jon Schull is a research scientist at RIT and the co-founder of e-Nable, an organization dedicated to connecting 3-D printers around the globe to those in need of a hand, literally.
