Tinkerers Create Cheap Prosthetic Hands with 3-D Printers



(p. D1) The proliferation of 3-D printers has had an unexpected benefit: The devices, it turns out, are perfect for creating cheap prosthetics. Surprising numbers of children need them: One in 1,000 infants is born with missing fingers, and others lose fingers and hands to injury. Each year, about 450 children receive amputations as a result of lawn mower accidents, according to a study in Pedatrics..

State-of-the-art prosthetic replacements are complicated medical devices, powered by batteries and electronic motors, and they can cost thousands of dollars. Even if children are able to manage the equipment, they grow too quickly to make the investment practical. So most do without, fighting to do with one hand what most of us do with two.

E-nable, an online volunteer organization, aims to change that. Founded in 2013 by Jon Schull, the group matches children like Dawson in need of prosthetic hands and fingers with volunteers able to make them on 3-D printers. Designs may be downloaded into the machines at no charge, and members who create new models share their software plans freely with others.

The materials for a 3-D-printed prosthetic hand can cost as little as $20 to $50, and some experts say they work just as well, if not better, than much costlier devices. Best of all, boys and girls usually love their D.I.Y. prosthetics.
