“Dawson Riverman’s parents tried to help him make the best of it. Born without fingers on his left hand Dawson struggled to perform even the simplest tasks… The Rivermans could not afford a high-tech prosthetic hand for their son… Then help arrived in the guise of a stranger with a three-dimensional printer.” J.

Excerpt: 3-D Printing Prosthetic Hands …Anything but Ordinary, By Jacqueline Mroz, NYT
“He made a prosthetic hand for Dawson, in cobalt blue and black, and it did not cost his family a thing. Now the 13-year-old can ride a bike and hold a baseball bat. He hopes to play goalkeeper on his soccer team… 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…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.
They are not designed to look like replacement parts. One popular model, the Cyborg Beast, looks like a limb from a Transformer.
The Raptor Hand and Talon Hand 2.X do not suggest disability; they hint at comic-book superpowers. And they are not made to be hidden — indeed, they can be fabricated in a variety of eye-catching fluorescent colors, or even made to glow in the dark…
These days, some leading experts in 3-D design are now collaborating with E-nable on improved prostheses for children. The hands are lightweight, less than a pound, but the fingers move together, not separately.
Health care providers are beginning to take note. In September, Johns Hopkins Hospital in Maryland and E-nable hosted their first 3-D printing conference involving the medical community, volunteers, recipients and manufacturers. The hospital has purchased a 3-D printer and has begun printing free prosthetic devices for children.”
