What if you could use a 3-D printer to simply and relatively inexpensively create prosthetic limbs? Jacquin Buchanan is part of an international network of people who do just that -- and they do it for free. The project is called e-NABLE and Buchanan, a software engineer, tells Colorado Matters about the devices, and how he became involved with his work. He recently designed a new arm for an 8-year-old girl named Zadie Wilson of Kansas City, Missouri, and soon will start work on a new device for a child in Denver.
