3D printing, prosthesis and the third world

In November 2013, Ebeling travelled to Sudan for a month, hoping to find Daniel and build him an arm. He took with him printers, spools of plastic and cables. The 3D printers that create the prosthetic\’s plastic parts make the device seem hi-tech, but the resulting arm is really just a simple, mechanical device. The arm works by using movement to trigger cables, threaded throughout the plastic structure like ligaments. When the user flexes and bends the remaining portion of their arm, this motion tenses the cables, which in turn curl and uncurl the fingers at the tip.
