3D printing is making it possible for even college students to develop advanced devices that would have previously taken a lot more effort to design and prototype. Thirteen-year-old Sydney Kendall, a girl who lost her arm in a boating accident, got a new custom made, 3D printed arm with individual fingers and a novel control mechanism. Unlike other prostheses, the new device created by engineering students at Washington University in St. Louis, uses an accelerometer attached to her shoulder to detect its movement. Different movements of the shoulder trigger different movements of the fingers of the hand.
Here’s a video report from Fox2 News St. Louis:
