What do you get when you combine prosthetics and 3D printing? In this inspiring talk, 17-year old Easton Lachappelle shows us how he has been using new technologies to print and build cheaper, customizable prosthetics that could change millions of lives.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
