Teen Uses 3D Printer to Make Robotic Prosthetic Arms for $500
It seems that 3D printers can be used to create just about anything, from fully functional guns to super skittish robots.
And 3D printers could be the solution for amputees in developing
countries too, thanks to the work of 17-year-old Easton LaChappelle from
Looking to some free online resources, he has used a 3D printer to
create a fully functional prosthetic arm and hand that comes with
robotic technology. The hand can grip and hold things; even cooler, the
3D-printed robotic prosthetic arm can cost less than $500 to make. By
comparison, a state of the art prosthetic worn by a seven year old girl
he met at the 2011 Colorado State science fair costs about $80,000.
The 3D printed arm by LaChappelle can be controlled using an EEG
headband, which measures brain waves. The user will likely have to get
used to the interface and there will be a training period, but that’s
pretty amazing for less than 500 bucks. The actual movement of the arm
and fingers is done through a combination of fishing line and servo
The Colorado teenager showed off his 3D printed arm at TEDxMileHigh.
