Liam, a 5-year-old South African boy, was born without fingers on his right hand due to amniotic band syndrome. But with the help of his own 3D-printed fingers, he can perform precise movements like picking up coins.
Richard van As, who lost his own fingers in an accident, developed the 3D-printed prosthesis called Robohand.
"I can pick up stuff," Liam says in a Robohand video. "I can throw a ball."
Robohand consists of a gauntlet, hand cap, and fingers 3D-printed on a MakerBot Replicator 2. It has simple functionality: when the wrist is bent, a series of cables retracts the digits, allowing the user to grasp objects.
