That’s the amount of time it takes to make parts for an award-winning robotic hand on a 3-D printer, the BBC reports. Joel Gibbard of Open Bionics says he can use a sensor on his tablet to size an amputee in minutes, print the parts in about 40 hours and fit them together in two hours. The prototype earned Gibbard the James Dyson engineering award, which carries a $3,500 prize and the chance to win the $45,000 international title.
