Update:

Airwolf 3D and Robohand USA have come together to break down barriers and break records. On December 12th, Airwolf hosted a 24-hour print-a-thon in which they broke a recently set record for the most 3D printers simultaneously printing. Letourneau University had recently broken their own Guinness World Record, setting the bar at 158 same-time-same-place 3D printers printing. The print-a-thon shattered the record with 170 simultaneously printing 3D printers, each of which created parts for Robohands. With 201 3D printed Robohands created -- and more finished after the official print-a-thon hours -- Robohands USA now has a stock of prosthetic hands at their disposal, as wella s a $2,000 donation from Airwolf 3D. Robohands USA is teaming up to go to China in February with Water is Life, aiming to create prosthetics for children in orphanages.
