Watch Robert Downey Jr. Present a Bionic Iron Man Arm to a Disabled Boy

My HERO!!

ROBERT DOWNEY JR. personally delivered a legit, bionic arm . . . styled to look like one of Iron Man’s . . . to a 7-year-old boy named Alex who was born with a partially-developed right arm. The 3D-printed arm was created by a company called Limbitless Solutions, who are on the cutting edge of making this technology cheap. This particular arm only cost $350 in materials.
