Iron Man Just Got Even Cooler [VIDEO]

Are you a Robert Downey Jr./Iron Man fan? You'll be an even BIGGER fan now. RDJ 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. "Tony Stark" brought the prosthetic in a container marked "Stark Industries" and even had an Iron Man gauntlet for himself so that the two could try on their arms at the same time.

Alex's 3D-printed arm was created by a company called Limbitless Solutions, who are on the cutting edge of making this kind of technology affordable. This particular arm only cost $350 in materials.
