‘Iron Man’ actor Robert Downey Jr. has partnered with Limbitless Solutions to give an amazing new bionic arm to 7-year-old boy who was born with a partially developed right arm.

Alex Pring, a boy from Groveland, Florida who loves superheroes and riding his bike, was taken to an Atlanta hotel room by his family and a camera crew where he was surprised by none other than Robert Downey Jr. who presented him with a real working ‘Iron Man’ bionic arm.

The whole thing is a blast to witness what with Downey acting in-character as Tony Stark to Pring who is clearly astonished to meet the charismatic ‘Iron Man’ actor. After the meeting, Downey went on to describe Pring on his Facebook as “the most dapper 7-year-old I’ve ever met.”

Pring’s ‘Iron Man’ bionic arm itself was developed by Limbitless Solutions, a volunteer group that specializes in building and donating low-cost 3D-printed bionic limbs to children around the world. The group was created by Albert Manero, a Fullbright scholar and doctoral student in mechanical engineering at the University of Central Florida.

Through the power of 3-D printing technology, Pring has been given the chance to be able to make use of his missing limb. He received his first arm from Limbitless Solutions during this past summer, but then had it upgraded to resemble that of Optimus Prime from ‘Transformers’. To say the least,  it looks like this new ‘Iron Man’ arm is definitely a nice step up.

The meeting was organized by The Collective Project, a social media campaign organized by Microsoft to celebrate students using technology to make positive changes for their communities.
