Albert Manero started a company that creates bionic arms for needy children using 3D printing technology. Microsoft and Robert Downey Jr. were inspired by Albert, so they teamed up to make a special Iron Man-themed bionic arm for one special boy who was missing an arm.

This is awesome on all levels.

Alex was born with a partially developed right arm.

They meet and shake hands first.

And Alex puts on his new bionic Iron Man arm.
