Why wear a prosthetic when you could become a superhero instead?

3D printing and design expertise enabled six children with upper-limb differences to build prosthetics that gave them superpowers

In a hidden room in the back of a pier overlooking the San Francisco Bay, a young girl shoots glitter across the room with a flick of her wrist. On the other side of the room, a boy is shooting darts from his wrist - some travelling at least 20ft high, onto a landing above. It feels like a superhero training center or a party for the next generation of X-Men and, in a way, it is.

This is Superhero Cyborgs, an event that brings six children together with 3D design specialists and augmentation experts to create unique prosthetics that will turn each child into a kind of superhero.
