Robert Downey Jr. helped a disabled boy to become a real-life Iron Man when he presented the child with a 3D printed prosthetic arm modelled after that of the Marvel superhero. Iron Man actor Downey Jr. was working with non-profit organisation Limbless Solutions to give young Alex Pring – who was born with a section of his right arm missing – the fully functional prosthetic.
Limbless Solutions uses engineering students from the University of Central Florida to create 3D-printed limbs for children, allowing for inexpensive production of prosthetics that kids quickly grow out of. Each limb costs around $350 in materials, and takes up to 50 hours to construct.
Seven-year-old Pring, a Transformers fan, also received an Optimus Prime arm from Limbless Solutions last Christmas.
