4-Year-Old Gets 3D-Printed Prosthetic Arm in Ironman Colors

Just in time for Christmas, 4-year-old Hudson got a very special present: A prosthetic arm, created with a 3D printer.

The type of printed out prosthetics are inexpensive alternatives to more costly traditional ones.

Hudson’s new arm is red and yellow – reflecting his hometown Kansas City Chiefs and, of course, Iron Man. But the superhero has nothing on this dynamic kid.
