A new wave of costume design has hit Hollywood: the Iron Man 2 suits from the box-office-crushing hit were by a 3D printer.

The 3D printer by Object Geometries, to be exact. The Iron Man 2 suits worn by Tony Stark and his enemy Whiplash were fashioned by the film's production company Legacy Effects using a 3D printer that applies an ink cartridge of powered plastic. The result is a super thin layer of plastic, which is then "cured" with ultraviolet light and made pretty with paint.
