Permanent tattoos inked by hacked 3D printer
During a recent electronics workshop at the ENSCI-Les Ateliers design school in Paris, a group of students decided to swap a MakerBot's extruder for a pen. Within a few hours, they had modified the printer to draw simple, short-term doodles on skin. Not satisfied with temporary tattoos, the students added parts from a standard tattoo machine. The result: a printer that can give you permanent tats.
