Blogger Turns 3D Printer into Tattoo Machine

A blogger transformed a regular 3D printer into a tattoo machine by replacing its head with a needle and modifying the software. As a result, the device, named Sharpie, was able to automatically apply perfect tattoos. To test the invention, Amy persuaded her friend to get a trial tattoo. His leg was secured for accuracy, and the printer inked the word LEG on it. The outcome was perfect.
