This 3D printer hack could replace your tattoo artist. The automated tattoo machine is an altered 3D printer that creates permanent body ink. Conceived by Paris design firm Appropriate Audiences, the 3D printing tattoo gun follows a very simple process.
The Tatoue involves attaching a tattoo gun on rails to a metal frame in the shape of a square. This contraption can move on three different axes, which allows it to curve and follow the body's lines. After choosing a tattoo design, you load the file into the printer. Place the limb (ideally an arm) into the frame and the printer will execute the body art.
The 3D printer hack also has a sensor that measures the skin's textures and dimensions while in operation.
