This Mobile 3D Printer Uses Plastic Cups as Printer Ink

3D printers started out big and bulky and like everything else in the tech world, have gotten smaller; this mobile 3D printer is the first of its kind, but certainly won't be the last. This 3D printer is housed inside of a bicycle and uses old plastic cups as ink.

The machine still looks quite big but given the fact that it's being carried on a bike, it's light enough. The bike breaks down old plastic cups into a powder that is then used as ink. The ink is then turned into gear-shaped tokens that are used as bike spokes.

This mobile 3D printer shows how 3D printers can be used in an ecologically conscious way.
