Gosse Adema has used LEGO to build a fully functional 3D printer that creates sculptures out of chocolate – and a step by step is available for those who would like one of their own.
The project was originally begun as part of a Remix 2.0 contest for improving existing designs on the Instructables website. The result is an improved version of a decade old device created by a user named Saul, and includes the addition of a chocolate extruder made from a basic syringe.
Check out the demo video after the jump.
