Experiments in Multi-Material 3D Printing

In this CNC Kitchen video, Stefan shows how you can incorporate two different types of materials into the same 3D print.

For purposes of this demo, he prints a clothes hook where he over-molded a PLA part with a foaming TPU (Thermoplastic Polyurethane) part which creates a protective pad beneath the hook. He uses an E3D tool changer for the multiple filaments.
