About this video

In this video Emiel shows that, with a good 3D print in the right material, you can easily print a mould to cast polyurethane in. With hard moulds like these, we recommend using a flexible casting material, such as the flexible PU used here.

Hard materials are possible, but they may be difficult or even impossible to demould without damaging the mould.
