3D Modelling for Molding and Casting using FreeCAD

This video will help you to get started with 3D modeling a one-sided mold for the Fab Academy molding and casting assignment. We follow a 3-step process here where we create the final model first (1), then the negative mold (2), and then the wax positive (3). To reproduce the actual model in real life you would then work in the opposite direction:. Mill the wax positive (3), cast a silicone negative with it (2) and use it to cast the final piece with liquid plastic (1).
