Thermoforming is a process that has been around for a long time, used frequently for the creation of molds. A sheet of plastic is heated until it becomes pliable, at which point it's formed into a mold. It's a common industrial practice, but Robot Factory has designed a personal thermoforming machine that can be used in smaller settings for small-batch production. The 3D FORMING system can be utilized to create either molds or finished 3D objects, and it's a simple method of turning 3D printed objects into molds.
