Also new information about alternate heating elements and methods of construction. 15 chapters include tips on using the machine, selecting a plastic, mold making and using 3D printing for molds. Build a low cost machine that matches the performance of commercial equipment. Great for crafts, scale modelers, makerspaces and even small businesses.
