These are the mold files to cast the helmet in urethane rubber (PT Flex 85). I desgined three kinds of molds. A version with two-part rigid molds (for silicone or urethane casting with shore below 60), a version with hybrid molds (front half in silicone, back half printed resin: perfect for urethane casting) and a new never before seen version that I call the Instant Mold. Imagine making the silicone parts at the same time using the same resin print? Crazy right? Making molds 8 times faster is now possible thanks to my methodology.
