In our last post on using software to make a more protective helmet, we discussed how we engineered a lighter helmet that's more protective. The foundation for the best-performing hockey helmet is a combination of superior materials, software, and hardware. Thermoplastic polyurethane (TPU), with its energy-absorbing properties, is the raw material making up our helmets. Our software is literally the brain that runs the show taking all the customer measurements and personalization requests and translating that into work for the printers. KAV defined hardware fabricates the helmet. Today, let's explore the 3D printers we utilize to make a KAV Hockey Helmet.
