We tested various plastics for the enclosure and ended up with a Polycarbonate blend being specified for its molding ease, its durability particularly to shock and abrasion. In order to design the eye cups we had a 3D scan produced of users head (aggregated from the control group). The material we specified for the eye cups was medical grade silicone, which were initially vacuum cast in ABS molds to test fitment to a control group. The client required working prototypes for a photoshoot and tradeshow within 3 weeks of our initial consultation. Needless to say we delivered on time and on budget.
