I am not a doctor but I have been led to believe that heads and brains are important parts of human infrastructure and should be protected. All heads are slightly different, and I am surprised we haven't seen better-fitting helmets come to market. 3D-printed helmets can be used that way. For just over $300, the 3D printing noggin-defenders at Kav will send you a fit kit, a helmet and a delivery van. The company opened a factory in Silcon Valley in order to fulfill orders from all over the United States.
Consumers like the idea of domestically produced goods, but the premium associated with paying a living wage and U.S. regulations act as a deterrent. The recent supply chain snarls have companies scrambling to secure raw materials and inventory at a high cost, undoing decades of just-in-time manufacturing and sparking global inflation. They are forced to make difficult decisions that compromise on speed, quality and costs. "Kav set out to build the world's most advanced helmets, and in the process create a beacon of how manufacturing can excel, not despite labor, environmental and regulatory considerations, but because of them"
There are thousands of helmets per month that can be printed with a solar-powered 3D printer. The company launched its first helmet for $390 back in April, but has since improved production and lowered the price per helmet to $320.

3D-printer, fresh helmets, fresh out of the ov... The image is called Kav
Before opening the current factory, Kwok told me the company was creating proof-of- concept helmets in a garage, but the new lab is stocked with a stack of new tech and custom-made materials to print helmets.
Kwok said that they are on their fifth generation of printers. We have built environmental controls on top of the entire cluster. We use a carbon fiber nylon composite that is formulated for impact attenuation and stability in temperatures from -15C to 70C. There is no other like it on the market.
