Hexo Helmets releases custom 3D printed bicycle helmets with optimized impact resistance

Hexo Helmets, a London-based technology start-up, has announced the commercial availability of its custom 3D printed bicycle helmets.
Made from Polyamide 11 using SLS, the helmets incorporate honeycomb structures designed with the cyclists head shape, to create the most lightweight, and protective headgear. According to Jamie Cook, founder of Hexo Helmets, Foam’s pressure response is limited. There are only a few variables to play with: it’s quite basic in that sense.
We’re 60 years down the road with foam helmets - and even though they’re only 30% efficient at absorbing energy, we’ve pretty much done everything we can do.
