My first thought when I read the thread title was, "you can't 3D print skis, multiple materials can't be used in one output, and you can't use metal or wood."
this company did come up with a unique application for 3D printing, but I know they wouldn't handle the abuse most people on NS put their skis through.
the plastic core ski reminds me of the old solly foam-core skis. gaper could ride them, maybe this will be a cost effective way to build price-point skis... time will tell.
and you can tell the company is full of engineers, those skis are visually horrendous... at least the board from signal is cool looking, even if it is an expensive equivalent of this guy:
