The tech is not new and the XY can be scaled. The real work is in the materials. This system requires low viscosity photopolymers in addition to oxygen inhibited curing. It will print trinkets faster but don't expect parts with material performance like ABS, Acetals, Nylon etc to come out of it.

The real trick that they pulled off is getting the $41M in venture. It was done in stealth mode to not alert the public for feedback that they would have received about how it's not novel.
