Hi, I found the name of the KIT spinoff, it's called Glassomer.

Unfortunately, they have been undercut in terms of temperature. Some guys in the US claim they can 3d print glass at ~200 deg Celsius..

So Glassomer is probably dead in the water (from the POV of VCs) unless they can find someway to beat the 200 deg C record, or to do it without UV.
