"Glassomer is a German startup that began its existence in 2018. Their product is a liquid photopolymer resin that can be cured at room temperature to form solid glass, with some post processing.
The company does not intend on producing its own 3D printers, but instead wishes to merely produce the resin, which can apparently be used in any conventional resin 3D printer, either SLA or DLP. These processes involve selectively solidifying the photopolymer with a light source of suitable frequency, layer by layer to form a solid object. "
