        UV resin, basically, just super high resolution that makes it incredibly expensive (even the cheaper models used for quick check measurements by dentists cost $20k+ - that is, latest tech, brand new from manufacturer, before someone drops a link for a used unit from 2018 for 10 grand). But the sheer volume makes up for it, a single printer like that can be generating pure profit within a year.

          Incredible, and thanks for the reply.

          I was thinking it had to be a resin printer. What I thought was curious was the potential for bacteria in the layer lines, I guess with this type of printer, whatever proprietary material they’re using (lol), and the proper sanitation methods, it’s probably not an issue.
