Lower cost printers are absolutely using LCDs with an LED UV light source. These resin curing printers are pretty darn cheap as well, and have a ton of resolution. They also excel on volume as they do expose the entire plate at once and don’t require scanning a laser around.

The material you get out of such a printer is of course entirely different from an injection molded part.

Yeah, I’m a pretty big 3D printer enthusiast. I’m surprised they shifted from lasers to LCD. I guess the laser and galvo setup was too expensive. Probably also easier and cheaper to ship new “Low Force Display” for people with formcare. End of the day, no matter what these vendors say, the crystals in LCD get damaged by UV light and would need to be replaced eventually.

It also opens up a whole bunch of material options. If you go to resin providers websites they have only a few resins for laser printers and tons and tons for lcd printers.
