I am printing the parts now for a small SLA printer (how meta). Uses a UV LASER rather than a projector. If we like it I will upgrade to a projector (larger) one at some point. This one I can use with Simplify3D given how it operates, sadly they don't directly support SLA layer-at-a-time directly. The LASER for the SLA is the most expensive bit (I have the parts for a LASER engraver too and the 5w LASER for that is really not cheap). Always new things to build. I'll post some pictures.
