See this thread 10 Micron Print Layers. I posted a settings file for FireCast resin. But read it through.
I bought some Photocentric resin to give it a try (this is the result of my first try: http://socaugusto.azurewebsites.net/3D_Print/Photocentric/Photocentric.html) but none of the standard settings work on my Form 1+. The resin gets overcured. I’m now doing a settings file for their grey resin and will be posting it in the next few days.
Just one final word. Formlabs has expensive resins in comparison with other suppliers and I as an hobyist in Europe find it hard to agree paying approximately 200€ per liter of resin (resin+vat+transports). But the truth has to be said, no other resin that I’ve tried is as easy and has such good results as the ones from Formlabs.
