Lately I’ve been using inland brand natural Pla. It prints so nice and I find that it adheres to the print bed really well. My go to filament brand used to be Amolen but some of these cheaper filaments have gotten so good in recent years.
Matte resins definitely print nicer in my experience. I haven’t tried too many SLA resin bands I mostly just stick to Siraya Tech fast resin because it’s low odor. When you blend your resin do you put it in a new bottle every time or do you reuse bottles?
Reuse the bottle of the base resin. It’s mixed from base epoxy resin with additives and pigments. The issue in particular is caused by the pigments and with no good solution as everything you can do is slowing down the process. A printer that circulates it without dead spots could fix it but you might run into issues where it “sticks” to the FEP making it worse. An upside-down SLA printer could resolve the issues but they are rare and expensive. After all there probably was a reason why you can’t buy it. You can do more stupid mixtures/washing/curing for example an soft-touch surface with a hard resin but they all fail in some regard making them not feasible (that particular had just awful mechanical properties. Worse than expected.).
