I do notice variable amounts of condensation in the printer, and it depends a little on the resin type I use, although I’ve never used 50A.
What’s the room temperature like when you print?
My guess is if there’s a big differential between the temperature inside the printer and outside, that would increase condensation. I don’t know what part of the resin evaporates, but clearly a little bit does. I wonder if anyone has any insights into that.
I print in a cold garage, but I have a small space heater under the printer, so it’s mostly engulfed in a warm cushion of air. That said, the front of the printer remains fairly cold and that’s where I get the condensation.
