Hi there, just finished printing my first print with the flexible resin 50A.
To my surprise the inner side of the cover was completely covered by some kind of condensation. When i wiped it off with a paper towel, it felt very oily and it was yellow in color. Is this normal?
I’m afraid this oil is going to go somewhere it shouldn’t
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.
That makes perfect sense. I also print in a cold workshop (14°C) with a warm mat underneath the printer but I think there is a big difference of temperature between the inside and the outside of the printer.
The flex A50 must have more evaporation than the other resins I used and that’s probably why I get condensation issues.
I’ll keep that in mind the next time I print with it.
If you wipe down the inside occasionally with some IPA you should be fine. That’s what I’ve been doing.
Similarly I do get the occasional splash inside the printer. So I wipe those up whenever I find them. Mostly they’re near the resin-dispensing area, but sometimes I see little splash marks on the tops of the print trays.
