How hot is too hot for resin printing? - Lemmy.world

I’m expecting my garage where I print to get well into the 90s on some days this summer.

That should be fine. Cold temperatures are actually worse for resin because it slows down the curing reaction. I can’t imagine you’d have problems at any temperature below maybe 120°F.
One addition- sunlight is very bad for resin printers, so if your garage has windows or you routinely keep your garage doors open keep this in mind.
