Please, use adequate ventilation (with a heat exchanger if you need to keep A/C in the room) if you're going to be resin printing inside. I don't want to see all of you guys get cancer from this hobby.
Even if you're printing with anything but PLA, you should be ventilating well, since it obviously releases chemicals into the air -- you can smell it. PLA does as well, but from the smell it seems like a much different one.
