Another possible location is in the front, where we do woodworking, and can open the garage doors and windows, but, of course, we have to deal with sawdust in that room.
People have very different opinions on this. Some people claim they can't stand the smell, some people claim they can't sense it at all. Personally I don't mind the odor, it's just plastic-chemical if that makes sense. From a safety standpoint there hasn't been a lot of research (that I am aware of) into the volatiles that off-gas during SLA printing. The safest bet is to keep it in a ventilated area and away from living space so that you aren't spending a lot of time inhaling around it.
One thing to keep in mind is that resin printing is sensitive to the ambient temperature of the room. The resin vat should stay at or above 65*-70*F. If you go lower than that the resin curing is inhibited and the resin itself may separate during the print.
Thank you! Glad you mentioned the 65 - 70 degrees, as we usually keep the wood shop and back room below that in the Winter. It's the same issue we had using epoxy with fiberglass on the teardrop. We eventually bought an electric heater so we could work with it in Winter. If Shelly ends up doing a lot, we might have to invest in a propane heater to cut our heating bill.
