I’ve been doing resin printing in my shed since the spring and so far (fingers crossed) it’s gone just fine. I prefer doing it out there because I don’t want the fumes in the house.

I very recently did a print when it got down in the low 30s and it came out fine. The one nuisance was cleanup, as cold resin flows very slowly through a paper filter. I am not sure I’d want to try it in the low teens, but it may work.

A couple of tips that might help you. I purchased a “brewer’s belt” on Amazon. It’s basically a rubber belt that you plug in and it provides some heat. It doesn’t get super hot or anything, but warm enough to really help. I wrapped my UV shell in a mylar emergency blanket (which may not be necessary, but it helps protect the plastic shell). I then loop the brewer’s belt over this. I then put the box that the printer came in down over the whole thing when it’s printing. This combination has done a good job of trapping some heat inside the print area, and I have very few print failures. I run it this way in summer and winter.

I do think by storing everything in the shed I am probably accelerating the wear and tear on my equipment. As you probably know, the screens will fail eventually (they burn out) and I’m guessing being in the heat and cold is not good for electronics in general. However, it’s worth it to me to keep the fumes outside. After a print is done, I open the shed to air it out and barely smell anything at all.

Another tip, you may want to tape some butcher paper or similar over the shed windows, if it has any.

Edit: here is the heat belt I use.
