Also having a 3D printer. They typically belch a lot of particulates into the air while printing not to mention depending on the kind of hot end you have it can basically be the equivalent of burning a nonstick pan every time you print.
EDIT: This also applies for resin printers BTW just in lightly different ways.








As long as you’re venting it sufficiently you should be good
My setup can change the air in my apartment about 6 times per hour
But mine also runs double duty during the summer time (lease says no AC so it get HOT during the summer) to help cool it down after dark.
