In any space where you spend a lot of time, I'd recommend an enclosed printer and an air filter or outside ventilation. While the fumes of PLA and PETG are not proven to be harmful, they do contain microplastics that you'll breathe in.
This is also good advice for ABS/ASA and filled plastics. Honestly, I'm way less concerned about PLA fumes than I am styrene or potential airborne microscopic carbon fibers.
so does every plastic packaging of your food.
That's no reason to willingly add even more to your diet/environment
@SaveTheTuaHawk hence it's not recommended to melt your food containers while eating.
