If fumes are contained and filtered enough during the main process so I can stay in the room, having to wear a mask only during the preparation and post print manipulation is fine.
Wild idea, buy a resin bottle as smell test. More serious, buy the tiny bottles some shops sell for water effects, it's probably the same kind of chemistry, some brands are probably repackaging translucent UV curing resin at a premium. Expensive test, but not wasted as you can use it for water and other modeling tasks later. Photon, Epax and Elegoo all have mono versions now, but no idea which have filtering.
The smell and toxicity of resins is something I'm already aware, so no need to test (still a good test for those who have no experience with such products). As mentioned earlier, I can deal with the manipulation process by wearing a mask. What I really need to know at the moment is: how effective are the filtering systems that some printers have. Could I continue to spent time in the room without extra care during the printing time ? Unfortunately, I didn't find real practical opinion so far except from @ChrisForrest :(
The filtration systems are useless. "Activated carbon" my backside, it's just grey foam that does nothing. A good seal around the print volume and fans that only circulate air around the UV light source for cooling are the only ways to contain the smell. That's why I don't recommend a printer based solution to the smell, but a resin based one that removes (most) of the smell before it even exists.
I talked to my tenant who has the special booth for his, he apparently has been venting outside as well through a window but has had to stop doing so with the coming of winter.
Just saw that Elegoo is selling portable air filters that are supposed to sit in the cabin of the printer itself to take away noxious gases, would be good to see if that's enough or not
Thanks. I've checked their store and it seems like a decent option. I've found an other filtering solution (a local one by the way) with real scientific background, but it's advertised around FDM and is a complement to an enclosure. I see several pros and cons in Elegoo's solution: PRO: compact can be used in other devices CON: include battery (a feature per se but another extra electronics to recycle in the end) seems a bit small to be really efficient lack formal value regarding filtering standard Thanks to all your feedbacks I've been able to find out more information and came to the conclusion that I won't feel confortable having an 3D printer in my actual home without proper enclosure/filtering installation. I'll try to update the initial post to summarize everything so it may be helpful for anyone with the same questioning. Again, thanks to everyone for all those valuable informations.
I don't really see a reliable way around this other than to vent the fumes to the outside, which is problematic in places with seasons. Even with filtering. Maybe something like the traditional "spray booths" could do? Contain the fumes, filter them, yet still vent whatever is left to the outside? The end result should be no uncontained fumes i guess
That's pretty much my conclusion at the moment. So as such implementation is not easily doable without major rethinking of the whole room (and some extra investment) I'l putt this on the side of the road for a while.
