People are saying 'ventilate'. Makes sense. I've got a resin printer in a large room with a crossbreeze, but I'd like to put in some more forced ventilation. Is there a quick thing I can buy that's got a small hood, inline fan, and waste vent? Or do I need to cobble something together myself out of flexible tubing?

Is a portable hepa filter sufficient? I don't even know what to look for.

For my resin printer setup I bought a mylar-covered grow tent from Vivosun which has all the hookups necessary for an inline fan & carbon filter. I zip it up 95% of the way so it's negative pressure and pulling the fumes through the filter.

I can't smell anything after the filter—not even the 99% pure IPA which smells much worse than Siraya Tech Fast resin—so I don't bother venting outside when it's cold out; it vents into the unfinished basement side room.

I wear a respirator, thick rubber gloves, treat every surface as "hot," and UV cure all my paper towels and anything that resin touched.

My Ultimaker sits on the desk in my office and I mostly print on it at night. It doesn't get much use.

I'd start with a cheap kitchen rangehood, ideally with carbon filters (in Australia that's under $AU200) and either vent it outside to poison your neighbours or bang an air purifier on it. Sheets of perspex or light plywood as walls and you're good to go.

I'm way more up on the filtration side because I live in the land of bushfire smoke and 3D printers appear to be particulate problems too so I would try particulate filtering first because it's easy.

The box filters used in aircons and central heating work fine for this, but you probably need another fan to suck on them, not just the rangehood blowing.

Jeez, mate, there are better ways .. put in some lavender (or other scented prolifically growing dense foliage plant), divert some grey water (kitchen sink, bath, etc) to drain through that .. and vent through the bush.

It's like a self cleaning sweet scented air filter that traps particles and only gets better with time.

(And you can tell everyone it's advanced biotech).

HEPA filters will filter out particulate but doesn't help with VOCs. For that you need carbon filters.
