Emissions will go down, no? Also depends on the filter somewhat, I guess. But from how I understand it, the emissions aren't that high to begin with. Of course breathing in metal nano-particles from filaments with additives doesn't sound that healthy...
I think it would go down, but by how much? And is it significant enough to remove the requirement to vent outside?
I wrote a review article summarising studies about emissions during 3D printing: https://doi.org/10.1016/j.atmosenv.2022.119501 (Should be open-access soon) Basically you can say: - Small particles and gaseous (Volatile organic compound - VOCs) are emitted during 3D printing - these emissions can be harmful if inhaled - higher temperature results in higher emission - ABS probably more harmful than PLA --> recommendat…
What impact does an enclosure with a filter have on the emission of particles and VOCs?
I recently purchased a 3d printer, and I looked for articles talking about the risks associated with PLA fumes. This article[1] seems to be popularly cited, which includes the statement "PLA doesn’t look like a problem." I think this is what in my experience has been largely the sentiment when I have asked around, and read forum posts about the topic. At my local library there is a makerlab space, they are free to us…
I know that if I print PLA and stay in the room, it will give me a headache after a while. And I can definitely smell it, so at least something is getting released into the air. I don't know if that actually means it's harmful, but I stopped staying in the same room if a printer is running.
Also, when I first got my printer, I had it running in a corner of my office room and found I would reliably get a sore throat after a few hours printing. It’s now shifted to the basement with a extractor fan nearby.
(2019)?
There's been a concerning trend of people running these in bedrooms and offices with no filtration, and others thinking they can cobble together their own filter using a bag of carbon, generic hepa filter and a PC cooling fan.
I figure the more information on the volitility of the materials that can be spread the more people it will get through to that you really should not be running a 3d printer in your home at all unless its in a sealed, outdoor vented enclosure. Most people running these things dont even have a basic room air purifier.

I have a laser CNC, which has a built-in fan that is not quite strong enough to move both the smell and the particles out the exhaust system. I bought a pretty cheap dryer-vent blower fan and added it to the exhaust tube. With the addition of this fan, the particles and odor are sucked out sufficiently. Previously the smell of cut particle board and acrylic were so bad, I considered returning the machine. The busines…
Nice, I have a pretty similar setup but don't have the reservoir, what are you using for that? My issue is that the CNC uses a drill bit so i get much bigger chunks/dust than the ultra fine particulate i get with the laser/3d printer
To your point, the laser doesn't produce particles that are the same size a brill bit would (larger pieces sit pretty on the bed until they are lifted away) but I reckon it might still help!
Just spitballing, but would a setup that swaps the dryer-vent-fan for suction on par with a Shop Vac be able to move those larger chunks? (add water to the Shop Vac's belly before using it as extra filtering)

In 3d printing circles and even 3d printer instruction manuals this has been written for years now... PLA is worse material (especially in regards for UV), but can be done inside, while ABS needs a heated surface and emits poisonous gasses so it should be done in separate ventilated areas (same for resin printers).
Don't dismiss PLA. It is a great material, it is strong, cheap and easy to print. Its greatest weakness as far as I'm concerned is heat resistance. But there is a trick! You can anneal PLA in an oven, which will give it heat resistant properties similar to ABS, maybe a little better. It can be done with regular PLA, but the print will deform. If you don't need a very precise part, it can be sufficient, you can also c…
