Probably the way to deal with this is to have an exhaust system which keeps the build chamber below atmospheric pressure. Exhaust through a water air filter.[2] Water air filters work well on particles, but you have to keep dumping the dirty water and adding fresh water. They're not used much in HVAC or vacuum cleaners because they take a lot of blower power, but for a small 3D printer, where you're not moving much air, they should work.

Thanks, we changed the URL to that from http://pubs.acs.org/doi/abs/10.1021/acs.est.5b04983.


That redirects to "http://pubs.acs.org/action/cookieAbsent", probably because I'm blocking some cookie or tracker. That's a bit much for the American Chemical Society, which is supposed to be an academic organization, not a source of clickbait.


Yes but then aren't you polluting the water? Where are you going to dump the water? Recently legislation was passed to ban micro particles from abrasive soaps and creams because they ended up in the water supply from people flushing them down the drains.

This does not seem like a real solution, it only moves the problem somewhere else.


"Microbeads" are generally from 10 micrometers to 1 millimeter in diameter. [0] Ultrafine particles are less than 100 nanometers in diameter. [1] So while there could be environmental effects from ultrafine particles, the analogy to microbeads isn't necessarily correct.

There's biodegradable ABS [1] but it's not clear that it would degrade much in water.

"The initial approach was to fabricate an acrylic hood that would be placed above the urinalysis workstations and would vent odors directly outside. However, city officials would not permit the laboratory to ventilate the captured air to the outdoors. This prompted Vantari and the IQAir team to focus on air filtration instead of ventilation."


Is that site run by IQAir? That reads like a PR.
