Actually, lots of 3D printers have a box in which the process takes place, so the temperature stays relatively constant, both in time and through the piece being made.

The study reported that even the tested devices which were enclosed still emitted plenty of VOCs: "Interestingly, the presence of an enclosure only moderately reduced UFP emission rates from the MakerBot–ABS combination, with a ∼35% reduction in the median emission rate (although this variation is within the estimate of uncertainty). Larger reductions were not observed, perhaps because the enclosure was not completely sealed and large gaps were visible. While these two comparisons provide preliminary data on how printed shape and presence of an enclosure may impact particle emissions from 3D printers, no other definitive conclusions can be drawn given this limited data set."

  Many enclosures are not fully sealed. It makes a huge difference if the enclosure is air tight.

If they're "ultrafine particles" you'd think they'd just blow around once the cover was removed think dust in a sunbeam. My father has a lung disease called IPF (terminal) which is scarring of the lungs it occurs over time from various particles. He was a blue collar worker exposed to various fine particles; sawdust, welding fumes, grinding metal, paint, probably some asbestos insulation etc. at his place work over the decades which caused small amounts of damage each year. Lungs are not to be messed with they're so delicate and lung cancer isn't the worst fatal lung disease you can get.

  The very small stuff doesn't blow around like dust. For one once they stick on to something they're very hard to remove. Unlike normal "dust" you can't wipe them easily or blow them away.
