It is, but you still regularly see people showing off their latest 3d printer which is sitting in a kids bedroom running all day, or their office.
Often when questioned, the existance of it being in a case or there being a cheap air purifier in the corner of the room is cited as the reason why its 'fine'.
I do feel like we dont really have sense of effects of particulate matter on the body. How does the risk of this compare to walking down a street with lots or running ICE cars? Or when you go into a basement and can smell the natural gas burning - is that a similar risk?
If you told me being in the same room as a PLA printer was 10x worse I would believe it. If you told me being next to a car for 5 seconds was 10x worse I'd believe it. As far as I've read we dont have great metrics.
We really do not have a sense of these things. We are often overconfident in our limited senses. I was being poisoned by carbon monoxide from my oven and did not realize it until it was too late. I told myself "it cannot happen to me". Thank God for a few related HN comments, and a hunch to buy a CO meter.
Tires yes, but since EVs use regenerative braking at least some of the time I would think they'd be slightly better in that regard. Regenerative braking does not engage the brake pads.
