I'm so glad that fad is over. My mother worked as a theatre artisan before retirement and it was, among other things, fumes from curing epoxy that caused numerous health issues down the line.
I am curious about the down-the-line effects of fumes from printing PLA and PETG. Reddit posts suggest no ill effects, but it hasn’t been long enough in the hobbyist world.
My printer is near a window so I just added an exhaust duct to the window, in the past when it wasn't close to a window I ran that duct through some filters (charcoal, furnace filter stuff) and left the end near an additional air purifier i had in the space.
