I would love a dedicated air purifier or ventilatuon system for our 3D printers and laser engravers. For now, we get by with open windows and doors as we are getting ready to move and not using them much.
I have a pyrography machine, and I sometimes have to sand clay, resin, or wood. I usually just wear a mask and open the windows when I’m burning. For sanding, I go outside, but still wear the mask. I don’t like to sand in the house because dust gets everywhere.
It helps clear the air I have had them in my house so it was just moving one near by and letting it filter the air like normal while using the engraver.
I use an air purifier because of sublimation fumes and epoxy resin and laser iengrave vents out window with the covered bundle . However I would much rather have a fume extractor so I wasn’t so limited to where machines had to go to vent!
