I’m much more scared about the solvent glues. They contain some /nasty/ things and will as happy dissolve the fat under your skin as they will the plastics. There’s a reason they work so well.
Also; HEPA filter will /not/ stop any of this. You need activated carbon. Build or buy a solder-fume-extractor and put it close to your printer if your worried or an enclosed box through carbon. HEPA will only get rid of dust.

@Electra_Flarefire Acetone probably is the least concern - it’s generally recognized as safe and while you probably shouldn’t wash your hands with it (i know some Chemists who do) or inhale a large amount of its fumes, it’s not going to cause any real harm, even if you don’t really care about handling rules.
Of course, some of the solvents used for PC or PLA are quite a bit nastier and should obviously not be used by a hobbyist.

@Thomas_Sanladerer I was thinking about PLA/PC/etc glue. I’ve got a tube on my desk with this set of ingredients: https://lh6.googleusercontent.com/4x5KnIzGWBAQj2BF9K6qKpUE1sULI2zB_xfOtNmbpbyR=w793-h754-no
Not the nastiest stuff in my shop, but I wouldn’t want to get it on my skin in any real amount.
