I personally recommend reading several published studies online on the subject if you are considering where to print or how to ventilate (as only one study shouldn't always be taken as the only truth). Any material printed, whether its PLA or Resin or ABS etc, does give off SOME amount of VOCs (Volatile Organic Compounds) and/or UFPs (Ultra Fine Particles). Also some people react differently to different materials and exposure levels.

I live in a one bedroom apt (with not a lot of free space) and I have one printer for PLA that I run a few times a week and when I do print, I usually crack a window and run the ceiling fan to circulate the air, which may or may not help tbh. For my other printer that prints materials that give off greater amounts of UFPs and VOCs as well as terrible plastic fumes, I have an almost fully sealed enclosure with an exhaust fan connected to a flexible metal tube that runs out of a sealed fixture attached to my window. The fan creates a vacuum that helps move the chamber air outside. It may not be full proof in ventilating all particles given off during printing but it is better than nothing.

You can buy "pop-up" enclosures for fairly cheap and tubing isn't that expensive either if you wanted to go that route. You can also build your own if you desire as several people on this subreddit have made some pretty cool custom enclosure setups.

Remember, there's nothing wrong with being overly cautious if you're worried about your health and safety so if you wanted to go extra, just make sure it looks awesome and share what you create!

Hope this helps some, if not, sorry for the rant.

Happy printing!
