Hi, We currently have ultimaker S5 and we will be getting in a week two new H2D combo’s. I am a bit concerned about fumes and particles… Has any one used some air purifiers and got good results ? Currently our printers are located in an inner room like an internal or parallel corridor. It is no…

I would prefer venting the chamber directly rather than polluting a larger area.

You’ll be hard pressed to find a purifier capable of filtering the resin byproducts from the air. Most high-end air purifiers can only capture down to 0.3 microns. Some will claim down to 0.1 micron but I have doubts on that based on their price. Even so, that’s not enough to extract all the resin b…

I’m having difficulty imagining what “resin smoke” even is but I am sure FDM printing doesn’t emit any.

Most of that stated particle size that shows down to 0.1 to 0.3 micron is the HEPA filter in the air filter. The activated carbon in the filter is what is going to pull those smaller particles out. So when you’re talking fume generating stuff which are generally particles you cannot see, you need a …

Check out the better filtration thread. Lots of filtering stuff in there.

Can you provide a link to the thread you’re thinking of? I searched “better filtration” and got a lot of threads that don’t appear to be it.

I think this is the one… [image] H2D Air Filtration Upgrade Bambu Lab H2 Series So the info page for the H2D shows a 3 mode air filtration system. [Active Air H2D] Unfortunately I have not seen mode 3 yet, only 1 and 2. When printing filaments that dont require chamber…

Yup, that’s the one. My bad for calling it the wrong name lol.

Im going to share something extremely stupid that I did. I once printed a vase that leaked water, so I coated the inside with resin. It was taking forever to dry, so I put it in a heated and filtered printer to dry. I was thinking it would stay somewhat contained for the short time thatbI planned on…

The issue is that activated carbon filters become saturated quickly, especially when printing materials like POM that emit formaldehyde. For an 8-hour print in a Bambu Lab H2D with an actively heated chamber, I allocate approximately 250–300 grams of high-quality activated carbon to effectively ads…
