I’m experienceing a lot more fumes and odor from my new H2D printer than what I had with my A1 printer. I’m using the same PLA filaments that I’ve used before (same rolls). The H2D door is closed and I’m using an AMS2 unit but the odor is not from drying as I’ve done little drying so far. Is this nomal to be experiencing these increased odors. My entire recroom now smells where I’ve used an A1 for over a year constantly with little odor in the room using PLA filaments of several different brands.

This is strange. Is exhaust fan working so air from chamber is filtered by carbon filter? And is it really PLA odour or something else? I have no odour printing PLA or very little on any of my X1C, H2D, A1 and A1 mini. of course there is odour printing materials like ABS/ASA e.t.c. For this case I have placed 250mm fan in my window and that sorted this problem.
Speaking of PLA if you have quite strong odour (if it is not some kind of stinking PLA I haven’t faced yet, or You are printing a very long hours maybe) it could be good practice to check everything there. It could be something else not neccessary PLA

Are the nozzle temperatures different or same? I find the PLA smell similar between my A1 mini and H2D
I’m using the same rolls of PLA that I used before. Could it be that the H2D is pushing air and the air movement is going throughout the room while before my A1 the air was still as it had no exhaust.
Shouldn’t be. Printing principles are the same. As KYZ asked, could be wrong temperatures, but if you are using default profiles, I doubt that. Can’t imagine different odor from the same material if it is melted similar. I cant feel much odor from PLA even when open door and smell inside a chamber. Of course there you will feel some there, but not critical even there. But that does not mean there is zero emissions printing PLA. If it is some kind of a living room, You should make some exhaust system so all this stuff will go out of the room. Melting of any plastic makes toxic fumes, even PLA and even if you cannot smell them. PLA is not that bad, but I would recommend not to risk as no one really knows how it will affect your health in a long time run.

Odd, the first thing I printed was ASA and I smelled nothing (printer is about 2 feet from me in my office) except when it pooped, but for ASA it circulates the air through the filter so that makes sense. I’ve printed ASA, ASA-CF, PETG, PETG-CF, and PLA. So far none of which have left any kind of smell in the office. Maybe your filter is faulty? Unless you’re extremely sensitive I don’t think you should be smelling anything that strongly
May be the printer itself. My A1 and mini both put off a smell during the first few uses, though not very strong. My X1C put off even more of a smell for a longer period of time, but went away after the first week or so.
I printed PLA und PETG-HF and the smell is way less than on my A1 mini.
I have no idea if the filter is used on these materials. I think it can move up and down, depending on the material printed?
For filaments that need a cool chamber, they are exhausted but not filtered. For filaments that need a heated chamber, they are filtered but not exhausted.
People are starting to make filters for the exhausted air, or you can buy an exhaust tube and filter plus print a rear duct, which would do a better job and last longer but also cost more money in the short term.

Just to chime in, I’ve been using Bambu and Zyltech filaments in PLA. I haven’t noticed any smell at all and I’m also printing with it right behind me in my office.
I envy you. When I tried my first ASA print I had to open my windows and eventually even had to leave my room 
It was one of those things I was looking forward to (the filtering) but either some component is missing/broken, or I’m very sensitive to it.
I would open a ticket with Bambu, maybe there’s something that isn’t sealed that’s leaking fumes? Potentially dumb question but are the top vent and louvers on the back functioning properly when you turn the fans on/off?
I mean the poop chute has no seal, or door, it’s just open to the outside. At least on mine it doesn’t.

Yeah not sure, I’ll check those next time.
@BaIto same here, indeed not fully tight that way.
Thanks for looking, glad to know I’m not delusional.
I ended up designing a vent that my window slots into, thought about posting it but I haven’t had the time. It works extremely well and I went from being unable to print the more toxic filaments like ABS (which I primarily print) in my room, to being able to sleep while it’s printing without smelling anything.
Print profile matters too (as well as the nozzle temp) - if for example you are using a profile that makes the outer walls slower, the printed filament will be hotter and emit more smelly chemicals. This could be a reason that the A1 and H2D smell different when printing PLA.
Good to know, thanks! Hopefully I’ll still be able to print ASA when I’m in the same room (yes I know that good ventilation will also be important).
My H2D is located in my office (not large) in somewhat of a confined space. Whenever I print PLA, I get a very distinct order (almost like a burning odor) but don’t seem to get the same odor with PETG. All of my filaments are Bambu. Also, I’ve installed a carbon filter inside on top of the existing filter with the hope of it reducing the odor. It has a bit but not completely.
You know I wonder how effective an attachment for the poop chute that had a big storage compartment for activated charcoal, with a fan sucking air through it and creating negative pressure inside the print chamber would be. The H2D is fairly well sealed all things considered, so you wouldn’t need a considerable amount of airflow. I know this from experience, as my exhaust setup I mentioned in a previous post works very well with the fan on a very low(non-audible) setting.
When printing PLA og PETG the printer just vents stragith out, the filter sits below the fan, and is mostly bypassed when in “cooling mode”. Its a strange decistion by Bambu Lab.
