> Enclosed with filter for ABS fumes etc.
I agree that the Bambu printers are as good as it gets for plug-and-play printing, but I wouldn't trust the tiny carbon filter for toxic fumes in an indoor environment.
The better VOC filters use a larger amount of activated carbon and they recirculate a high volume of chamber air inside the chamber.
Activated carbon also needs to be replaced over time as it loses capacity to adsorb more VOCs.
Their printers are also not sealed well. See for example @CanuckCreator on YouTube where he does a teardown, revealing large holes.
This is not the way to go with toxic fumes or how to get good ABS printing performance.
Does it have to be sealed? Thinking of fume hoods which aren't but are ok. Can you link the vid?
Fume hoods have an exhaust to outside the inhabited area, which allows the interior of the hood to operate at a negative pressure. This means air is drawn in through the gaps rather than allowed to escape through them.
If this filter itself is effective, not saying it is, then gaps aren't necessarily a problem depending on where they are and if it still maintains the right pressure/airflow to the filter. Brought up a fume hood because if one of those had a filter for whatever was bad inside, and instead of exhausting outside it went through the filter, it would work still work despite the intentional gap.
I'm not saying the gaps are intentional or in the right place here, but that there could be an ok design with gaps. If you are exhausting through a filter you have to pull in air from somewhere.
A fume hood isn't at all comparable to what typically exist in the 3D printer world though.
He talks about it in this video: https://www.youtube.com/watch?v=HD__e064_U4
What's the timestamp? I can't tell from the part near the beginning if the holes that aren't on the part with the fan (presumably with filter in front of it?) sealed to it would be intaking or exhausting, and/or if some of them are for heat from the electronics but not contiguous with the build chamber.
