Do You need Air Ducts or Exhaust for Your 3d Printers?

A 3d print farm can fill the air with fumes, odors, and particulates. Here is a few ways to clean and move some air out of the room.

This video deserves much more attention. I see alot of people running even print farms that don't concider any ventilation setup which feels a bit bad.

[@bluelightning0820]

Great information, had to watch on 2x speed.

[@djdubd]

I like your setup, it is similar to what I had in my head to setup in my printing room. I would need to use a window as well for exhaust and appreciate you not only doing the leg work but putting it all up here in an easy to digest format! I have a question though, will the window exhaust fan suck out too much air and affect print temperatures? I know that the P1S and X1 have active systems to compensate for this, and you seem to print with higher temp materials a lot, has the addition of the exhaust fan affected your prints due to more air circulating through the printing chamber?

[@WaynesForge]

No, the P1S and X1C do Not have active heated chambers. But the X1E does

[@Jestey6]

@@WaynesForgeMaybe, but the bed and nozzle are heated and during printing the temperature in the cabinet does go up. In fact the Bambu printers in this video switch in fans to control the temperature. It appears that there is a lot more going on than you are aware of.

[@imagebuff]

Same question as above. Does sucking the air directly from the enclosure affect your chamber temps and therefore somewhat defeat the purpose of the enclosure? Have you tested the effect of the exhaust fan on chamber temps?

[@Ggoodnight35]

Have you tried printing ASA with this set up? I have very similar (Bento Box, Duct work with inline fan) and i can’t print ASA because you can’t run chamber fan and not having the print warp.

[@PlasticPusher]

your confusing exhaust fan with the aux cooling fan you dont run the aux fan with asa but can still use the exhaust fan with no ill effects

[@brianatencio8342]

Newbie here but question about the setup. The Makereorkd file is for a 3” hose snd the blower is for 4” hose. Do I need to modify the print file, or do you have a 4” adapter to match all the other products you linked?

[@nobeam]

Amazing thank you for making this

[@Eng.AntonioPerez]

User If you attach an inline fan to the enclosure and extract this air to the window, will the draft and air movement in the enclosure affect the prints?

[@gsdtdeaux7]

Only issue is if you ventilation pulls to much it will pull all the heat out of the enclosure and cause crappy prints. It needs to match the stock airflow just piped outside. And the door has a big ass crack in it so like others have said just as long as theres negative pressure thats whats important

[@ashleyspianoprogress1341]

I printed the exhaust fan adapter but do I need to get a blower or is having the exhaust pipe connected straight to my P1S and out the window good enough? I only have 1 printer.

[@MrDanDizz]

The key is negative pressure, that more air gets pushed out from the enclosure than in so that minimal particles escape the enclosure and instead out of the exhaust duct.

[@johndowns4161]

will the adapter fit the p1s bambu as well?

[@MarineTrucker1775]

I’m looking at buying the bamboo lab x1c do I need to do all this if I’m only using PLA-CF?

[@gsdtdeaux7]

No

[@xxjegamingxx7833]

By any chance do you have the link to buy the magnets?

[@johndowns4161]

Yeah I am finding the .50 but most are thick 0.12 maybe he meant .12 instead of .10 on the printables page

[@Jestey6]

The objective, the venting of fumes generated by 3D printers outside is laudable. However, the video portrays a lack of understanding of basic principles, it is tedious, omits important information, and has not been thought through. Both the Bambu P1S and XC1 have auxiliary fans which vent fumes from the enclosure, they also have activated charcoal filters to absorb VOCs, if ducting to outside is employed, the filters can be removed. The internal auxiliary fan is controlled by the on board electronic circuitry, which monitors the enclosure temperature, and adjusts it to ensure good quality results, when using different filaments. Using 3” ducting and a sizeable blower will almost certainly have a negative effect on the quality of the of the printed items. All of the printers, in the video, are connected permanently to the blower, there are no gates to select the printer in use. If you have all your printers running 24hrs a day, this might be ok. What is required, to remove fumes from a printer is, a printed magnetic connector, 2” duct, and an external vent cover. If such a system fails to provide sufficient air flow, due to duct length , a “small” fan can be added. If multiple printers are being used, then a means of connecting individual printers using gates and a means of controlling volume would be required.

[@nicholasfrasco2947]

I can see how that would work. Thanks

[@johndowns4161]

Get a variable speed exhaust like infinity and you can create negative pressure slightly without venting too much. I try to buy variable speed on anything I buy.

[@Jestey6]

@@johndowns4161 Hi John. I can see where you’re coming from. Perhaps something like the Amazon EpheyFIF Quiet Inline Duct Fan with Variable Speed Controller for £11:39. However the printers, P1S and XC1 already have an auxiliary fan which exhausts the fumes via an activated charcoal filter, into the room. This fan is variable speed, and has sufficient power to force the air through the filter. If the air is ducted outside the filter can be removed, this improves air flow. This is the set up I have, and it works fine. My P1S has its back to an external wall, as a result the duct length only needs to be about 15”, and the system works well, using 2” flexible duct. Outside I fitted a three flap cover, and there is sufficient air flow to slightly open the flaps, which is sufficient, and doesn’t affect the internal temperature of the printer. If the duct length needed to be longer, an additional variable speed fan would probably be necessary. Cheers Noel
