Description

Version 2 of HEPA and activate carbon filter (refillable)

Filter for closed Bambu Lab printers that combined HEPA and activated carbon (EAC- Extruded activated carbon). I have remix my old version improving:

increased capacity of carbon pellets (more than 30%).
improving slide fitting of parts
removed all print supports
ad a new “two finger remove” (better with two hands)
moved infill direction of grid for increase mechanical resistance.

Use a temperature resistant filament like ASA or ABS (maybe PETG), PLA only for first stage of testing (keep chamber temperature of printer under 40°C).

IMPORTANT: remember to adjust the shrinkage according to your ASA/ABS filament!!

bill of Material (amazon.it)

HEPA filter (same filter of bentobox, you can search hepa filter for robot iLife, V3, V3S, V3S Pro, V5, V5S, V5S Pro).
activated carbon pellets - (use only ACID-FREE activated carbon pellets), or use pellets of original Bambu Lab carbon filter.
cutter
if you prefer, strip for pull it out

assembling

cut the side excess of HEPA filter with a cutter
glue the strip (not necessary)
insert HEPA filter
insert activate carbon pellets (EAC)
insert slide cover on EAC
slide box EAC onto HEPA filter box
put filter inside printer
enjoy

considerations

New capacity of my design box for activate carbon is about 38g. Original Bambu Lab filter is 80g and it is guaranteed for 1440 hours (60 days).

So probably it will be necessary to change the activated carbon within 680 printing hours (28days).

tips

Set chamber fan at 50% of power in filament ASA/ABS start gcode with "M106 P3 S130" command.

Hello. Just got my first 3D printer (P1S) and with the lack of space/workshop room I had to resolve having my printer in my bedroom where I spend most of my days. I mainly have intention of just printing PLA PLA+ and PETG, but want to take the precautions I can. An outdoor exhaustion is a big no as well due to some complications with outside weather and such things. My main Idea was to have this filter and a BentoBox inside the printer as well. Should this help me with filtering out most of the dangerous stuff regarding my health? Thank you for your reply in advance.

Ventilation is still required, mainly to avoid health damage from volatile substances, and maintaining ventilation is the primary means.

@user_2651827137

Replying to @enixmeng :

Shouldnt these hepa filters get rid of the volatile substances? Best thing I can can do ventilation wise is to open the bedroom window for a few minutes after printing is done. Currently it is freezing temp outside so I cannot be opening it during the whole process. Thanks in advance for reply.

@enixmeng

Replying to @user_2651827137 :

A lot of volatile substances are generated in the nozzle heating process, many too late to filter out, after all, HEPA so small contact area, there is no negative pressure effect, you print will still have unpleasant odors, no matter how the negative pressure exhaust and air convection ventilation in order to be more effective to ensure health.

Printed perfectly. No problems at all. Comparison between original filter shown in photo. Hepa Filter fits in very snug and needs a quick trim. i really like this model.

waiting for hepa filters but very nice

@user_1458224682

I am unable to put back the slot cover. Is this normal?

The designer has replied

@riccardolisci

of course not. What material have you used?

@user_1458224682

Replying to @riccardolisci :

Basic PLA from Bambu

Parts fit together nicely, and it works perfectly in my P1P. Could use some kind of pull to help get it out of the compartment in the printer, but I'm not sure how that would be implemented. maybe I am just not doing something right that makes its a little difficult to get it back out of the printer. Either way, it servers the purpose, prints well and fits properly.

@riccardolisci

You can glue a small strip (see first version) or use two hands (with nails).

@user_1022400001

Please be aware to not use any activated carbon with acid in it, as it will start oxidating and rusting your printers. Do your research! If it doesn't specify acid free, then it probably isn't. Another consideration is that the stock chamber fan might not have enough static pressure to efficiently push through a HEPA filter.
