Description

We can increase the Carbon filter size in our printer and we didn't know it!

Here is how to increment your carbon filter up to 161% of the original package filter, or up to 123% by adding a Hepa filter!!!

I opened the original Bambulab Carbon Filter and weighed the carbon: it was 63g. I read online that there's supposed to be more, but this is what I had, and on the official website it only shows the Package Weight.

Bottom box: Carbon filter

I managed to fit a maximum of 45g of carbon, even if I suggest using around 42g to avoid carbons obstructing the sliders, it might be a problem when the box is inside the chamber slot, and you insert the top box.

You can try to keep shaking the box to fit more carbon.

Watch the video below.

Top box Option 1: Hepa filter

I managed to fit a maximum of 32g of carbon, I suggest using around 28g.

Cut the side excess of the Hepa filter, with scissors or a cutter, and push it inside.

Same rule here, keep shaking the box to fit even more carbon, but make sure the filter doesn't rise above the edges, or it could get stuck when you need to get it out.

Easy access to the filter so you can take it out easily.

Total Carbon filter of 77g!!!

Print the first plate Carbon & Hepa

Top box Option 2: even more Carbon filter

I managed to fit a maximum of 56g of carbon.

Again: shake the box to try fitting even more carbon!

Total Carbon filter of 101g!!!

Print the second plate Carbon

Bill of Materials:

Original Bambu Activated Carbon Air Filter (or get any activated carbon filter you like)
Hepa Filter (Hepa filter for robot iLife, V3, V3S, V3S Pro, V5, V5S, V5S Pro)

I printed it using PETG material and so far I haven't had any issues with it, but I'm a newbie and use only PLA and PETG filaments for my prints, so feel free to use ASA or ABS if you think it's the best, and adjust the shrinkage according to your ASA/ABS filament if needed.

Extra Handle:

I've designed a simple handle that you can use to pull out the top box from the printer' slot,

but it's not necessary as you can easily use the original cover as shown in the video below.

Additional Profile: Customizable Grid

I've added a second profile that allows you to customize the grid size directly in the slicer. Feel free to adjust the grid size to suit your needs, but be cautious not to make it too thick, as this could obstruct the printer's airflow.

Printing instructions:

I've uploaded two profiles, choose the one that best suits your needs:

Carbon & Hepa Filters
This is the original version, designed for use with the standard Bambu Lab Carbon Filter.
Carbon & Hepa Filters - Customisable Grid
Select this profile if you want to customise the box grid.

Each profile has four plates, but you only need to print one:

Carbon & Hepa (Option 1)
Original size for Carbon and Hepa boxes.
Carbon (Option 2)
Original size for double Carbon boxes.
Carbon & Hepa - 0.5mm less deep (Option 1 - Adjusted)
Same as Option 1, but 0.5mm shallower to help with slot door clearance. If you've had trouble closing the slot door, or want to prevent this issue, choose this version.
Carbon - 0.5mm less deep (Option 2 - Adjusted)
Same as Option 2, but 0.5mm shallower.

Easy to print with PETG and excellent results I preferred purchasing carbon sheets (AMAZON, ASIN: B097B4SH55), I find it simpler than pellets One box slides smoothly into another, with the lid included Thank you very much for your work

Thank you for the boost and sharing the picture!

@GarciaJohn

Hi. Is there any concern about the acid-washed carbon material being used in your carbon sheets? It is heard that acid-washed filter would damage the matel part inside the printer. Any good suggestion? Thanks.

@user_4111473750

Replying to @GarciaJohn :

Thanks for the warning, but I have no idea about your concern. This filter is in Amazon Spain, with ASIN: B097B4SH55. I can only suppose that if it doesn’t (should not) damage the hardware is designed to filter, our printer should be safe.

this is really good idea but my printer now sucks air from the rear chamber fan insted of blowing why is that. no air flow?

The designer has replied

@Tribio

What?? it's not possible the fan is supposed to blow air outside!! can you try removing the filter with the fan on and see if the issue is the filter? do you use the HEPA filter? if so, is it the one I suggested?

@AlexP1s

Replying to @Tribio :

yes i used everything you used. i removed both filters and it blows strong and with it starts sucking and weak

Works good! I hope to see how it handles printing with ABS soon, many thanks!

@Tribio

let me know too! I only print petg and pla.

@MartyMcflyUk

I printed this with ABS without any modifications. just do it.

@TheSylencer

Replying to @Tribio :

So I printed it out of PLA, and after 30 hours of printing ABS there's no warping or melting on the carbon holder. Works very well.

This is an excellent model with a clever idea to add to the storage. I printed this as well in a well tuned PETG. The slot for the hepa filter and lid fit very loose to me. I would be concerned about the lid to remove the bottom box falling out and dumping carbon. They might benefit from a little nipple or slightly tighter fit since petg is also often slightly underextruded for quality. I'll probably put a dob of silicone or similar. I also agree with others that the mesh on the bottom of the carbon is large enough to potentially leak carbon. I plan to put a very thin breathable foam of some type on top of it to keep carbon out. I'd suggest the same for others to prevent carbon dust from coating your machine and space. I might try and wrap the foam as well on the sides to gasket seal and secure this from vibrating. Of all the carbon and filter designs around though this is the most clever and best looking setup. Once my filters arrive I can give it a proper test. I hope it works as good as it looks!

@Tribio

Thanks a lot for the boost and the feedback! You are not the first to say that the lid is loose, I printed it in PETG and PLA and I didn't have any problems, but I'm a hobbist, so I can't guarantee this of course, maybe there is something I don't know! I had similar problem with another model of mine, I have really no idea, I'm sorry! About the bottom, I'm thinking to add a new model so that the size of the grid can be updated in the slicer! Thanks again for the feedback!

@tastyratz

Replying to @Tribio :

Oh no apology needed this is a killer model! I just had ideas. A little positive bump nipple/rib on the lid with matching negative on the model might make it more likely to snap in and be secure with more flow/fit variability tolerance. If I was reprinting the model I might have manipulated the scale slightly for petg to compensate (but I'm lazy and hate waste). Something like this is what I was thinking for under the carbon cut to fithttps://www.aliexpress.us/item/3256806275880654.html

@Tribio

Replying to @tastyratz :

No worries at all, your feedback is actually very helpful! Same concerns have been pointed up from other users as well. Maybe I'll add a "bump" to secure a bit the lid. The bottom filter would be wise!

This is an ingenious idea! congrats for coming up with this idea. I’m excited to be able to add more filtration capabilities, better safe than sorry, especially without long-term study on health due to plastic printing! Few small feedback (printed in PETG): 1. lid and box are loose fitting, easy to slip and spill when moving around 2. original filter cover cannot close properly on right side, box seems to be blocking latch (depth of new box larger than original)

@pandabears

Boosted

cont’d from above 2. (cont’d) maybe small indent on right corner to allow clearance for latch on filter cover 3. there’s a cutout on bottom left corner of top box; would have a cleaner look if closed up like the bottom right corner Since my P1S is new, I was really eager to use this new model while I await more carbon pellets to arrive; seems I got lucky since original Bambu filter had enough to fill first box and have additional for second!

@Tribio

Thanks for the feedback, other user had the same issues, I'll improve the model in the next month or so. Thanks again!

@torsoreaper

Worked out really well. Used Fusion 360 to make the base of the charcoal holder its own body then used the no top or bottom layers trick to just have grid infill as the filter. This worked out perfectly for charcoal granules that aren't even pelletized.

The designer has replied

@Tribio

Nice! Yes, that's something I'm planning to do next! So that the grid size can be updated in the slicer.

Everything came out perfectly. It was very easy to place into my X1C. The fitment is perfect. Great job on the design!

@Tribio

Thanks!

@MyTechGuyRI

Even MORE filtering efficiency.... Stop using the activated carbon granules... Buy cut to fit carbon air filter pad... the carbon pad has even more surface area for more efficient removal of contaminants than the granules. https://a.co/d/eWQBoiH

@user_806808912

so, cut the carbon filter pad into sheets to fit and layer it?

@MyTechGuyRI

Replying to @user_806808912 :

yup

@MB450S

Very nice design. Fits perfectly except that in my case the door does not click quite right. I do not know yet what the cause is. This is the third design that I have tried now and so far definitely the best. Thank you!

The designer has replied

@Tribio

Thanks for the boost! You're not the first to experience this issue. I've made another profile with boxes that are 0.5mm shallower, but I want to print it before releasing. I should be able to print it tomorrow!

Replying to @Tribio :

If you want, I would like to be notified when you have uploaded it. Then I can print it again... As I said, this is the best I could find. It fits super tight, not rattling loose.

printed with ABS. After first miserable fail (bed adhession failed completely), made a little modifications. changed build plate to Engineering one, added mouse ears to all corners. this helped and came out flawlessly. ABS is still very tricky to me and somehow I just can't get it work on textured PEI plate.

@Tribio

Thanks for the tip and the boost! I'm sorry but I can't help much with ABS material 😞
