Thank you for the video and the files on thingyverse! I have printed everything in PLA (also the covers) which actually still works. The PLA is tougher but its still possible to bend it in order to fit it into the slots.
Great, thanks for sharing 👍
Hi Colin,
Thanks for sharing this.
Have you made any measurements on the amount of micro-particles and VOC's released with and without the filters ?
No i havent. But i would hope the hepa filter and carbon filter assist with particles and smell.
So I’m not sure about the vocs with the charcoal filters and whatnot but the hepa filters remove 99.7% of particles that pass through it, and while they have holes larger than 0.3 (nanometers or some other small measurement), micro-particles still get stuck inside due to clumping together along with the concept of Brownian motion.
Thanks for the great video! I hope to see more projects! Would there be a chance that you design an adapter for an exhaust hose?
The design could certainly be modified. Wouldnt need the filters. It really depends on the size of the hose being used (diameter)
@@colinhill Thanks for the answer! I would prefer the option to filter in winter and put the hose outside the Window in summer. for now i will use the original design. The filters are ordered and should arrive next week. the parts are already printed. thanks for the great design!
Are you selling these in a complete package yet. I would certainly would buy one .
Thanks.
Hi Colin, Great product!
Although it might add some noise, do you think mounting the fan on the exterior could avoid the turbulence problem? That way, any air being pulled out would not be directly hitting something that could create turbulence. Noctua Fans are pretty quiet as well, so it might not make a huge difference for noise.
I am also incredibly intrigued to see your addition of a temperature controlled system! I have recently been interested in finding a strong solution for maintaining a steady temperature for printing while also exhausting fumes/VOCs through an exhaust filter like you have created. Will you be basically adjusting the Noctua PWM based on a temperature reading to regulate the temperature inside? I have seen other ideas but they consist of turning on/off the fan, and in that case, the air might not be exhausted consistently.
Mounting the fan on the outside and filters on the inside would work as well. Its just you get the full sound of the fan, which is why i didnt do it that way. The temp controller is just a £15 humidity/temp unit from ebay, powered from 12v and has switching relays to turn off/on the fan at the required temps. I only use the Noctua speed controller for noise adjustment, so if i have to use Zoom or something for a call, i can turn the fan right down, then back to full afterwards. Its not essential. But the temp controller is a very cheap good solution, with a sensor on a lead included.
Hi Colin fantastic video thank you I’m thinking of making a enclosure for my elegoo Mars 2 pro resin printer due to the toxic fumes would this work on my wooden enclosure thanks
It sure would. You will just need longer M3 bolts to cater for the thickness of the wood you are using. You could bolt it to the top side, or on the roof of your enclosure, depending on clearance with the top of your printer. I do recommend the Noctua fan with fan controller thats mentioned.
Hi, very informative video, thanks for showing!
I have a small, cheap and fully enclosed printer, the creality cr200b. It comes with two 60mm case fans that are optional while running the printer. They are mainly meant to use as a heat control for high temp filaments. I wondered if I could use the extractor fan for filtering purposes through just popping an external filter-unit like the one u showed one there. Given i might need a stronger fan this could be an easy solution, or is there anything speaking against using the advantage of an existing extractor fan? Should the filter and fan size always match or might it make sense to even pop the 120mm filters on there?
Thanks for any response!
No reason why you cant use 120mm filters on a 60mm fan, as long as there are no places for air to escape. Or use smaller filters. Fan power may be an issue, perhaps get the filters, hold by the fan and see if you can feel air passing the other side of the filters. If not, try looking for a better fan. I use Noctua IPPC3000, plus another 'unbranded' make that is high pressure. Good luck.
Hi and thanks for sharing, I was looking for just such a thing. A question that I have not found an answer to.
If I have a fan that draws air from the case, does it take a fan that blows air into the case? If so, where should it be placed and what size? Thank you
So you want the extractor, and are also thinking of a fan to push air into the case. Unless your case is well sealed, this shouldnt be required. The extractor will suck air from around the door. You could possibly fit a small passive vent (low down on the opposite side). In my case i'm using a Tukkari TS enclosure for Prusa Mk3, this has 2-3mm gaps around the door, where the slot is for the filament to enter, and around the bottom edges of the enclosure. This gives plenty of incoming air that the fan will suck out.
Hi Colin. Nice project. I did that to my enclosure. I have one question. Can you feel air coming out of filterset? If I put hand to front of filterhouse I cannot feel that air is coming out of filterset.
Yes i can. If i hold a sheet of paper in front of the filter, it is pushed away. Did you use a strong fan? IPPC3000 recommended.
Hi, I generally like the design and am working on printing it for the enclosure I'm building at the moment
However, I'm having a lot of trouble printing the filter grills.
It is very difficult to get the first layer right with the crazy honecomb pattern. Furthermore the insane number of retractions on that pattern means my extruder is constantly moving over the same region of filament, almost flattening it entirely, which leads to it getting stuck in the bowden tube...
How did you get that to print successfully?
I'm currently using Prusaslicer on an Ender 3 v2.
slow down the first layer A LOT. There are a lot of retractions. You could always design a different grille yourself, like just a square hole format.
Great idea! And for how long this can work until you replace the cartrige? Any estimation?
No idea yet
Hi Colin, where exactly did you get your purifiers, the active carbon and HEPA
www.dream3d.co.uk/product/hepa-cover-filter-set/
What about air intake? Have you added any openings or is air sucked in through leaks in the cabinet?
If air could get into the cabinet easier, maybe the pressure wouldn't have to be as high and maybe a more silent fan could be used? Or would it produce to much draft? I do not own a 3d printer so I don't know how sensitive the printing is to drafts.
Abs is sensitive to draughts. The main issue is pushing air through the paper HEPA filter
Great vid. Do I need a specific type of 12v power adapter for this? The spec sheet for the noctua fan says max 3.6w and max 0.3a. Most 12 do powe supplies I’ve seen appear to be 1a minimum. Is this a problem?
No, the ratings you mention are draw power. A 12v 3A or 5A supply is fine. Or 1A if you have it. My psu often coonects to lights and other devices so the extra amps are needed.
Is there a extractor fan like this on sale on Amazon as I don’t have a printer for making the thingyverse yet
Ive not seen an extractor with the filters. I may be able to build one specifically for you if interested.
Where do you find the edpm seals? Your Printables page says 2.6mm width but I am not finding that anywhere. I'm in the US.
It was a long time ago. Just via Google i found a UK company that supplied EDPM. Or you could always print them from TPU?
Hi Colin, great video and very informative. However the hepa and carbon filters you use seem to not be available. Do you have the dimensions of the filter? I would like to have a go at making it however after searching for the filter I’m unable to find one at a reasonable price. They seem to have sold out on eBay so I will need to order from China most likely. Would appreciate it if you would let me know the dimensions of the filters used. Thanks you
I found them to be 119mm square
does the fan have to blow through the filters or can you set it up so that the fan sucks air through the filters so that there is no blowback ?
I need to redesign so the fan is on the outside, then it can suck. Watch this space, it s on my list to do soon.
I realize that you want it to be quiet, but would it not be more efficient to have the fan pull rather than push the air through the filters.
Not sure on efficiency, you may be right. I have moved the printer to a different room now, and that means i can indeed swap it all around and have a pull fan effect. Noise wont be an issue.
@@colinhill did you try to turn it around?
Sounds interesting!
Do you sell this kit in the U.K. on Etsy
Hi, i don't sell it as most people will print it themselves. However, i am looking at Etsy/Ebay and similar sites so will check this out over the next few days for anyone that wants a complete package.
