Great video! Just a general mask safety note.... In order for N95/KN95 masks to be effective, the perimeter of the mask must seal against skin. Having a beard does not permit a good seal and you will have bypass leakage. I recently retired from an industry where masks were sometimes required and I went through annual certification for using N100 masks. Others were certified for half face, full face or positive pressure masks. Facial hair was not permitted when wearing any of these masks. The air quality meter is an important tool to determine user risk level but most laser users do not have one. The best solution for lasers is to both filter and exhaust to outside. Not filtering may make unhappy neighbors if they are close by!
I have all my printers in my workshop, they are not connected to any extraction fans but when I print ABS I open the windows when I enter the room and leave the room for 10 minutes before removing the part, 3 of my 7 machines are in enclosures, after seeing this and another video on just how much VOC's are released even from PLA I will add air extraction to the enclosures and T into a room extractor and carbon filter, although the filter will not remove all the dangerous elements it is better than nothing.
Your local HVAC supply will have all those filters. Actually if your concerned about fumes and smoke in the air I would recommend speaking with a local HVAC expert. They are not only trained in heating and air conditioning but indoor air quality as well. Just speaking with a tech. on the phone could give you a lot of information.
I see your point as no air is being pull through the mask. Will think about a way to test further. Thanks for sharing. At the end of the day this is a difficult issue without directly venting outside.
can't you integrate the mont cap whose material filters well into the existing filter of the extraction? Then you don't have to wear a mouth cap at the laser cutting
@@MakeWithTech Any results? Instead of the smoke remover outlet I was thinking inline like where the tubing meets the enclosure or before going into the smoke remover.
Great video! I'm getting ready to start printing with ASA and am building an enclosure with a HEPA filter with a carbon element. I think I'll add a n95 respirator filter if I decide to vent into the house, if not I'll vent either through a nearby window or through the ceiling exhaust fan. I just got my first 3d printer in September an Ender3 V2 Neo after watching your video and I couldn't be happier! I only had 1 print failure and that was my fault I replaced the heat break with a bimetal heat break and they recommended using some cooking oil to season it when first using for PLA. I forgot I put the oiler on and the print came off the bed even with the glue stick then I saw the the oil residue on the bed. Problem solved! Thanks for making these videos!!!!!!!!
When I was printing PLA+ indoors after about 24 hours I was coughing badly it really impacted my throat. I bought a creality printer enclosure and designed a fan extractor and a 120mm fan with the goal of filtering it and potentially tubing it out the window but I never got a single successful print. The airflow itself in the enclosure caused the PLA not to attach to itself, I think it provided too much cooling air. I tried a variety of speeds and it was a nightmare to get it to adhere to the bed and itself. In the end I have put in an outhouse and I use an outdoor extension through a window to use it, which means it wont be very usable through the winter, but its better than destroying my lungs. Sounds like just filtering isn't enough, we need air extraction too.
Yes as I mentioned in the video printing PLA with and enclosure is difficult. Try putting an exhaust fan in a window in the room and then wearing a K95 or KN95 mask. The wait a couple of minutes to take off the mask.
What I do, and what I recommend to anyone who prints indoors, is to build an enclousure with a inline fan on the top that blows the toxins outside. By giving the enclouser negative pressure because you blow away the air in the enclouser, negative pressure is created and no toxic substances can escape into the hobby room and other rooms. I test it by placing a piece of paper against the door gap. If it sticks, you know that no toxic gases can escape. I am not in favor of just filtering the air as the filters have been tested in perfect conditions and with the correct flow rate and equipment, toxic gases will always not be filtered, especially if they are not replaced frequently. I also use an Airmega Coway air filter with Hepa filter in the living areas next to my hobby room for extra protection.
This video just came in time. So strange, I just got a 3d printer and ordered an enclosure for it since I don't want any crazy fuse from the prin out. My 3d printer is the snapmaker 3 in 1 so I plan on doing laser cuts. I wonder if my hako fume extractor would work any better that the one on your video?. I'll investigate and keep you posted. Fantastic video by the way. I plan to print near a window in my office so I might keep it more open during warm weather since winter is here.
I found your channel not too long ago, and i really love how you explain things, and your voice is really nice to listen to. thx for all the hard work. I know this is an old video, but i am looking into getting my first laser engraver something "cheap" like 10w maybe 20ish, and is now looking into this problem with smoke and fumes. i have alot of pc-fans all "silent" noctua 140mm and was hoping i could make something myself. I do have one thing i want to point out, and sorry if i am wrong, but i feel one problem in this setup you had in the video was that the enclosure was too airtight. You said you could see the window move in when the "Smoke Remover" was on, and that is a sign of air restriction, bad airflow. you need a good airflow for the bad fumes to get moved to the filters. again, i am a newbie, and i am most likely missing something here, but i do think i am a little right at least, its like breathing through a straw, not enough airflow.. i am sure you would get better results if the zipper wasnt all closed. Thx again for all your very helpful work, love the channel. - Michael 46, Denmark
I think you got a bad unit, the fan has a variable speed according to another review by Paw Paw's workshop. Thank you for all your work. I got a lot of great information from your 3D print videos as well.

There are air helmets for people with beard, i mean it exists not sure if employers provide those easily due to how expensive they are.

Putting the mask on the detector is the same as you would put a mask on a dead man.🤔😉 Guess why?

I was wondering the exact same thing
instead of wearing the facemask why not put the facemask over the outlet of the smoke remover?
Interesting idea. Not sure if the fan is powerful enough but I can try it.

Love the shirt!😊
It was quite expensive. 😀
Stay safe people dont cheap out on making your air clean.
Very good, it's getting to cold to go outside to work.
👍 👍
