Man, I can't believe that a so important and useful video has only 200 likes. People should pay more attention to these risks. Thanks a lot Nathan for such an accessible summary of the topic, really nice job man!

So far, the most informative video in the shortest span of time I've seen 'researching' the topic. No weird claims or attempts to upsell, just facts.

Great video, started printing recently and my girlfriend got a migraine 2 days in a row while printing, but i was fine. I dont think im stupid but i didnt think about fumes and nano particles from printing plastic. Using 3 of those cheap indoor fans till i finish cleaning out our spare room to close off the printers from the rest of the house. Aside from that with the extra ventilation she hasn’t had migraines.

Thank you so much for making this video. I'm getting into resin 3D printing and have been trying to learn before buying a printer. This has been a huge help!

Thanks for a great video! My 3D printer work area is an old desk, I built a box on top using plywood and plexiglass, and connected a 4” duct to create negative pressure around the hood and blow the air outside through a standard clothes dryer vent. I also mounted a smoke detector in there. The stinkiest filament I’m aware of is fire-resistant ABS, I can print that and not smell a thing.

This video is so well detailed and yet nicely concise. This is so valuable, thank you for sharing this information in such a great format!

More people need to be aware of the safety risks involved. Thank you so much for sharing.

I knew it. As soon as I thought about plastic and heat, I knew we are going to have issues. I would also assume that vaporizing these materials would cause microscopic particles to be in your space, on your floors, walls, etc, which means they will get kicked up into the air when vacuuming or even walking around, sitting down on floor, having a child who plays on the floor. Removing particles from the air using a HEPA filter is not enough. If tested, areas where 3d printing is happening are probably going to show particles on surfaces regardless of a HEPA filter in the room. Just a disaster. The only way to do this is to have a printer be isolated in a shed inside an enclosure. But it's all just not worth it. I wonder if printer materials also leave microscopic particles on your hands when you handle them...ie, the printing process probably leaves microscopic particles on surface and I'm not sure if due to the abrasive nature of a print, if particles aren't coming off the objected when handled later.

I was literally just thinking about this because I recently set up my printer next to my desk in a small office. I feel like everything from a cursory Google search just says PLA is safe so this breakdown is very important

Havent purchased my 3D Printer yet but I am planning on using Nylon G for Professional use, so I'm doing a ton of research into this ahead of time. So far, I am going to get an enclosure to put the Printer in, use a filament heater to keep the filament in while it's feedinng during Print time, then have a carbon filter next to the Printer in the enclosure along with running a tubular air duct from the enclosure to a HEPA filter then directly vented outside. Might seem a bit much but there's no way in hell I am going to work with Nylon G and not take protections against the possibility of glass particulates floating around my house. Better safe than sorry.

I have recently been looking into HEPA filters for a DIY airbrush spray booth. I would also be using this spray booth for post-processing 3D printed models. This info came in really handy right now. Thanks for the tips!

If I throw my HEPA room air purifier circulator next to my printer, do you think this would be a good solution in a space I can’t vent easily?

I've been looking into adding HEPA or MERV filtration to my P1S. I'm considering anything between simply adding a sheet of MERV fabric on top of the built-in carbon filter, a HEPA filter so the exhaust fan, to a bento box v2 in the enclosure. Do you think any of these or a combination of these would be enough to keep the air in my office pretty clean? Or would you still advise getting some kind of standalone air filter?

Thanks for the great video! Looks like I need a HEPA filter!

Good video...HEPA is a pretty simple thing to implement so well worth doing, apparently!

I was thinking of getting a 3d printer for myself but it wouldn't be in a very well ventilated room. I think I'll hold off until I can be in a space that is well ventilated. :/

Hi I'm a newbie in the 3d Printing world and I really thank you for speaking about the printing hazards in this vid. I'm getting my first FDM printer, I plan on having my printer in my room (due to some limitations) within an enclosure (a box on my shelf) with an extractor fan leading to outside, I know it isn't the fanciest set-up but, would it work for making a safer work enviroment and battling the plastic fumes? I know this video has some time but I'd apprecciate if you gave me your opinion on this! 🙇‍♂️

in case anyone hasn't noticed its dangerous to your mental health as well. but seriously, good vid. subbed i could see the air in my office when the sun shines in the window in the afternoon when i'm printing so i went ahead and bought a carbon/hepa cylindrical cartridge that was on sale for cheap ( walmart :( .....) ... but it was $12 and the actual unit its supposed to go in is 80. it might actually be the same brand. just printed a disk with a hole in it to strap a pc fan to and leave it running... then put the smoke detector and the little filter thing into my own version of a lack enclosure (made from creform tubing)

Just get a enclosed with bento box?

Will a Bambu lab a1 mini be fine in my bedroom open , with a hepa and activated charcoal purifier right next to it ?

Thank You!

Have you done this for resin printing?

Hmmm hepa filter with activated carbon can’t stay long time in store or etc before you buy

Hey I just recieved a creality ender v2 3d printer and I live in an apartment with not much ventilation. I was wondering if I buy a HEPA filter and put it next to my printer will it filter out the toxins that you metnioned? Would I have to take extra steps like putting a cardboard box over it with the filter inside and opening the wincows after a print? I just don't have many options because it's a small apartment and the windows aren't close to the printer.

I grew up in the mean decades of the 80s and 90s where smoking was everywhere, 70s boat cars where everywhere as well as their fumes, and not to mention the lovely high VOCs of paint lingering in our walls a we moved from place to place. I'm 39 and still kicking... Thank God. I'll crack open the window, set my air purifier on sleep and let the 3d run. Truth is, Pollen can kick ones butt FAR worse than PLA, which is what I use only (at 200 degrees).

I just sold my Resin printer because I was worried about the health risk with resin and now I see this. I wanted to by an FDM printer instead. Would you say that this is still safer than working with resin?

Always the same scenario. First a person wants to scary people and then sell them a cure for it!! Hahahaha.

Thanks for this, I was looking for some papers to confirm the theories about HEPA + Activated Carbon. Do you know of a good air sensor to test the effectiveness of our filter solutions?

Thank you for the informative video! I have a question regarding the use of an enclosure for my 3D printer. If I buy an enclosure and place it in my room, will the VOCs still be a problem, as they may condense within the enclosure? Alternatively, I'm considering placing the 3D printer with the enclosure on my balcony. Would this be a better option for mitigating VOC-related concerns? Any advice would be greatly appreciated!

Super vidéo really all the information I need thank you

한국에서도 암 발생 논란이 많습니다. 좋은 영상입니다. 일단, hepa 필터만으로도 어느정도 문제 해결 가능한 것이군요.

is PLA toxic? can i have my ender 3 in my room and don't worry about it if i only use PLA?

I've always been told having a 3d printer in your room printing PLA is safe. idk why it took me so long to look into it

Long haired good looking young tech Jesus, please give me a good idea beside the Levoit system (which I already use). I need something small to put inside my 55x55cm 3D printer enclosure. I want to keep the air inside circulating which will filter it even better while slower over time and recycle the heat inside. The enclosure is basically a cabinet. Somebody a good idea ? I go have some 120mm case fans sittings around and I wanted to use the HEPA14 + activated carbon filters used in cars, soldering stations, kitchen etc. just not sure which one to choose, it was ha so be small and flat.

Hello, very interesting lecture, could you tell me if the hepa filter catches VOCs? Does the VOC remove the carbon filter?

Hello, I just got my ender-3 V2 3D printer and am planning on using Pla for printing. I am probably gonna place it in my room. Do you think I am gonna need an enclosure to be extra safe?

Would you recommend something like this when using a 3d pen?

well I think I am done 3D printing

Is that purifier in your link good enough? it says it can only handle down to .3 micron, which according to the study from Korea isn't quite good enough. Please correct me if I am wrong.

Excellent video. Thanks for posting!

Great video and a usually completely overlooked topic. I wonder how high the VOC levels get for all those folks printing with resin printers in living areas. Anyway, thanks!

Would using n95 or kn95 facemask help?

Wasn't there a study done that showed that the nano particles are basically not a threat due to how minimal it is? These particles were only able to be detected within hours of printing in a small enclosure and that they were barely detectable even then.

If i am printing just PLA do i need a hepa filters?

One of the ugly things about particles in the .1 to 1.5 nm range is that they tend to lodge in your lungs. Smaller particles act like a gas and get exhaled. Larger particles can land on cilia in your lungs and get swept up and out. Particles in the middle where HEPA is not as effective are the really dangerous ones.

Can't i just print outside? Would be a lot easier xD

It is true health and safety laws govern this in the workplace so if you use a 3d printer do not use in a room with no ventilation and it should be in a airtight cabinet and vented outside through a filter if you use one at home these particles and or fumes are bad for anyone in the house just wearing a mask is not enough

Ummm..I have never had my printer above 202 degrees.

Nylon release no toxic VOC's why speak nonsense? See video for all plastic danger "Всё о филаментах для 3D печати - характеристики, печать, применяемость"

Am i going to die😭

Replace the china crap psu with an atx one designed for computers(NOT FROM GIGABYTE) and a boost converter. you'll make the printer actually UP to code and it will have a very low chance of catching fire.

Don't care
