Just finished printing custom vent pieces and got it all in place. Now I can print stench free.
Why didn’t I think of using a printed green buttcheek to navigate my waste air out of the room. facepalm I’m doing it all wrong!
😂 Exactly. This is the way. Who would have thought you use a butt to help remove stinky air from the room!?!?
I mean, a butt removes stinky air from our bodies, so the logic is there.
Just copy nature, every time
That’s why I ate my wife after she dumped her eggs on my coral reef
The lingo kids use these days...
TIL: I probably need ductwork for my butt.
Do you have a fan on the other side to avoid negative pressure within the tubing?
I'm not sure what you mean. I have a fan and booster fan pulling air to the outside.
Isn't that linux 😁... You got my attention now 😅
Yes. Pop station.
Only thing is auto repair doesn't work on Linux.
What do you mean by pop station? Music station 😁 I used linux before, its tricky to get everything working on it. I use a lot of adobe apps and back in the day they were laggy, slow, crashing randomly and i just give up and switched back to windows.
I would like to have some kind of linux server at home, maybe video surveillance system. Currently all that is on win machines
Sorry I meant pop_OS Linux.
Thanks. Does the otherside just vent outside or do you have a fan attached to it?
Yes. I have a booster fan half way and then another inline fan a few feet before the window and it vents out that way. I haven't made any custom parts for the window yet. So it just vents to the screen and I have some foam blocking it off. Does the trick.
Can we see the booster fan? I did this same thing but it seems my booster fan is a bit lacking.
Is that a... VHS collection?
Damn right.
All children’s movies too.
Let's just hope that's the correct copy of Holes.
Thanks! Is that just a 2" inline fan?
3 inch inline converts to 4 inch at the booster.
I do something similar and I don’t need any additional fan.
Awesome! I thought about doing that, but I like to keep the chamber warm, so I decided against it. I just put the machine in a grow tent and connect the exhaus hoset to the tent. It's not a pretty setup, lol.
This is the way. Especially for ASA
I find even PLA smells and triggers my asthma. So it's a must for me. Even the carbon filters I find don't do a whole ton. However I like to believe I'm capturing some toxins and preventing them from going out into the air.
I'm just super sensitive all of a sudden. Many years ago.
Not sure if it's the same for you, but I had a sensitivity to Elegoo PLA but had no problem with Bambu or Polymaker PLA. Not sure what the difference is but the smell of the Elegoo was noticeable and made me a little lightheaded and the other brands were undetectable by me. Either way, you have it covered with your setup, so that should take care of anything!
Yeah I've been getting lightheaded too and using Elegoo. I'm not sure it's a problem now that I can vent it all out like that. May be a coincidence however as I've been having health issues before having my 3d printer related to being dizzy/lightheaded. So I couldn't say one way or another. I do know any plastic fumes seems to trighmger the tight chest feeling that's for sure.
Fair enough. I like this way because it's cleaned and it honestly so far doesn't seem to reduce the temps that much. The fans are not super strong. Only a 3 inch inline fan and a 4 inch booster fan. They're quite low wattage.
I used an ender tent lmao. It works so well though.
Can you check how hot it gets inside the grow tent (not in the printer)? The electronics in the back are exposed to heat
I have not own one yet, but I am going to and put it in my bedroom.
Seeing this post got me curious how bad is the smoke to the point you made a custom vent for it? Are you printing anything else beside PLA and PETG?
It’s not smoke but vocs and ufps. It depends on what you print, each vendor has their own recipes. Some PLAs and PETGs can stink while others don’t but are likely still not healthy. ABS/ASA are definitely harmful. PC may be depending on the blend and if there is bpa or abs/asa mixed in.
I wouldn't put it in your bedroom. I have it in my office and for any print thats longer than an hour or two it stinks up the room. I usually leave the door closed, air purifier on max, and window open.
Going to do some kind of setup with a grow tent in the future (and vent that out).
Man, that is too bad. I do not have any other available space that not either directly to sunlight or dry 24/7. What do you think if I make a vent just like OP from the printer to outside via window? would that be enough and possible to keep it in my bedroom near my PC?
Cant just get blinds on the sunlight location?
Yeah I mean venting it can work but also its pretty loud with lots of LED's I wouldn't be able to sleep next to it if it was printing haha.
Yes I can get blind or make things to cover that is not what I worry about. The heat surrounding the printer that what I worry about. I read it causes a clog in the nozzle.
The loudness I can work around it I used to have a PC running 24/7 with fan 100% training ml, I can sleep through it with earplug lol. But smell gonna give me migraine. I am more smell sensitive than sound.
Yeah don't sleep with one running in a bedroom, especially if it's not being vented properly.
Oh no I will install a bunch of sensors for safety as well due to space constraint, if possible I love to have it even make a custom vent like you.
I did something similar for.my resin printers. Nylon and pla+ doesn't really smell tho lol you mainly printing abs or something?
Pla does smell and it triggers my breathing issues. It doesn't when vented.
Oh I never noticed. Btw I'm not knocking the vent. I made one myself. Even modeled the y connection etc.
Yeah fair enough. Even if it doesn't smell. It's for sure letting off toxic voc's to some degree. More so with the hotter plastics of course.
Nice dude, congrats
Thanks! Appreciate it.
How much/what do you print to need 2 of them. I got one and it's damn fast.
Do you still find a ton of air leakage? I find even if all fans turned off and everything closed that the room smells of ABS/ASA and need to leave it empty for large prints.
Do you just leave the chamber fan on all times or something?
I don't believe there would be any leakage. The smell goes from noticable to literally no smell. The fans are just strong enough to keep a negative pressure in the enclosures. When I open the doors to remove a print I can hear the air going to the back.
I'm not sure about chamber fan settings. I just assumed when you printed something they kick on?
I had this issue too, I ended up purchasing a 4x4x8 grow tent, and put my printer inside that. Then used an 8” inline fan at the top to exhaust all the air from the tent and vent outside through a window
Yeah that's what I'm going to do I think. For long prints I basically I cant be in the same room which is annoying haha.
How strong is your fan? Have you turned the fan on, and checked air velocity where it exhausts out to?
The 3 inch inline fan is a 25w 118 CFM
The 4 inch booster is 13w 95 CFM
I have no way of checking the exhaust velocity. I'm sure it's not a whole lot. But it sure does eliminate the smell.
I only ask because thats a long hose, and wasnt sure what fans you had. There's usually some design criteria you can look up to get an idea of what duct velocity should be, to ensure contaminants (VOC's/fumes etc) get transported all the way through and exhausted out.
I was just curious, thats all. I hope I didnt come off as rude.
Theres some equations, you can do but you need at least some rudimentary air measurements. Honestly, what I would do if you dont have anything to read air velocity, detach the first duct from the second fan and turn on the fan at the printer, and dangle a piece of paper (or tissue or something) over the duct opening to visually indicate it is flowing well. Then hook it back up, and do the same check at the exhaust ourside with everything going.
You can also, use a smoke tube, or incense or something to create some smoke at the inlet of the fan in the printer, and first see how strongly it draws, then second you can again detach the duct from the second fan, and use the smoke again and check to see if the smoke is making it all tye way to the second fan.
What I'm explaining are great qualitative checks, without needing actual numbers or measuring devices.
Let me know if that helps.
I'll give the smoke test a shot and see.
I did similar and added a high flow exhaust fan with speed control! It’s the best for anything beyond petg heat range.
Got any closer photos of the back or the overall set up? Id like todo the same at my place but need some direction.
