I am currently building a vent system that circulate the air through a HEPA filter and only let air out of the enclosure if it is getting too hot. The flow of the system is controlled by a small RPI hat and is connected to an air quality monitor. I wanted to use the RPI cause I already have one for Octoprint, but it would probably have been better to just run the ventilation off a Arduino. One thing that I am really careful about is draft inside the enclosure. I will let PPM values get a little high during prints rather than circulating too hard. Instead I will circulate and vent once the prints are done. I like your designs and also found Onshape a very valuable tool for these projects. Keep up the good work. Cheers.
I'm not expert in this but HEPA seems useless for the 3D printer fumes. HEPA is good for removing particles down to 0.3 microns. But those are usually dust, bacteria etc. Fumes molecules are way smaller (from 0.001 to 0.10 microns) so they would just fly through the HEPA with ease. I will be checking if the prints get any worse because of the draft but so far it's been printing great. Since I print with the printer door and top closed I believe the draft won't be strong enough to cause any issues
@@therealfazee That is actually not correct. It is true that HEPA filters list their rating and effectiveness for 0.3 micron particles, but that is because those "medium-sized" (medium as far ultra fine particles goes) are the hardest to be catched by use of a filter. A bit counter intuitive, but both larger AND smaller than 0.3 micron particles will get stuck in the filter easier than the 0.3 micron ones will.
thank you for uploading this i felt like i went through each step and revision with you. i appreciate the time you took in documenting your journey and fleshing out the video. i’m thankful you saw it as a learning opportunity because i certainly learned something too.
thankfully it's a covered patio, but it could still be helpful to a little sloped ledge above the top of the outlet, to reduce the risk of water ingress. (and also caulk the outer part's flange to the door). also, maybe a very thin layer of some squishy silicone rubber or foam on the interface between the vent and the printer, to prevent leakage. because the fan is inside the printer, the adapter where you connect the hose is at a positive pressure, meaning any gaps will leak exhaust back out into the room
What are the cons of adding an inlet fan to the exhaust pipe? I still get plenty of VOC's (smells) coming out from the top/front. Venting the main exhaust and auxiliary exhaust on the other side a bad idea? The air flow that would be sucked in would come from the poop opening. I was thinking could add a small heater chamber that can heat the air being sucked in to control temp to keep the chamber at desired temp and maintain a good airflow that takes all the harmful air out and away.
I imagine you want just enough flow to keep a negative pressure on the print enclosure, especially when printing materials that require a heated enclosure. I also plan on building an exhaust to keep nasty fumes out of my home but high flow is not needed.
I use what is basically a grow tent, vent hose has an inline fan which I feed into a big cylindrical carbon filter which is way overkill for the small enclosure but works a treat. Search “grow tent carbon filter” to see what I’m talking about. I also run an air purifier with carbon filter in the room for when I’m not using the enclosure, like with PLA and PETG.
inline fan is in the plan for Ventilation 2.0.. :) tent is a good idea, even with ventilation on the smell still gets out of the printer through all of these small gaps etc..
@@therealfazee No smell gets out due to the pressure differential. When I turn the fan on to its lowest setting the sides of the enclosure are pulled in, even with gaps in the zipper for power (printer and lighting) and Teflon tubing for external spool or AMS. I use the enclosure for resin printing too and never smelled a hint of anything even with resin that is definitely not low odor. Of course I eventually have to open the enclosure eventually, that’s when I kick the air purifier to high. I’ve also covered the HVAC intake on that floor. I live in a 3 story townhouse; printing stuff is on the mostly-unused first floor (laundry, garage, front door). My setup isn’t as good as just venting straight outside but it’s the best I could do and honestly works better than I’d hoped.
One thing I have learned is that using threads to connect 3d prints is usually better than magnets. Unless you really need to connect and disconnect the item often.
yea I kinda need to disconnect it from time to time.. but yes the 3 magnets I used aren't strong enough to hold it, next version will hold itself by being snug tight and magnets just securing it
the draft going out will make your bed vary in actual temprature as its not a circulated heated enviroment pulling in cold air that will cause cold pockets idside the build area and your alignments out of tollerances like the cold pockets shrink and the hotter areas expand you get a pretzel
maybe having the hole further from the door handle would be better... especially when its a door you need to lock from the inside! great work and thanks for the ideas
it doesn't really matter in my case as the door leads to balcony and it's never locked, but I see what you mean.. if it was door to public spaces I would rather use window insert vent
I'm not really that proficient in Onshape. I watched thread tutorial on YT and making it was basically trial/error process haha. I believe those tutorials will describe it better than I ever would.
The exhaust system should be weak enough that it shouldn’t pull air from across the room. It should be no stronger than the HVAC system pulling air for recirculation.
You've got to remove the carbon filter and remove the little the door to it for proper ventilation. I've tested air flow, and the "Temperature control" fan actually sucks air inside the enclosure in the stock and unmodified X1C
Are you sure about that? Because when I put the chamber fan to 100% I can definitely feel and smell the air coming out of the housing that I placed outside, it's not sucking the air from there, and my X1C is stock. To remove the little door might be good idea though, will probably do that when the filter is due for replacement
@@therealfazee I've tested the air flow using a piece of toilet paper and to my surprise the piece stuck to the back of the fan instead of being blown by it, so it's definitely sucking air in. After some research, I found a thread on the subject on the Bambulab forum (search for "P1S: Chamber Fan Direction"). Incredibly, it explains both your result and mine. I think there is not enough air flowing from the enclosure to the fan, so the path of least resistance involves taking air from outside the enclosure and immediately blowing it outside. Surely this can be improved upon
@@therealfazee the net air flow is going outwards, but I think that there is too little air from the enclosure getting to the fan, so the vast majority of the air is sucked in from outside and immediately blown back out through turbulence. I can't find out if this is by design... I have yet to create a venting solution of my own. I'm still in the process of printing parts, so let me know if you end up testing opening the little door to the activated carbon while printing ABS or PC. I'm not sure it's a good idea to vent with an increased flow of air since these materials need high temperatures to flow correctly and prevent warping, and it might be hard for the X1C to keep up with an increased flow. However, I would tend to at least try to increase the air flow because I hear the X1C fogs up with VOC (deposits?) when printing with ABS.
@@eliotbolduc1672 that's true it's not much of air even at 100% as the fan is more like PC fan for cooling rather than extracting it out. That's why I was thinking on adding the extractor fan in the line. But the room definitely doesn't smell when I print PLA (70% aux, 70% chamber) and I can smell it when I get outside so must be working to some extent :) haven't printed ABS yet I but I realize the high airflow might cause warping or lifting issue, will see. Yes X1C fogs up pretty easy even when printing PLA or PETG (the glass was all fogged up not sure which one of those caused it lol). Thanks for input!
@@eliotbolduc1672 I am currently looking into designing a similar system for my BL X1-C, by venting straight out to an open window, via a 75 mm felxi-duct magnetically attached to the printer. I would only really need it for printing ABS, ASA or similar type filaments with toxic VOS gases and odorous emissions. I learned that if you leave the stock carbon filter in place and conduct an airflow test on the chamber exhaust fan, it actually appears to suck in air and release very little by way of output. however, if you remove the carbon filter it is a different ball game and it now becomes a fully fledged extract fan. I am not sure what effect that simple move alone would have on chamber temperature stability, but I image that thermistors report chamber temperatures to the controller and then it engages the fan only as required for chamber cooling. Exhaust of VOCs is a secondary consideration as it is an enclosed printing area. My design will include a 75 mm (3") flexi-duct hose direct from a 3D-printed reducer flange magnetically connected to the rear panel of the printer over the exhaust grille. The other end of this hose will have an 80x80 mm 12v fan attached, wired through a PWM motor speed controller. Using this controller, I can ensure that it doesn't overspeed and negatively over-pressure and pull too much air out of the chamber. I want it to run with just enough speed to keep a slow and steady movement towards the exit end of the duct. As there is a potentiometer on the controller, I can dial in the optimal settings after experimentation. Maybe someone has already done this and can save me lot of time? Many variables, lots of reasons to fail.
I note that where the fan is on the printer the wall in front of it looks like it's metal, is the side of the Carbon X1 Magnetic Metal, Aluminium or plastic? Have you also thought about increasing the magnetic strength by fitting a shim between the fan and the internal wall of the printer with some slim n52 bar magnets in it? this would mean all that you would need for the out side on your connector would be a thin metal plate.
The rear panel of the X1-C is steel (ferrous metal), so yes it will respond well to using magnets. The sides however are aluminium alloy and will not react to magnets.
potentially dumb question: is venting REQUIRED for the X1C? I'm planning on getting one but It would have to be in my room. (Noise isn't a factor to me, im not worried about the smell either) but I'm trying to find information on if it's actually required. I'm thinking about getting this one over the P1P because I heard it's print quality is overall better than the P1P. Thanks in advance!!!
Print quality can be the same if you calibrate your filament which is generally easier with the X1C which can do it automatically thanks to the lidar. However auto calibration doesn’t work with sparkly or translucent filament. I only print in an enclosure when I’m printing ASA or PC, but I also run an air purifier in the room with a carbon filter because printing with any filament gives off VOCs.
the nerve.. :D will be making a V2.0 soon, will be designing all the parts from scratch instead of using someone else's work, and will release the STL's
Hi friend, your project looks really good. Congratulations. Wouldn't it be worth using an extra fan? Are you using the printer's own fan? Friend, I don't know how to make 3D objects. Can you please share the project files? Thank you very much in advance. 
Yes I'm only using the printer fan. I guess it would be ok to add an inline fan, planning it for V2 if I ever get to make it (together with relay on the valve so I don't have to open it manually)
im about halfway through the video, and i think you will have an airflow problem. a single computer fan wont be adequate for the application. Ill watch the rest and find out if that ends up being a problem edit: looks like u ended up going with a larger diameter pipe. nice
thanks. From what I tested the small fan has to run at least at 70% to be able to push. I already bought inline fan to solve this, coming in V2.0 :) Also the temperature differences might be important. Seems that during colder weather it's easier to push the air from the printer outside. During summer (Florida) it seem to linger around the printer door and smell more.
the hose is connected with magnets, the hose will just detach and flop to the floor. it's also magneted to the back of the printer, so it's unclear which end will detach first, but that doesn't matter here since either way, you just... stick it back on and everything's fine.
