3D Printed Modular Magnetic Exhaust!
HTML-код
- Опубликовано: 7 апр 2023
- I built a completely modular magnetic exhaust system for my 3d printer enclosures to vent the potentially toxic fumes 3d printing can release. I designed the system with future expandability in mind and to be able to be easily adapted to other tasks like soldering or working with adhesives.
In this video I am using an Ender 3 with an Ender Extender 400XL Kit. I've had the kit for over a year and love it! If you are looking to purchase one, I have affiliate links below, thank you.

You could use the fans in the original configuration. You don't need to get fresh air into the chamber so quickly, that will most likely mess with the temperature inside.
All you want is a slight negative pressure to make sure the fumes don't leak out.
Yea I definitely won't be running the inline fan at full speed, the computer fans were unable to get the fog out from the bottom of the enclosure, I think I would need to relocate the exhaust hole to the side in order to use them 🤔
@@LucasBuildsStuff or 3D print a column with small holes running top to bottom, to evenly pull air from all levels.
@@LucasBuildsStuff If you were to give your frames some feet. You could drill a few small holes around the outside edge as intake. This would provide a vertical movement of air and continue to mix the air inside before it is extracted. That would prevent pockets of fumes hanging out in the recesses. You could easily do the same flow check with a single hole in one corner and your taped paper to dial in a good hole size. I'm guessing depending on your interest you may want 4 to 9 holes depending on size and if you want one in the middle beneath the printer. I'm in the process of getting my first 3d printer but I don't have a dedicated room. It will need to be ventilated for sure.
@@LucasBuildsStuffYou need to create an intake on your enclosure.
To remove 25ft² of air you need to let 25ft² of air in.
hmm better to do it hermetic and after all run the fun before open the case.
Kudos for making this by yourself, I might get your files but I'm afraid my printer (resin) is too small to print those pieces. I also have an inline fan and I agree it's overkill but I also use it for an airbrush hut !
What's your max print dimensions?
wow this is a well done implementation. I'm looking for ideas for mine and it has really inspired me
Thank you, hope yours works out great!
Super sick! Glad I found your channel 🤙
Haha thanks again!
Great video, has given my some ideas for a modular extraction system for my airbrush spray booth 👍
Thank you! 😃
There's also an easy way to get 12V without a buck converter. On aliexpress there are USB-C to 12V adapter cables, which simply tell a USB-C charger to deliver the wanted voltage. They are available with a lot of different voltages.
Ompp.pl😊
incense is decent to use for airflow
I'll definitely keep that in mind for next time, thanks!
The magnets are a great idea.
Thanks!
Awsome design! This video was really helpful in gaining some foundational level understanding on enclosures and filtration and is helping me out coming up with my own ideas.
i was a little confused on why your original system didn't work when you were talking about the CFM. Why was did the 3rd fan slow down your system? Wouldn't the individual fans still take out 46 CFM regardless? Wouldn't the 3rd fan increase the CFM more? I am not too sure how this works so I would like to get some clarification.
Thanks for watching!
When combining 2 pipes into 1 pipe, the total CFM of the 1 equals the total CFM of the 2. In the video the Y-pipe had equal diameter inputs and outputs, which means in order to increase the CFM of the output the speed of the air moving needs to double. Having a 3rd identical fan choked the speed and therefore reduced the CFM
So cool! I'm going to try this! 🤩Just out of curiosity, what was your reason for making your own and not using the ones 'Once in a Six Side' made?
Was it just to have the ability to expand on the design, or were there any flaws in his quick connect design that you corrected with your own? 🙂
Thanks! No flaws that stood out to me, just had different requirements like the Y pipe, computer fans and I had a bunch of the smaller magnets in stock 🙂
Wait I’m confused, isn’t resin printing the one that gives off toxins and fumes? The only time I’ve seen people have filament and filament printers in inclosed cases is so they can run them with a dehumidifier since filament is less efficient in humidity.
Besides that I really like your design! I was looking for some diy options for resin!
Most plastic release some levels of toxic fumes when melted, the levels for PLA and PETG are considered low enough to be "safe"
Thank you! 😃
@@LucasBuildsStuff gotcha!
I was cringing at your original 3, then 2 PC fan setup. But you figured it out with the last fan downstream of the Y. Main takeaway is more is not always equal to more (your 2 46.5 CFM fans, for example, would not produce 90+ CFM at the join regardless).
The link for the 'Ender Extender Kit' is broken
I believe they are changing business' and discontinued the affiliate program, you'll need to google them to get the most up to date link. Thanks for watching!
I want to build this, but instead of inline fan, can i use double 90cfm 120mm case fans? (i don't know the pressure they create)
It would depend on your enclosure size and how far you need to push the exhaust.
In a perfect world 90cfm would exhaust a 3' x 3' x 3' enclosure in 20 seconds, and stacking 2 case fans should push the air a few feet. Thanks for watching!
@@LucasBuildsStuff Thanks! i got the files last night, will give it a try with 120x38mm fans
Thank you! Hope it works great! 🤞
Do you have the stl files?
Hey! Yes, they are linked in the description, thanks for watching!
I really want to find wire strippers like that 2:26
B&Q seems to have some, they're called "Self Adjusting", "Auto", or "Ratcheting" Wire Strippers. Thanks for watching! 😃
Went from a $10 cpu fan to a $100 blower. Missed the mark by 10x.
An effective $100.00 blower beats the hell out of damaging your lungs.
@@JohnDoe-zx1ck he should have gone with something more in the $20-30 range. no need for a 100 inline fan let alone 2 haha
i mean.. why not buy a fourth PC fan when you already bought three.
did he say kaknurled lol
😅
I breath lead.
