I Upgraded My CNC's Dust Collection With 3D Printed Parts... Now It REALLY Sucks!

In this video, I show you how I modified my wall mount dust collector with 3D printed parts for improved suction. I used the Prusa i3 MK3S+ 3D printer to create the parts for a dedicated dust collector for my Onefinity Journeyman CNC machine. Then I tested the suction and I will be sharing the results with you. I am sharing the 3D print files and links to purchase the wall mount dust collector, cyclone, So, get ready to see some real-life 3D printing, CNC routing and DIY dust collection ideas in action!

Stumbled on this video. Nothing to add but AWESOME ideas went into this!!!

[@UrbanShopWorks]

Thank you!

[@wowzande]

Look, I'm just gona flatout say it. I'm extremely jealous of you. I have had plans to do everything your doing, even the French cleat system on the wall but it's been a struggle trying to economically handle all of it and be able to put in time for these projects. All in all. Hats off to you, i had bought a canister filter for my harbor freight dust collector. Much better then the bag. You are on the right path. Like previous comments the reduction of airflow can still be reduced. There are alot of youtubers that go in depth of making a even greater system. I would even recommend having the vacuum motor close to the cnc spindle system and then connecting it to a main dust collection system. Being able to 3d print fittings, man. Your doing it and it's awesome that it's working out for you.

[@wowzande]

Also blast gates controlled by micro controllers. I mean you can go reaaaallllyyyy In depth with this making your place into a scientic lab/commercial manufacturing depo of sorts.

[@UrbanShopWorks]

Thank you! I don't think I need to get too crazy with adding more suction close to the spindle, from the cuts I have made the overall system works well in fact after 5 hours of cutting there was almost no dust that slipped through the dust boot and landed on the floor. This project has taken 5 months to get to this point between all the designing fabricating and problem solving and Im still not done!

[@UrbanShopWorks]

For my next trick Im need to make some sort of slide down table for the cnc since its not functioning the way I want hanging in that orientation on the wall.

[@l.rod2827]

Try reducing the diameter gradually to increase efficiency

[@MegaHinga]

Honestly your videos are really bloody good. Keep it up 👍

[@UrbanShopWorks]

Thank you, I appreciate it!

[@dpgedward5947]

thanks for the ride

[@UrbanShopWorks]

Any time!

[@saritsotangkur2438]

That router hood is designed for the high pressure low volume shopvac not a low pressure high volume dust collector. Use a 3 stage central vac motor instead of a dust collector. You can pair that with a dust deputy for shopvac so. Then use a similar spiral hose sized for shopvacs as well. Overall it will be cheaper smaller and easier use.

[@UrbanShopWorks]

Maybe that is the case but my system works and after having watched enough videos of other people using their cnc machines with varying dust collection systems and dust boots I will stick with what I have as it is more than adequate.

[@SunshineAndBass]

Quality content right here! Please post more :) Thanks

[@UrbanShopWorks]

Thank you!

[@MCsCreations]

Pretty interesting results indeed, dude! Fantastic work! 😃 But, honestly, even if the efficiency dropped by 50% it would still worth it. The bag is a nightmare! 😬 Anyway, stay safe there with your family! 🖖😊

[@UrbanShopWorks]

Thanks! Once I used it on some cuts I was pleasantly surprised at how good the dust collection was. The whole system works better than I had hoped!

[@cherowland]

This is so nerdy, I love it. 🤓

[@UrbanShopWorks]

Lol of course. Would you expect anything else from me?

[@glennwest267]

Love your work. Will do your stacked design. What about the mount for the ShopFox?

[@UrbanShopWorks]

I just made a simple box with a French cleat to hang it on the wall!

[@glennwest267]

@@UrbanShopWorks Do you have some alternative part numbers for 7" filters. Trying not to spend a fortune on the hepa filters.

[@UrbanShopWorks]

@@glennwest267 any should work as long as the diameter is the same, they are just standard shop vac filters

[@kuffyswoodwork]

I would definitely alter the dust boot to make better use of the 4" pipe.

[@UrbanShopWorks]

Now that I've had some time to test it I have to say it works surprisingly well even given the handy cap the reduction makes.

[@TheGrantAlexander]

Great data Preston! I would love to see the numbers after you have run a few cuts with the filters. Are the cylinders+cyclone that much better than the dirty bag? Only you can tell us!

[@UrbanShopWorks]

All that matters at this point is that the dust gets sucked up (which it does) and doesn't get blown all over the shop!

[@carlpetitt2241]

Interesting video, couple of items of constructive feedback: 1) I believe you're using those shop vac hepa filters the wrong way. That is, if you think about how a shop vac is designed, the suction source is INSIDE those filters and the dirty air hits those filters from the outside. In your design airflow is going in the opposite direction (inside out rather than outside in) to what those filters were designed for. No idea how much that impacts your results but I can guarantee it does impact it negatively. 2) You say you might look at designing a new dust shoe in the future. Well, you're right that it is far and away the largest factor in poor airflow in the system. You've got your new 3D printer now, I think this should be prioroity #1! You've invested in the cyclone, but that investment is wasted without a redesigned dust shoe that doesn't restrict airflow, and a different filter setup that uses filters for the airflow to go in the proper direction. My .02 cents. All the best!

[@UrbanShopWorks]

After a year of use I haven't made any changes to the dust collection system because it works. Yes the filters are designed to have air flow through the opposite way but dust doesn't escape them and the dust collection from the cut surface functions at an acceptable level. The dust shoe is the weakest link but after a year of use it actually works good enough.

[@killorkubed]

Jet (and others I'm sure) make dust collectors that have a massive scaled-up version of the sort of paper filter your using (they're a few hundred bucks but I think you spent near that on this filter setup...) anyway They have a handle on top that you can spin around and it runs something up against the inside of the filter to knock dust loose, It probably wouldn't be too hard to design a 90 degree angle pipe to go on the top of your filter stack that you could run a tube through, and then have some brushes or something attached to the tube to clean your filters, knocking everything into your filter trap, Id love to see another wind test with those filters plugged up after a few months of use

[@UrbanShopWorks]

I looked at all of that before I started this project, yes I could have just bought one of those filters but the fun for me is in designing and building this system and working through all of the problems as they come up. I know this approach isn't for everyone but this is where my current interest lies. The system I have made is very easy to clean ( I can literally stick the brush head of my shop vac into the filter stack) so there is no need to ever let it get clogged up, that being said obviously if it went several months without a cleaning and regular use I am certain it would lose a considerable amount of suction.

[@killorkubed]

@@UrbanShopWorks oh I totally understand the idea of designing and building everything lmao, I have nearly my entire shop in cad at this point... I just saw the jet system (I have a jet dust collector without that filter...) And always thought that cleaning solution was neat

[@UrbanShopWorks]

@@killorkubed oh it is, and I thought about trying to add something like that but this project has been taken months I believe I started designing in march and I only made my first cuts about 3 weeks ago. At this point I just wanted it to work, maybe down the road that’s something I may look at but there are a lot of other areas of my shop that now need some attention!😊

[@WPGinfo]

Thank you for the video. UNanswered: Q: How well does this collect DUST when cutting MDF & wood?? Isn't that the only IMPORTANT test / question to answer?? Please let us know!

[@UrbanShopWorks]

It works well, the worst I have had it is the first time I flattened the waste board and I took way too much off (probably 5 mm) and the dust started to static build up all over the outside of the dust boot and there was some dust escaping to the floor. all other cutting I have done that I would consider "normal" it keeps up to the dust load just fine.

[@WPGinfo]

@@UrbanShopWorks Thnx! That is good to hear! How does it compare to your previous system, both in 'result' & price??

[@UrbanShopWorks]

@@WPGinfo hard to compare as I have only used this system on my CNC and I have only used the other machine for the other tools in my shop. That being said My Laguna cost $2500.00 new and is a 1.5 hp where as this machine is significantly cheaper but is only a 1hp. This dust collector is only intended for the cnc and for that purpose it does the job. I feel like it would be ok for most of the other machines in my shop as well as long as the hose isn't too long. Also the footprint of the laguna is quite large and it takes up valuable floor space in my shop which I find annoying, this is another reason I designed this system to hang on the wall.

[@superphilschneider]

Thanks for a very good video. I wonder if you considered the fact that the 5 stacked HEPA filters are filtering in the reverse direction to their intended design. I think that the dust particles are normally supposed to land on the outside of the filter media and not the inside. Did you have any thoughts on this?

[@UrbanShopWorks]

I did not, however it doesn’t seem to be a problem. I have used this setup quite a bit now and the dust collection at the cutter head is more than adequate for the dust load. The filters appear to be functioning fine.

[@craigwickham7963]

Which filters are you using?

[@UrbanShopWorks]

The specific brand of filter I used is called Dura Vac its a filter designed to fit most wet/dry shop vacs from 5-16 Gallons. I got them at Canadian Tire, they are basically a generic 7 inch diameter filter you can find in any big box store.

[@ualdayan]

Did you design the CNC too or was it from a kit?

[@UrbanShopWorks]

The CNC is a Onefinity journeyman

[@deSloleye]

Is the flow enough to make the cyclone work? Not sure if that needs a minimum or maximum flow to work

[@UrbanShopWorks]

Yeah it actually work really well!

[@deSloleye]

@@UrbanShopWorks awesome! For one reason I think cyclone extractors and dust containment systems are super neat

[@UrbanShopWorks]

@@deSloleye Me too!

[@W4TRI]

About $70.00 in filters. How much Filament for the stack? I've been printing for 2 years now and I just want to make sure this is cost effective. PETG or better I'm guessing?

[@UrbanShopWorks]

The filters I used cost $50 each but I am sure they can be found much cheaper. For just the filter stack assembled I think about 2 rolls of 1kg filament. And yes I printed all of this in petg.

[@wowzande]

This is 138 bucks as of now, and it is stackable just like the 50 doller filters your buying. But much larger
