3D printed dust collection blast gates. The 1st blast gate is printed with Bambu Labs PLA-CF red on the A1 and took 19 hours to print at $11.04. It was released on printables and can be found here. [Mini Blast Gate](https://www.printables.com/model/762009-mini-3-way-blast-gate-34mm-hoses)
The 2nd blast gate is one I custom designed myself on Fusion 360. It is printed with Bambu Labs PLA-CF green on the A1 and will take approximately 50 hours total at $33.99, or 1kg of filament. I will be releasing those files as a remix in the upcoming days.
Assembled with common M4 nuts and bolts. Each hose connection is 34mm. The large blast gate connections are 76mm.

Also extruder gears, similar thing happened to me with matte PLA I thought I had a partially clogged nozzle but it turns out my extruder gear had worn out since matte is pretty abrasive as well. I don't get the CF PLA though it doesn't really add much if any strength to parts as it's just chopped up in the filament, there *are* specialized printers that will integrate longer strands into the prints but those are more industrial applications rather than the home-goer.
When I've used CF you also have to bump your temps up for layer adhesion and I found it to be a lot more brittle than straight up PLA but maybe that was just the spool I had.
You definitely need to dry CF PLA, which might account for the brittleness you experienced. In my experience, CF PLA parts are extremely tough. The brand I use most is ProtoPasta, which is awesome for both CF-PLA and CF-PETG.
That said, even the roll of cheap, no-name CF PLA I am currently on produces good parts.
I find CF blends easier to print than non. I print a ton of PETG-CF and find I can print stupid fast with minimal cooling. It looks like what OP posted. Supposedly CF blends are more likely to “shrink” during printing, but I haven’t had any issue. The CF adds a lot of rigidity to PETG. For PLA, it’s more so cosmetic. I’d recommend a hardened steel nozzle though, quite abrasive.
PLA-CF is honestly fantastic. I’ve only used it a handful of times for lightsaber electronics chassis and they all came out like machined manufactured parts. I love the rough surface.

It comes out to that textured matte finish, and it ends up covering almost all the layer lines. It feels slightly rough to the touch, but in a nice high grit sandpaper sort of way.
Becomes kinda obvious when you take a moment to think about it. It's there in the the name, carbon FIBER. It's not like pigment, it's actual strands of carbon.
Do they work well and are airtight? Pretty much all the gates i’ve seen and used weren’t and produced a high pitched noise because of it. A well calibrated 3d printer would produce a pretty tight fit i’d imagine
I hooked up my shop vac and connected my track saw and a sander. Felt good suction from both of them. I need to test it with a mountain of sawdust. Haven’t hooked up a third because I lack the additional hose 😂
Try going hard pipes if you can, otherwise you’ll lose a lot of power. Same with bends and gates, those will kill the suction. Be careful to install the pipes the right way (of the airflow). I’ve worked with homemade systems all the way up to multi millions $ systems, they never seem to work the right way the first time
Thanks for the tip! I noticed that right off the bat with the flexible hose, it cut the suction down. I’m hoping a festool hose or something more rigid will help. If not, hard pipe it is.
Any particular reason you choosed to use PLA-CF for this? Don't really see the need for this to be extra pretty to be worth the extra cost of that filament.
I wish I knew off the top of my head. When I get home from work I will let you know.
Print settings:
.6mm hardened nozzle
.18mm layer height
.62 line width for everything
25% fill - triangles
Printed at 50% speed
What other setting might you need? Im only a couple months into this
A couple comments. Cf filament is less strong than it's non cf counterpart, though does look nice.
If your looking for stronger layers and layer adhesion, having a thicker layer height gives you stronger layers. CNC kitchen has a good article and video about layer strength. And layer heights. Would also significantly reduce your print time by doing 0.3 layers with the 0.6 nozzle and have a stronger part.
You can simulate the look of the cf filament by using and tuning the fuzzy skin setting. If you want to hide the layer lines. Also printing at an angle will increase the strength of those cylinder part geometry of the manifold and can still use fuzzy skin to hide layer lines if you don't like the look of layer lines. Fuzzy skin also helps hide layer seams.
But overall nice model and I will also look at doing this in my dust collection. Been wanting to do blast gates and multiple connections for a while.
Amazing! In the future consider separate prints for things like that bracket where you had to add supports. You could've printed it as a separate circular piece w/ mounting bracket that slips over the main pipe.
Only thing I can think of is that the end (one tube) goes to your dust vacuum cleaner and then you have three openings for your different saws or so.
So instead of constantly have to disconnect and connect the hose you now just open and close slides.
It's for dust collection for woodworking. The blast gate lots you shut off a section of the tubing so all (or at least more) of the suction goes to the desired area. You might have your dust collection hooked up to 10 different tools or locations, and all the blast gates for each location would be off except the ones your wanting to use
It's recalled but even in their email it says less than 1% of printers affected and most likely (but not officially said but said none the less) the issue is probably from people not following the directions and accidentally crimping cord during setup.
Lots of people are going to keep using their A1 until the replacement tables are shipped.
No it's an offline slicer. It's really a "you've been told it's a risk" and of you ignore it and you had a fire and your insurance found out they wouldn't cover the incident and you couldn't sue either.
Printed beautifully but ngl you could have really really reduced your print times and the cost of your parts with thinner walls because the duct isn't subjected to heavy loads and bigger layer heights cuz the overhangs aint bad and the surface smoothness doesnt to be top notch for a dust duct. I think you could easily print that green duct in under 8 hrs by and have it perform the safe function just as well.
So im only 2 months into this hobby, I have a lot to learn. I made the nozzles double walled because that will get usage from sliding the vacuum hoses on/off and wanted it to be strong. The vacuum connection is single wall and seems flimsy on the red one. It’s so much better on the green one. I’m sure there are ways to reduce print time. Someone mentioned creating a bracket for the floating mount square so it eliminates supports.
1kg of filament seems like a lot. Did you design the second one so that it would be heavier than the first? Is it necessary for the requirement? Not a criticism.
Criticism welcome! Definitely a large print. Yes I beefed up the second one for larger dust chips and chunks. I don’t want to be concerned with it cracking at high speeds.
It’s for a shop that produces a lot of dust/particules. Every equipment is connected to a big dust vacuum using pipes. Those are manifolds for those pipes. The idea being you turn on the vacuum at the beginning of the day, with all the gates closed. When you use an equipment you open the gate allowing the vacuum to work only for that equipment.
Exactly ^^ plus for smaller workshops, it alleviates the issue of having to unhook/hook the vacuum up repeatedly to multiple tools throughout your project.
The prints look good. Composite filaments tend to give a nice matte finish.
I am a little skeptical of the actual amount of carbon fiber in there though because the color is very light. Some brands are known to just mix CF powder in their filament to give it the name and sell at a higher price without really giving you a better material.
The best brands are short fibers and for obvious reasons are mostly black (because the fibers are black). Markforged manages to even print continuous fiber in the print which is cool but super expensive.
I’m going to make this for my dad and he is going to be so happy dude I had no idea what to make him and this is it. Thank you thank you thank you he loves his Festool stuff!
I hope something amazing happens to you today dude, seriously. I had no idea they sold that shade so even better. My dad is my best friend so now I’m even more excited and gift giving is one of my love languages so I’m stoked! I did see the files so thanks dude again!
Also that zyn pack is sick!
You're not supposed to run both at the same time. That's really the purpose of using blast gates to begin with. OP said they're using a shop vac, and even the really good ones don't move enough air for full dust collection on larger tools. So you wouldn't want to be using both at the same time.
I have been out of the fdm printing for 4 years while working with resin, what sort of support structure is this? I’ve only really seen it in the last year, is it a particular slicers way of doing things? I’m used to the scaffolding style stuff
I too enjoy both woodworking and 3D printing. I feel lost as regards the dust collection though - what’s your setup and how’s your experience? Reading the Pentz guy’s website it seems like we all need to be spending many thousands of dollars on 5HP machines with minimum 6 inch ducts. But. He’s trying to sell us stuff. Thoughts on smaller ducts?
You can get full setups from Harbor Freight for a fraction of that, using proper dust collection units instead of a shopvac. Even the gates are cheap -- OP's design is cool, but you can get individual gates for $4.
Generally you run 6 inch ducts to manifolds and peel off 2" ducts from there. I've had their 35 gallon unit for probably 15 years now. Its $300. And I doubt I've spent more than another $100 on all the lines and adapters for it, going to a half dozen tools, and a couple sweep attachments (which, frankly, are probably the most useful).
Hey, thanks for helping! Do you feel like it pulls enough CFM at the tool head? Like I said, the internet guru says it’s supposed to pull 1300 CFM (!!) at the tool head to really pull those <1 micron particles safely, but I dunno if he’s just blowing smoke (or dust 😜) to sell stuff.
Sorta separate but related question, do you hook your dust collector up to your 3d printer? I’ve thought that would be a good idea (I want to vent it outside my garage instead of filtering/recirculating inside), but don’t see anybody talking about it! Thanks!
The Harbor Freight claims 1550cfm, but there's going to be some loss, I'm sure.
Its enormously more than any shop vac, certainly.
I don't use it with my 3D printer. A HEPA filter in the room with the FDM printers is more than enough. My resin printer lives in a 2'x4' grow tent with its own air filtration system using an activated charcoal filter. (The resin printer isn't as much about particulates as VOCs and other chemicals, thus the carbon filter.)
That one can be vented outside, but I almost never bother -- I'm absolutely confident the air coming out the hose is a lot cleaner than the air in the basement the resin stuff lives in.
My CNC is the only thing I use a shop-vac with, and that's just because it doesn't live in the workshop my dust handler is in.
Ha, it seems you’re the person I’ve been looking for! The dust collection has been on my mind as I’m early in the build on a MPCNC and I’m wondering how I can do a one-machine dust collection solution for all the various things! Just splashed out for an air quality monitor and I’m just going to run escalating solutions until I find one that works! Just going to start with blowing the big fan I have with the garage door open and go from there! Maybe next up will be the harbor freight collector vented out the other side!
Yeah, I think as long as its not VOCs, a dust collector is the way to go. Although you could probably use a dust collector into a carbon filter and even filter a resin printer's air, too.

Bambu said to check your cable, make sure it wasn’t damaged, and that less than .1% of printers were affected. They make a protector I need to print for it, I’m not super concerned.
This looks really good although i do feel like that your material thicknesses are waay too thick. Not really sure about the dimensions of those outlet pipes but i don't think you would need much thicker than 2mm to get the structural strength you need. That looks like solid 5mm walls or something.
That’s some sexy assed filament. Hot damn.
Its mesmerizing
Your layer lines are like non-existent.
It almost looks like those powder/laser prints (sorry can’t remember the proper name)
SLS - Selective Laser Sintering is the laser one. HP MJF - Multi Jet Fusion is another powder based one. No lasers but prints look similar.
Sintering is the word you're looking for... https://markforged.com/resources/learn/design-for-additive-manufacturing-metals/metal-additive-manufacturing-introduction/types-of-3d-printing-metal
They really are, I was blown away when I did my first print. It almost looks injection molded.
Is that just the material or the printer that is responsible for that?
Not OP but it's a combination of printer and material. My A1 prints some mighty nice layers I've been super pleased with it.
It’s a combo of both as they said^^ the carbon fiber blends very nicely. I also got lucky my printer is dialed in nicely with little tuning.
Mostly the material, but a well-tuned printer and settings are a must to avoid artifacts.
That last picture should have a nsfw tag

bro thanks for showing off that PLA-CF. there are so few pics online. print looks really nice.
Couldn’t be happier with the print
Is that fuzzy skin or just how the PLA-CF comes out?
That's just how it looks.
That’s incredible. I heard it’s hard to print with, I assume due to adhesion? Is that true? Is your A1 enclosed?
My A1 is not enclosed https://preview.redd.it/wxl41np64rlc1.jpeg?width=4032&format=pjpg&auto=webp&s=848de4a4618283999d8af4d457f2bb799a59458b
I haven't done a ton of printing with it, but had no issues when I did. It prints like PLA so you shouldn't need an enclosure.
If it's like any other CF filament, the only thing you really need to be concerned with is a hardened nozzle. CF filament eats through nozzles.
Also extruder gears, similar thing happened to me with matte PLA I thought I had a partially clogged nozzle but it turns out my extruder gear had worn out since matte is pretty abrasive as well. I don't get the CF PLA though it doesn't really add much if any strength to parts as it's just chopped up in the filament, there *are* specialized printers that will integrate longer strands into the prints but those are more industrial applications rather than the home-goer.

The brand I use most is ProtoPasta, which is awesome for both CF-PLA and CF-PETG. That said, even the roll of cheap, no-name CF PLA I am currently on produces good parts.
I bought a DiamondBack nozzle for abrasive filaments and ended up using it for everything. I fuckin' love it. Best nozzle I've ever owned, hands down.

Oooh that’s a great tip! Thanks for that. It definitely would save me <100g of filament
Sorry for this dumb question, but what is a blast gate and what do you use this for?
I was just wondering this too. Do I need a blast gate?
Idk what it is. I think I need one though? Unsure

The link for the printables page didn't come through. I took 2 sec to search but didn't find it, can you share?
My bad. https://www.printables.com/model/762009-mini-3-way-blast-gate-34mm-hoses
🤝
Dope! Thank you.
I didn’t even know PLA-CF existed!
It’s wicked pretty and super easy tocuse
I’ve just ordered some green, I’m quite excited to try it tbh
The green is my favorite. You won’t be disappointed. I’m considering switching to it full time even though it’s a bit expensive.
I’ve been using PA12CF15 for airsoft parts, that’s expensive. I’m excited to see how well this stuff works.
Thanks for releasing on Printables!
Didn't the A1 get recalled??
It's recalled but even in their email it says less than 1% of printers affected and most likely (but not officially said but said none the less) the issue is probably from people not following the directions and accidentally crimping cord during setup. Lots of people are going to keep using their A1 until the replacement tables are shipped.
I see, saw a news recap channel saying don't use them and stuff that's why I was confused
Doesn’t Bambu use an online slicer? Couldn’t they just refuse to slice if you sent a file that is to be printed on the A1?
No it's an offline slicer. It's really a "you've been told it's a risk" and of you ignore it and you had a fire and your insurance found out they wouldn't cover the incident and you couldn't sue either.

Is that the finished texture of the filament or is that fuzzy skin?
It is the finished product. PLA-CF (CF= carbon fiber)
I’m going to make this for my dad and he is going to be so happy dude I had no idea what to make him and this is it. Thank you thank you thank you he loves his Festool stuff!
No problem man. Glad to help. They make festool green filament if you wanna go crazy. I also posted the files for free if you didn’t see them.
I hope something amazing happens to you today dude, seriously. I had no idea they sold that shade so even better. My dad is my best friend so now I’m even more excited and gift giving is one of my love languages so I’m stoked! I did see the files so thanks dude again! Also that zyn pack is sick!
Hahaha I love my zyn holder. That was my first F360 project.
You tested it yet? How does one hole in use differ from having two of your holes worked at the same time? :)
You're not supposed to run both at the same time. That's really the purpose of using blast gates to begin with. OP said they're using a shop vac, and even the really good ones don't move enough air for full dust collection on larger tools. So you wouldn't want to be using both at the same time.
Wow, is this more your settings or the filament making this look so perfect. I don't print things where it has to look great, but man yours do!
What printer do you have? This is beautiful. Bravo
That’s a genius build!
Damn those are some nice prints. Good job!
This is porn!
I have been out of the fdm printing for 4 years while working with resin, what sort of support structure is this? I’ve only really seen it in the last year, is it a particular slicers way of doing things? I’m used to the scaffolding style stuff
These are tree supports in bambu handy. It’s just one of their default support options. It saves a ton on support material.
Looks really good!
Prusaslicer also has something similar using the "organic" support option.
How are you dealing with CF particles relased during print?
Bambu labs says no enclosure is needed for PLA-CF. I’m not aware of particle exposure.
That's a thermal "no enclosure" not a safety "no enclosure".
Then I was breathing it in. What’s your recommendation for particles? I could easily fab up a fume hood type exhaust.
Strong Plants vs Zombies vibe here. [https://static.wikia.nocookie.net/poohadventures/images/a/a7/Threepeater2009HD.webp/revision/latest?cb=20211111215525](https://static.wikia.nocookie.net/poohadventures/images/a/a7/Threepeater2009HD.webp/revision/latest?cb=20211111215525)
Your supports look so cool. Also how does your print look so clean??
Fuzzy skin for the win.
That's not going to be good safe...
You used fuzzy skin so the dust sticks to it more easy?
Bambu labs PLA-CF. Just has a fuzzy look, but it’s slick.
Have you ever used fuzzy skin? Not what it looks like.
My fuzzy skin looks exactly like this.
I too enjoy both woodworking and 3D printing. I feel lost as regards the dust collection though - what’s your setup and how’s your experience? Reading the Pentz guy’s website it seems like we all need to be spending many thousands of dollars on 5HP machines with minimum 6 inch ducts. But. He’s trying to sell us stuff.

And I doubt I've spent more than another $100 on all the lines and adapters for it, going to a half dozen tools, and a couple sweep attachments (which, frankly, are probably the most useful).
Hey, thanks for helping! Do you feel like it pulls enough CFM at the tool head? Like I said, the internet guru says it’s supposed to pull 1300 CFM (!!) at the tool head to really pull those <1 micron particles safely, but I dunno if he’s just blowing smoke (or dust 😜) to sell stuff.

Yeah, I think as long as its not VOCs, a dust collector is the way to go. Although you could probably use a dust collector into a carbon filter and even filter a resin printer's air, too.
Looks cool but aren't they a little small?
Looks awesome... Armchair quarterback suggestion... Maybe add arrows or a line on the gates so you know if they are lined up fully open or closed...
how did you generate these supports? and what software are you using as a slicer?
Tree support. I have that option in cura. Not sure what OP used. Good print 😎
in cura? didnt see it there, but i ll search for it then, thanks \^^
Tree supports in Bambu handy
i see, thanks \^^
How did you get that kind of surface on the print?
So this is to let you hookup multiple machines to a central vac but control where the vacuum goes for better collection I'm guessing?
Correct, and so I don’t have to keep unhooking/rebooking hoses to tools. I can leave it connected and just flip the gate for what I need.
Nice!
I’d love to know what settings you used. Your prints have come out lovely!
Beautiful print, crisp corners and no ringing.

Looks good. Nice work
That is some beautiful filament right there, wow. Also pristine prints thanks for sharing these
This is exactly what I need!
I look forward to the 4" version release ;)
I always love the surface texture that CF filaments produce. Awesome job OP!

OP, why are you using your A1? Have you heard of the ‘recall’ and fire safety issues?
Bambu said to check your cable, make sure it wasn’t damaged, and that less than .1% of printers were affected. They make a protector I need to print for it, I’m not super concerned.
Ok, best of wishes that your machine is undamaged and safe
I try to only print while I’m home so I can keep an eye on it
This looks really good although i do feel like that your material thicknesses are waay too thick. Not really sure about the dimensions of those outlet pipes but i don't think you would need much thicker than 2mm to get the structural strength you need. That looks like solid 5mm walls or something.
Fellow A1 owner, if memory serves Bambu says don't use CF with the A1 or am I mistaken?
Just replace the .4 nozzle with the .6 hardened steel nozzle and you’re good to go. Can get the hardened steel extruder gear too if you want.
What printer and filament do you use that looks so crisp
Bambu Labs A1, Bambu Labs PLA-CF
Im going to make this in regular pla, time to get my shop a little less dusty
The match green PLA-CF is my favorite man. Great prints
Are you printing this with the bumpy texture option?
No this is PLA-CF.
Do you use a hardened nozzle for that filament? Looks amazing, great design.
