CPAP Muffler dB and Air Flow Test - Mammoth-3D: Comprehensive Analysis
Mammoth-3D CPAP Muffler: Reducing Noise by 13 dB with 100% Airflow for 3D Printing Part Cooling
The Mammoth-3D CPAP Muffler is specifically designed to reduce the noise generated by the cooling fan (24V Brushless Centrifugal Air Blower DC WS7040) in 3D printers, while ensuring that the airflow required for effective part cooling is not compromised. Here’s how the muffler achieves a noise reduction of 13 dB and maintains 100% airflow:
Noise Reduction Mechanism
1. Sound Absorption Materials:
The muffler incorporates advanced sound-absorbing materials that dampen the noise produced by the part cooling fan (Air Blower). These materials absorb sound waves rather than reflecting them, significantly reducing the overall noise level.
2. Acoustic Design:
The design of the muffler includes internal baffles or chambers specifically configured to disrupt and attenuate sound waves. This sophisticated acoustic design helps in reducing noise without impeding the airflow needed for cooling.
3. Precision Engineering:
The precision afforded by 3D printing technology allows for the creation of intricate internal structures within the muffler. These complex geometries optimize noise reduction by creating pathways that minimize sound transmission, effectively lowering the noise by 13 dB.
Maintaining 100% Airflow
1. Aerodynamic Pathways:
The muffler is designed with aerodynamic principles to ensure that air passes through it smoothly and with minimal resistance. This careful design minimizes turbulence and ensures that the cooling fans can operate efficiently.
2. Large Cross-sectional Area:
By providing a sufficiently large cross-sectional area for air to pass through, the muffler ensures that there is no obstruction to the airflow. This allows the cooling fans to deliver the required airflow for effective part cooling in the 3D printing process.
3. Minimized Back Pressure:
The internal design of the muffler is optimized to minimize back pressure, which is the resistance against the air being pushed through the system. By reducing back pressure, the muffler ensures that the airflow remains consistent and effective, providing the necessary cooling for the 3D-printed parts.
Summary
The Mammoth-3D CPAP Muffler leverages advanced materials and precise engineering to achieve a balance between noise reduction and airflow maintenance for 3D printing part cooling. By employing sound-absorbing materials, optimizing acoustic design, and utilizing the precision of 3D printing, it effectively reduces noise by 13 dB. At the same time, its aerodynamic pathways, adequate cross-sectional area, and minimized back pressure ensure that it maintains 100% airflow, ensuring efficient cooling of the printed parts without additional noise disturbance.

did you try printing the casing with TPU and fuzzy skin for the inner walls?
No the one in the video could be Nylon CF or ASA CF. Don’t remember 😄 I don’t really print fuzzy skin. The CF in the filament does a good job hiding the layer lines
For sure would be nice to have a round shaft, currently planning an AWD high speed H-Bot build, and am considering these motors. The built in thermistors are awesome!
Yes 100%, I did speak to Omran about it but don’t think we will ever see one?! Yes they are. Busy making a new gantry to fit the motors with 30T pulleys 😄👍🏻
nothing to say just loved it <3
Thank you very much :-)

Very very cool! Love videos like that :-) Thanks!
Check out the Celeritas
Have a look at the other videos after this one. So even faster speed printes 👍🏻
Awesome 😮. Where can I find the stl
Thanks. Im still working on the docs. So it will go online soon.
Just finished printing the muffler, but had to order cut to fit foam since we didn't have the aquarium filter that you had listed. Really easy print, but I think I am going to remix the grill to use a PG7 with strain relief for the CANBUS cable. Can't wait to install it this weekend!
Thank you very much for your feedback! Are you in the US? Tasking so that I can look for something similar and update the BOM. Gut do it 😀👍🏻 I love remixing as I do it all the time. Have a look on the mammoth-3D GitHub all the CAD files are online 🤩
already have the whole muffler assembled, i'm just waiting for the pcb for my new xolpap toolhead to arrive
That's awesome!
Great job 👍
Thank you very much!!
Nice job! Love mine!
That is awesome! Do you use the Fish Filter? Or magic cleaning pads?
this is very scare, my cat is sad
@@grahamcracker659 Are you in the US? I will check with Eheim to see what the problem is, that it is so hard to find?
awesome video ! planning on CPAP, def. gonna keep it in mind !

@@3DWolfEngineering Yes I understand. Well it's just the first step to show what can be done. The more people that work on it the better ;-)
Congrats!
Thank you very much :-)
just printed this in ABS! everything was within two thousandths, and looked really crisp : ) printed with a Qidi Q1 Pro.
That's awesome! Maybe you could upload a photo on www.printables.com/model/926983-mammoth-3d-cube/comments So I also get to see it ;-)
Nothing was shown what's so new or special about it. Just some weird puppet logo I can add myself.
Moving the Z Belt to the outside is not new?? It's very new to me and I would say im the first to do so. Or did you see something like this before? Do you have a GitHub link? Thanks
yay!

Is that water cooling for the steppers and hot end?
Yes I use water cooling for the steppers, hotted and 5160 Pro drivers
Hi, could you share info about the extruder, hotend and liquid cooling setups? Thanks!
Lgtm!
If I would know what that means 🤣🤣🤣
Interesting idea! I cannot find the model with the Github link and the discord link seems to have expired

@@measureonceprinttwice Awesome :-)
Can you share the discord link?

Just awesome work as usual
Thanks buddy. Happy you like it 🙂
WHAT THE FUCK!? DUDE! I'm sitting here, trying to figure out how to print a first layer and you do this kind of shit Oo What do you use for bed adhesion!?
whahahaha Yes I did in this print. But it's not for the first layer. It is that the ASA doesn't bond with the PEI Sheet. What I learned over the years. Get a good PEI sheet and stick with on brand, so you know what it can do and what not. The right tool for the job. I tested klicky, BD-sensor, ..... but the best and always consistent is the Beacon probe, not the CN version.
Sorry never gave you feedback about the adhesive I use. Any water based glue stick will do the job. In the US you can find lots. But in Europe hard to find, so im using bamboo lab glue stick.
Impressive 😁
Thank you :-)
Looks like either the heater or the PID loop failed to keep up with the sudden heat loss. If it's the latter, MPC now in DangerKlipper bleeding edge v2 (or its own feature branch) might be able to avoid that. Back when I used PID I had CPAP ramp up slowly over several layers to give the PID controller time to see the heat loss and respond.
Thanks for the Info. Will look into it. I found this dangerklipper.io/Danger_Features.html any other good videos or web sites that I could look at? Or is there only the github?
@@mammoth-3D There's also the Armchair Heavy Industries (formerly Armchair Engineering) D**c*rd where lots of devs and users hang out and can help.
@@daliasprints9798 thank you very much for your feedback. Will check it out.
what special about these compare to something like a superpower
Look super power motors are awesome. That is what im running in my other videos. Kraken has twice the amount of Torque. So the toolhead doesn't always have to be super super light to get better acc. Speed I will have to test and see what I can get.
More torque means a lower top speed right? @@mammoth-3D
@@woutervossebeld4664 Yes that is right. But if you use 30T pulleys with the motors. You have more torque then a super power loo and more speed 🙂
When will these motors be avalible for purchase? I can't find any information online about them.
Are you based in the EU? I only know one shop in the EU that has some in stock.
@@mammoth-3D I am not based in the EU unfortunately. Hopefully they will become more widely available soon!

shaking like an old washing machine with a few screws loose
Whahahaha yes that is so true! You should see the table it’s standing on. Things start falling off from all the shaking :-) I should make a video of that one day.
Doesn't help that it's doing the Voron thing of leaving out 1/4 of the top frame that would have provided a lot more rigidity...
@@daliasprints9798 Maybe im just misunderstanding about the frame. But this is a 300x300 Voron 2.4
@@mammoth-3D I mean how Vorons don't have a full cube frame but leave out an edge at the top front. It detracts a lot from rigidity and AFAICT it's just a "form over function" thing.
@@daliasprints9798er. Not sure why this one doesn't. But mine definitely does. Heh. Pretty sure it's just out of frame
I'm wondering... could I use those printer stepper mounts on my Vz? (Also; love this project)
Thank you very much! I never looked into it. Vz has a fixed gantry and im using a floating gantry. What part do you like. Maybe I can make something new?!
@@mammoth-3D I didn't even register it as floaing gantry - I just thought "that's a really low z height" 😆 In general I'm interested in better ways for tensioning and double shear that fit my Vz330. I know they're working on a double shear design but dunno when that will be released.
@@MrJofArnold Yes I just love floating gantry 🙂 Do you have a link to the double shear that fit my Vz330? If never hear about it. Sorry
@@mammoth-3D They've mentioned it a couple of times in the discord that they are working on it, but no more info than that I'm afraid
@@MrJofArnold It could also just mean that they will put two pulleys on one shaft?! Hard to tell. I do the same. Just to safe space. We will see what will come out at the end. Yes the belt tensioning system I made was, I don't need to loosen motor mounts and I don't tension directly on the motor shaft! And that is how the mammoth gantry was made. :-)
Hello! i first thought that the 1 Set x Eheim 2617080 Filter Cartridges for Pickup 60 from the BOM is the noise dampening material but it says 1x and the 2 cubes in the box are only 10x10x10mm so what are they for and what would you recommend to dampen the noise/stuff in the muffler?
Hello, I think you had a look at this link? www.amazon.de/Eheim-2617080-Filterpatronen-für-Pickup/dp/B0014FKK9G It's 100% not 10x10x10mm!!! If you go down on the link you will see Product Dimensions 6 x 12 x 8 cm; 30 g You can look for the CN version. But the Eheim is the one I use in my mufflers on all my printers.
so u went with vz toolhead
for know :-) As the gantry is new and also to show that you could fit the vz toolhead on the printer. But it will only be a true mammoth if the mammoth toolhead is on it ;-)
nailed it
whahaha the test was to print a fast bench and not to blow it of the bed 🙂
Too much cooling?
Yes 100%. Im printing @1000mm/s so will have to test a bis to get the right cap flow. ;-)
@mammoth-3D do you have a github with your designs? I love your cpap set up.
@@TheMostH8D github.com/Mammoth-3D/Mammoth-FDM-MODs?tab=readme-ov-file The new Gantry will be online soon, and the toolhead that is on the printer in this video is a VZBOT Toolhead. So just google it.
@mammoth-3D I wanted to do that gantry set up but decided to go with a vz extruder and lsd on an archetype toolhead with 9mm belts and awd. Your set up is super clean.
@@TheMostH8D that setup will work good as well. Just check that your gantry doesn't get super heavy with all the bearings for 9mm. I don't think we need 9mm belts. I tested this printer at 1000mm/s 50k acc no problem.
I knew 3d printing would get popular one day :)
It's 100% the way to go. Easy to update if you need to.
Hey I wanted to ask where the foam goes as I'm confused. I have everything else assembled but no idea where this 10x10 pieces go
Hey. It will go into the muffler. If you need more help. Mail me info@mammoth-3d.ch
Dein LED Mount ist nocht Beacon3D-kompatibel oder?

I don't understand 🙂
I just got my foam in the mail today and I gotta say, you really nailed it man. It was insane how much noise was reduced. It's not dead silent by any means, but it is definitely "home office friendly". I think I'm going to modify it slightly to add a shroud over the blower itself and stuff it with foam; I've seen other cpap mounts do this and I wonder what kind of improvements it could make. I also want to print some mounts in flex material to decouple the housing from the frame of the printer so I can possibly further reduce noise. Very well done, excellent model.
Im very happy to hear you like it. 😁 Let me know how it’s going. All the CAD files are online. So you should be good to start. Im also thinking about a carbon filter in V2. So you don’t need a separate one. What do you think?
@@mammoth-3D I'd be thrilled to see a carbon filter in V2. Maybe it's possible to print a cylinder shaped double walled design to plug onto the inlet in the chamber.

10 out of 10 for design. disqualification for weight. Get rid of canbus and tap, whats left will be vz bot
I don’t use Can Bus or TAP, but that is what users are looking for. And yes it’s based off the VzBot. But to fit a Voron, as the VzBot Toolhead doesn’t really fit on the Vorons. If you are looking for a Voron Toolhead you can find it on my GitHub github.com/Mammoth-3D/Mammoth-FDM-MODs
