I've been 3D printing sound panels for a few months and found the same issue: you need absorbption as well as diffusion. With a mixture of laser cutting, 3D printing, and thinning out my t-shirt collection I've found similar results. Love what you've done here, I'm going to have to give it a try, just at a smaller final product. I'd give my left kidney for a Prusa XL for the size. Serious, Josef, my left kidney.

Honest impression from someon listening with headphones? The processed audio is worse than the unprocessed one. It's hrd to describe what's going on exactly, but it sounds like a flanger tracking the speech trying not to get caught. Truly awful once you hear it.
See I cannot hear this. I've had a grand total of 2 people say they hear "something" off in my audio but they cannot truly explain it. My hearing is absolutely damaged from years of metal fabrication. But unfortunately I will never be able to have someone edit my audio while I'm making videos to confirm it is perfect for everyone. I especially cannot justify doing so if it is for .1% of viewers. I'm not saying you are wrong, I simply cannot address this issue.

So you gave me an idea. You mentioned trapping, captureing, and stopping sound waves. 3D printing enables structures and designs that are very difficult to execute any other way. What if you 3D printed sound panels which have complex overlapping stepped surfaces? For example, cone structures shaped sort of like Christmas trees with various branch diameters that overlap neighbors. Sound waves bounce in, but then when they try to reflect back out, they hit a branch above. Like Tesla valves for sound waves essentially. I wonder how effective this could be.
Very worth exploring though those structures have a risk of bouncing the sound back out. If I knew more about this stuff (or more so had a better studio space to test with better microphones) it could be a neat testing process to see what difference there is. Maybe eventually.
FYI, the sound isn’t “trapped” in your foam. It’s actually hits the foam and it’s converted into heat at a micro level. So technically it’s converting the sound into heat energy
This is a great idea. One thought if you wanted to save on fabric, you could just make a fabric cover for the grille and 3d print a panel for the back that you could add a french cleat or a integrated hanger for other wall mounting options.
Let's be clear. You didn't 3D-print an acoustical product; you printed a decorative holder for an acoustical product. The acoustical properties come from the Rockwool. The 3D-printing is entirely incidental. I mean, it looks nice but contributes nothing to the dissipation of acoustical energy.
20% density gyroid infill for the absorbing panel, and a 30% rectinlinear infill for an aesthetic mesh front, might be almost as good at sound absorbtion compared to the foam and fabric... but the print time to cover that whole room would be nuts. And it wouldn't be cheap either. You could print cool images onto the meshes with hueforge though, do a big mural
@@32BitJunkie There might be a case for 3D-printed acoustical treatment but I'm highly skeptical that the end product would be a broadband absorber. There's a reason why Rockwool is the best material of its kind. It's properties would be essentially impossible to replicate with FDM. Maybe resin or sls could be used but it'd be insanely expensive and probably nowhere near as effective. FDM could be useful in printing molds for diffusers or perhaps even some kind of novel helmholtz resonator. Broadband absorption? Highly unlikely.
Nice man! I did the same thing, but wrapped in fabric, instead of infill on the front. Yours, as usual, look much better ;) Good work. Also, CONGRATS on 50K bro!
This is such a sick idea, and good timing too. Our cats have decided that foam tiles are delicious and fun to tear off the walls 😂😭 need a new solution
I was literally just toying with this idea the other day and looking around online for some. found some diffusers that are really sweet and because its 3d modeled the person who designed them was able to do all the sound testing in software and has different versions to target different frequency ranges its super interesting but they were very time consuming prints these are much less due to the hollow design for the filler material so im gonna give these a shot.
FYI I think it’s important to mention that although you did your research it’s clear you don’t quite understand everything. Dispersion panels work very well when they’re installed correctly. They aren’t gonna do anything when 80% of your wallet is still flat and exposed. They need to be placed in a critical area where reflections occur to then scatter the reflections. So the theory is correct but the application is incorrect
This was a really cool video! I'm glad you came to actual audible results! 3D printing and audio are a combo that should be explored more. I've designed several headphones on Printables with an emphasis on audio quality and I'm disapointed that its basically just me, Headamame and Ploopy making interesting 3d printable headphones.
Nice concept, you could totally just put Rockwall on the walls and print the very pretty hexagonal sound defusing face to cover it, saving a considerable amount of time and filament. You could even make it so the hexagonal pattern locks together and just stitched to the lining material.
DIY perks made a video some time ago and after testing he found out himself that cheap towels work incredibly well to damp reflections. It’s one of the projects in my list
you need to cover 30% of all 6 surfaces to hear a big difference. Right now it sits on about 15% of one wall, so it is about 2% coverage. This is why you do not hear a difference. If you would like to have more impact also - make them thicker, and/or mount them not directly on the wall, but with a gap. Also to max their effect mount them in the place of first and second reflection in the first place. If you talk to the monitor - wall behind is ok, then spots on the sides and the ceiling, then the back spots
These came out great! Built something similar out of wood and used speaker grill cloth for the front. Will have to try 3D printed ones soon. Looking forward to seeing the other office projects!
Thank you so much. I was gonna make some wooden ones just to have them (and not do a video) but then the inspiration struck. My design files will be release SOON (yet today) and linked in the description when I do.
Awesome, I appreciate it! I feel like we think similarly haha. I used carpet underlayment (cause I got it for free) and old T-shirts/rag for the sound absorption as well. Build video is on my page. Always cool to see how different people tackle similar challenges!
that is literally the exact thing I thought they would be good to make into a sound panel, but I still think it needed something more like LEDs behind them in a way or something that isn't over the top but dope.
That was a thought I had halfway through and didn't have time to implement this time. Or I was thinking about making some add-on border pieces that have LEDs in them and are modular to whatever configuration someone may setup. Something I have to play with as I have a bunch of WLED controllers here waiting for a project to integrate with. Thanks for the input!
That is a playback issue on your end. The audio in this video is recorded direct to camera and is 100% in sync on my end. In the original clips, editing software, exported video on my PC. Also when I watch it on UA-cam on my TV, phone, and computer, all in sync. Some browsers are known to have audio sync issues with UA-cam, I'd look into it if I were you.
Omg yes I went straight to the comments. Did seem to sync up after a bit but after seeing the start out of sync it not just feels like it's dubbed over and that ain't his own voice 😂 of course judging by the comments from The creator this is "my fault" dude really learns how to take criticism. Not everything is an attack 🤦♂️
I like how your brain misunderstood the prusa poster art but interpreted in an even better way by adding new functionality to the paper posters. Infill doesn’t look awesome 👍

Shape. Yes, I've heard it: shape :) Cool design. I like it!
I'm a big fan of using over-extruding to make larger objects. The volcano nozzles I use have flat bottoms so my 0.6 can over-extrude roughly 1.1mm reliably
When it comes to home theater or music listening applications, you actually want a good balance of sound absorption and sound diffusion. Too much absorption will lead to a very dull and lifeless sound. I don't think there is such a thing as too many diffusion panels, but there are significant diminishing returns once you go outside of a few well-placed diffusion panels.
amazing video! do you think the command strips will tear the paint off the wall? i'm looking for sound treatment for my secondary filming location (I'm using sennheiser mke50 which cuts down on a lot of reverb)...this home improvement video series is amazing, I already installed a DIY 3d printing ventilation system in my workshop based on your recommendation using a super strong inline fan, its super overkill and super amazing
The strips may do that, but I fully intend to completely repaint my office, so I'm not bothered if they do. I will see when the time comes (it will likely be part of a video). Rad on the ventilation setup, that is an upcoming project in the main studio as well! I have and love my Deity shotgun mics as they definitely help with Reverb, but lately I'm moving around too much to use them. Maybe I can get back to using them once the studio is a little more set.
This is definitely a project that shows the (size,time) limits of 3d printing. Sure you can do it but it’s dramatically cheaper and quicker to do it in wood and can subjectively look better.
Entirely subjective though. As a creator that works with 3d printing often, I think this looks vastly better than any wood ones I've seen. The only thing I've seen close is ones that have flat wood panels laser cut and laid over them, which has no diffusion effect, and I think looks kind of cheap. I'm not saying this is an efficient system. If you just want panels that "work" then wood is absolutely superior, but I wanted something to pull double duty, look good AND work.
@@JaeTLDR1 Stop making assumptions. If I made these in wood I would have to buy wood tools. Meanwhile I have a larger (not Prusa XL size but large enough) printer, plenty of old t-shirts, some leftover insulation. This is a no-brainer project when the BOM of what it actually costs me is about 3 EUR per panel in "new" material and energy and I can print off one of these overnight for the next week. Yes, its probably much faster in wood, but so would be just ordering professionally made ones online.
I mean 3d printing is parallel working, in those 45 hours your on hand time is like 45 minutes max. Is it cheaper with wood? Yes if you have the knowledge and power tools, but 3d printing is still a very viable option
great video, keep us posted on the ceiling stuff! Also I love how apparently everyone is an acoustics engineer when someone does a video on that matter 😂
0:30 maybe I would notice if I was using my desktop headphones but I sure don't hear any major issues on my phone unless I crank the volume. Real rooms have character to them and that's ok.
Very nice looking. Do you think if you put the command strip areas near the top corner would they sag less? Looking forward to the smaller print volume ones
Smaller print volume version is available! than.gs/m/1231787 As for the command strips, if I had just rotated the panels 30 degrees it would be a non-issue. That would have put the command strips at the top-right & bottom-left. I realized that this morning sadly, ha. But I did put 3 command strips on the first one I put up in the big section by my desk, that helped a lot (one at the top and 2 on the sides).
Shag carpeting hung on the walls has been audio tested to be better than fancy acoustic foam, besides being tons cheaper. It's those thousands of soft fibers absorbing the sound waves. Someone on an underwater ROV forum was asking a few years ago for help 3D printing a 4" pipe. I told him, 3D printing is for strange brackets or gears you can't find anywhere else. 4" plastic pipe you buy at the hardware store.
Like most UA-camr's out there you are getting the foam panels wrong. Through no fault of your own I am sure because of the way they are advertised. (As sound dampening panels) Which they are not. They can alter the frequency response of a room (a little) but other than that, they are trash. The panels you are printing have a wave reflecting property that actually disperse the wave nicely when it hits them. Breaking your volume (the pressure of your wave) down into smaller waves and dispersing the sound. Hung blankets by the way are perfect for this, the sound hits them, disperses, then hits the wall behind them and gets dispersed again making them the most off-the-shelf effective tool for sound dampening or deadening a room. In the recording studio we use heavily curtained walls with panels behind them that break up the waves. Panels not unlike the ones you are printing here.
I do, and HAVE! The design files are here, including 3MF files with all my slicer setting tweaks for how I intend them to be printed: than.gs/m/1231772
Oh man great video! This means you can make a translucent cover for that could defuse some LED strips that you put inside. Ahhhh i want a 3d printer haha! Keep up the awesome content
This video is so well made that you just earned yourself a subscriber Also, are you sureeee you said "shape" 😅 I also love how you were helping someone who has no clue/new to printing or how their printer/slicer worked in the comment section on the Thangs website Im also new to 3d printing myself. I had to figured a lot of things myself, and I have more to still learn I have a Creality Ender 3 V3, I didn't do any research about it, which I should have, I just knew that Creality and Bamboo were the more recognized brands, so I randomly chose. Then I started seeing some videos that didn't look good (it was too late i already purchased it 😅) I was relieved when I got mine, I guess they made a newer gen/iteration because I noticed how most of those issues that ppl were talking about were fixed/changed, and im happy with it 😊
@mandicreally Are you concerned at all with breathing in the rock wool? I know they are "enclosed" but I've always been concerned about it long term. I've created similar panels with carpet foam before, and it worked pretty well (had to stack a bunch together).
No, TPU is still far too hard of a material. The sound waves need to be able to penetrate into the material where they become trapped as they try to vibrate around inside. I meant to address this very thing in the video but it slipped my mind in the final stages. TPU just isn't porous or soft enough to do the job. Even just bunched up TShirts wadded inside likely would make a difference honestly. Maybe some of that "Vairshore" TPU that "foams" but even then I can't see sound waves penetrating deep enough. Ideally the panel should have an open back (as mine do) so sound waves can travel through the material, bounce off the wall, then get come back into the material and get trapped in the process. You want a fine line of "sound can pass through this" and "sound gets trapped by this". I'm sure this is a much deeper topic than I have any knowledge on.
No it really didn’t make a difference. The PC is watercooled and air blows up out the top. Also the side panel is not on it so all the noise has a clear path too much at the desk sadly. Very little goes out the back on this machine.
IME 'split into objects' gives them all physics and will settle all parts to the build plate. I would recommend 'split to parts' which leaves them in place while still letting you change the settings without letting them move freely, as it leaves them all as the same object
I would normally recommend "Split to Parts" but this particular geometry had MASSIVE errors when doing so. I cannot explain why but this particular design just does not slice properly when set that way. When using "Split to Objects" it works flawlessly. The design has all the intended faces against the build plate already anyway (I ALWAYS orient parts for printing) so it works just fine in this design. I made it with this in mind. You can find the files here: than.gs/m/1231772
Honestly i think that maybe audiophiles care what it sounds like but im just happy if i can hear and understand you i notice very little differences between all your audio clips but if i would pick i liked the unprocessed audio better the processed has a higher hiss to it than the unprocessed
400g per panel, so whatever your filament costs are on that. For what I used? $20.99 a Kg, so $80-90? Not as cheap as wood, but factoring in the look and comparing to commercially available panels the expense isn't terrible.
Hallo, ich komme aus Deutschland mein Englisch ist nicht so gut deswegen fand ich dein Video richtig cool dass es übersetzen lassen hast bitte mehr davon, dass sie das Ganze so hoch. Das Konzept, was du gemacht hast, fand ich auch Mega genial. Ich glaub das werde ich auch probieren zu drucken. .
I use AutoDesk Fusion. It has a free for hobbyists tier that allows a lot of design work for those starting out. Just not a sponsor so I’m trying to dial back how much I promote them for free.
I’m on UA-cam to watch something. If it’s in 720p I’m definitely unhappy and left rubbing my eyes thinking they’re making things blurry. Once sound and video reach a certain point, they’re fine. 60fps is a win though
Did have a thought when you used the old t-shirts. Could be a good way to do sound deadening *and* display those old band or tour t-shirts that are too old or broken to wear but you can't bring yourself to throw out! :P
Too "busy" of a look for what I'm going for. I was selective and chose shirts I wouldn't miss nor care about displaying. I've thought of doing a shirt project like that, but that would have to be more like "patchwork quilt" or something. Maybe a fun project for our living room or something.
Honestly, didn’t think of it. Goal was more standalone, but that isn’t a bad idea. Allow them to function more as a unit. Only problem is it would require numerous versions unless you were fine with seeing holes all around the edges. To have closed sides on some and not others would mean 4-7 designs in total. Maybe V2.
@ I think if you did a channel system with a stand alone channel clips. I think you can do one version. If no clip and a male and female connector that’s when you get into versions.
It's a cool project for sure, I only wonder why you didn't use multiple infill patterns to improve the diffusion/scattering effect and randomize the look more. I know you can rotate them, but there's so many aesthetically pleasing infill patterns and randomizing widths and angles could have given a better end result for both look and performance IMO.
Only one or two infill patterns can actually self support enough to work for this. Adaptive Cubic is by far the best one. I meant to touch on that but forgot as the week dragged on. Gyroid may work, and Grid, but idk if any others will as they don’t interconnect enough.
I haven't played with a scaled down version yet. It SHOULD be doable, but I will have to test. I just uploaded the default design version. I will see about a 3MF of the scaled version. Current version: than.gs/m/1231772 (scaled version will land here if it works)
It isn’t IDEX yet nor fully tuned in yet. Also sure I could print bigger panels on that but far fewer folks have a machine that big. Folks may not have an XL but a 400mm machine isn’t as uncommon. I knew I wanted to release this design so folks could make them too.
I get the whole youtube studio esthetics but to have looks be a main goal or as much of a goal as working seems odd because regardless you compromise function for form
Oh I will be. Mostly on the Mandic Labs channel, likely in a stream series or a tech focused video. If I like it I'm sure it will appear in more videos.
Sounds like we should just be printing cool-shaped frames that you can stretch moving blanket hexagons across, then they would look good, be cheap, and be effective, with, like, *way* less work.
@@ReclaimerTyphoon moving blankets aren’t nearly as effective as the insulation I used. They are just a good stop gap if you cannot afford to build things with better materials. Layering them may help, as it is the depth of the material that is playing a part in the roll. That wall I referenced in the beginning is 6” thick to maximize the insulation material and help improve the effect. A Less than 1/2” thick moving blanket really can’t do the same unless layered over and over and over.

And it wouldn't be cheap either. You could print cool images onto the meshes with hueforge though, do a big mural
@@32BitJunkie not even close
especially since the infill is inside the 3d print
the sound cant really get to it
@@32BitJunkie There might be a case for 3D-printed acoustical treatment but I'm highly skeptical that the end product would be a broadband absorber. There's a reason why Rockwool is the best material of its kind. It's properties would be essentially impossible to replicate with FDM. Maybe resin or sls could be used but it'd be insanely expensive and probably nowhere near as effective.
FDM could be useful in printing molds for diffusers or perhaps even some kind of novel helmholtz resonator.
Broadband absorption? Highly unlikely.
Thanks for this, saved me having to watch the video
A typical small room will require about 20% of its surfaces to be treated with broadband absorbers in order to achieve a desirable RT60.
Nice man! I did the same thing, but wrapped in fabric, instead of infill on the front. Yours, as usual, look much better ;) Good work.
Also, CONGRATS on 50K bro!
This is such a sick idea, and good timing too. Our cats have decided that foam tiles are delicious and fun to tear off the walls 😂😭 need a new solution
They knew I had something in the works, haha. Working on the release version right now (well after I finish comments). Files should be up yet today.
On Thangs and Printables now: www.printables.com/model/1119210-real-3d-printed-sound-panels
i just watched this with my son and he wanted to let you know that this is amazing
Thank you very much, I appreciate the kind words.
command strips: When you want something to fall and shatter, but not right away..
I was literally just toying with this idea the other day and looking around online for some. found some diffusers that are really sweet and because its 3d modeled the person who designed them was able to do all the sound testing in software and has different versions to target different frequency ranges its super interesting but they were very time consuming prints these are much less due to the hollow design for the filler material so im gonna give these a shot.
FYI I think it’s important to mention that although you did your research it’s clear you don’t quite understand everything. Dispersion panels work very well when they’re installed correctly. They aren’t gonna do anything when 80% of your wallet is still flat and exposed. They need to be placed in a critical area where reflections occur to then scatter the reflections. So the theory is correct but the application is incorrect
This was a really cool video! I'm glad you came to actual audible results! 3D printing and audio are a combo that should be explored more. I've designed several headphones on Printables with an emphasis on audio quality and I'm disapointed that its basically just me, Headamame and Ploopy making interesting 3d printable headphones.
Built a pair of Satyr 1 a while ago and it's been phenomenal
@@hoshiai299 that's awesome! you should check out the new v3 headband design, it adds folding and some customization!
I really like this idea! This is a nice mix of materials! Definitely need more of them printed. Hexagons are the bestagons!!!!
Nice concept, you could totally just put Rockwall on the walls and print the very pretty hexagonal sound defusing face to cover it, saving a considerable amount of time and filament.
You could even make it so the hexagonal pattern locks together and just stitched to the lining material.
They look great as decorative pieces as well as being functional. Thank you for sharing the files too!
DIY perks made a video some time ago and after testing he found out himself that cheap towels work incredibly well to damp reflections. It’s one of the projects in my list
you need to cover 30% of all 6 surfaces to hear a big difference. Right now it sits on about 15% of one wall, so it is about 2% coverage. This is why you do not hear a difference. If you would like to have more impact also - make them thicker, and/or mount them not directly on the wall, but with a gap. Also to max their effect mount them in the place of first and second reflection in the first place. If you talk to the monitor - wall behind is ok, then spots on the sides and the ceiling, then the back spots
These came out great! Built something similar out of wood and used speaker grill cloth for the front. Will have to try 3D printed ones soon. Looking forward to seeing the other office projects!
Thank you so much. I was gonna make some wooden ones just to have them (and not do a video) but then the inspiration struck. My design files will be release SOON (yet today) and linked in the description when I do.
Awesome, I appreciate it! I feel like we think similarly haha. I used carpet underlayment (cause I got it for free) and old T-shirts/rag for the sound absorption as well. Build video is on my page.
Always cool to see how different people tackle similar challenges!
that is literally the exact thing I thought they would be good to make into a sound panel, but I still think it needed something more like LEDs behind them in a way or something that isn't over the top but dope.
I did a similar thing a couple months back with some testing. And Gyroid infill seems to work the best for my experience.
I was tempted to try Gyroid but preferred the look of Adaptive Cubic. Maybe when I do some more I’ll do a few Gyroid. Thanks
They look really cool. LEDs installed in the next ones maybe?
That was a thought I had halfway through and didn't have time to implement this time. Or I was thinking about making some add-on border pieces that have LEDs in them and are modular to whatever configuration someone may setup.
Something I have to play with as I have a bunch of WLED controllers here waiting for a project to integrate with. Thanks for the input!
You know what's worse than bad audio?? When audio and video that are not property synced.
That is a playback issue on your end. The audio in this video is recorded direct to camera and is 100% in sync on my end. In the original clips, editing software, exported video on my PC. Also when I watch it on UA-cam on my TV, phone, and computer, all in sync. Some browsers are known to have audio sync issues with UA-cam, I'd look into it if I were you.
I thought it was only me 😂. It's off a little bit.
@@vodkanarancs1 Try another browser. I've checked it numerous ways, it is in sync on my end. UA-cam can have sync issues from time to time.
Yeah, I don't see that issue so far.
Omg yes I went straight to the comments. Did seem to sync up after a bit but after seeing the start out of sync it not just feels like it's dubbed over and that ain't his own voice 😂 of course judging by the comments from The creator this is "my fault" dude really learns how to take criticism. Not everything is an attack 🤦♂️
I like how your brain misunderstood the prusa poster art but interpreted in an even better way by adding new functionality to the paper posters. Infill doesn’t look awesome 👍
Shape. Yes, I've heard it: shape :) Cool design. I like it!
😅😅😅
I'm a big fan of using over-extruding to make larger objects. The volcano nozzles I use have flat bottoms so my 0.6 can over-extrude roughly 1.1mm reliably
I really dig the color scheme!
Spiffy! Not directly relevant for me, but it does remind me that I need to research speaker boxes. And it was fun to watch whilst eating dinner.
Thanks for watching and commenting. I appreciate all kinds of content about stuff I will likely never do, so I'm glad when others can too.
When it comes to home theater or music listening applications, you actually want a good balance of sound absorption and sound diffusion. Too much absorption will lead to a very dull and lifeless sound. I don't think there is such a thing as too many diffusion panels, but there are significant diminishing returns once you go outside of a few well-placed diffusion panels.
this guy knows what he's talking about 👍
amazing video! do you think the command strips will tear the paint off the wall? i'm looking for sound treatment for my secondary filming location (I'm using sennheiser mke50 which cuts down on a lot of reverb)...this home improvement video series is amazing, I already installed a DIY 3d printing ventilation system in my workshop based on your recommendation using a super strong inline fan, its super overkill and super amazing
The strips may do that, but I fully intend to completely repaint my office, so I'm not bothered if they do. I will see when the time comes (it will likely be part of a video).
Rad on the ventilation setup, that is an upcoming project in the main studio as well! I have and love my Deity shotgun mics as they definitely help with Reverb, but lately I'm moving around too much to use them. Maybe I can get back to using them once the studio is a little more set.
Try Foaming TPU as infill and see if it work without the soundinsulation
resize x&y to 70% and it will fit on the bambulab build plate make sure you uncheck uniform scaling to keep the z height
I'm working on a version for Bambu & Prusa Mk4 printers RIGHT NOW, but yes scaling to 70% is a quick hack.
Would've been great to hear a before and after. Nice project - thanks.
This is definitely a project that shows the (size,time) limits of 3d printing. Sure you can do it but it’s dramatically cheaper and quicker to do it in wood and can subjectively look better.
Entirely subjective though. As a creator that works with 3d printing often, I think this looks vastly better than any wood ones I've seen. The only thing I've seen close is ones that have flat wood panels laser cut and laid over them, which has no diffusion effect, and I think looks kind of cheap.
I'm not saying this is an efficient system. If you just want panels that "work" then wood is absolutely superior, but I wanted something to pull double duty, look good AND work.
@ absolutely, for the average person the 3d printing at this scale is not super sustainable imo. For you this works
@@JaeTLDR1 Stop making assumptions. If I made these in wood I would have to buy wood tools. Meanwhile I have a larger (not Prusa XL size but large enough) printer, plenty of old t-shirts, some leftover insulation. This is a no-brainer project when the BOM of what it actually costs me is about 3 EUR per panel in "new" material and energy and I can print off one of these overnight for the next week. Yes, its probably much faster in wood, but so would be just ordering professionally made ones online.
I mean 3d printing is parallel working, in those 45 hours your on hand time is like 45 minutes max. Is it cheaper with wood? Yes if you have the knowledge and power tools, but 3d printing is still a very viable option
Great video.........but what is your CAD of choice?
Autodesk Fusion is my goto. Just trying to stop promoting brand and products aren’t sponsoring projects.
Great idea! Thanks for sharing the links!
I'm new here, and i've never seen some one pull of the chops so well!
great video, keep us posted on the ceiling stuff!
Also I love how apparently everyone is an acoustics engineer when someone does a video on that matter 😂
this is a fantastic idea... I think I will do it as well.. maybe experiment with different patterns like slats or other shapes. Thank you.
Great job dude, don’t listen to the trolls in the comment section.
Criticism is good for people
0:30 maybe I would notice if I was using my desktop headphones but I sure don't hear any major issues on my phone unless I crank the volume.
Real rooms have character to them and that's ok.
Very nice looking. Do you think if you put the command strip areas near the top corner would they sag less? Looking forward to the smaller print volume ones
Smaller print volume version is available! than.gs/m/1231787
As for the command strips, if I had just rotated the panels 30 degrees it would be a non-issue. That would have put the command strips at the top-right & bottom-left. I realized that this morning sadly, ha. But I did put 3 command strips on the first one I put up in the big section by my desk, that helped a lot (one at the top and 2 on the sides).
I haven't done much with foaming filaments, but always wondered if they would be a good material for sound deadening
0:52 is this Stock footage or do you already have a Prusa Core?
Neither! It was the Core One on display at SMRRF earlier this month, I just used my own “stock video”. I wishhhh.
@@MandicReally I legit had the same reaction. I was like, HOW DID HE GET IT SO QUICKLY??
Shag carpeting hung on the walls has been audio tested to be better than fancy acoustic foam, besides being tons cheaper. It's those thousands of soft fibers absorbing the sound waves.
Someone on an underwater ROV forum was asking a few years ago for help 3D printing a 4" pipe. I told him, 3D printing is for strange brackets or gears you can't find anywhere else. 4" plastic pipe you buy at the hardware store.
Yeah but you can’t get it in red though lol 😂
Theses are the best ones I have seen by far.
Like most UA-camr's out there you are getting the foam panels wrong. Through no fault of your own I am sure because of the way they are advertised. (As sound dampening panels) Which they are not. They can alter the frequency response of a room (a little) but other than that, they are trash. The panels you are printing have a wave reflecting property that actually disperse the wave nicely when it hits them. Breaking your volume (the pressure of your wave) down into smaller waves and dispersing the sound. Hung blankets by the way are perfect for this, the sound hits them, disperses, then hits the wall behind them and gets dispersed again making them the most off-the-shelf effective tool for sound dampening or deadening a room. In the recording studio we use heavily curtained walls with panels behind them that break up the waves. Panels not unlike the ones you are printing here.
Do you plan on making these designs available? If you do can you include print settings you changed pleaseeeee
I do, and HAVE! The design files are here, including 3MF files with all my slicer setting tweaks for how I intend them to be printed: than.gs/m/1231772
@MandicReally thank you thank you thank you
Spread them around the corners and the 90 degree angles. Your most acoustic interference will be in those areas since they bounce around more.
protip: scream into an absorber. if you can still hear too much from the other side its basically just trash.
Literally was thinking about this last night!
Oh man great video! This means you can make a translucent cover for that could defuse some LED strips that you put inside. Ahhhh i want a 3d printer haha!
Keep up the awesome content
This video is so well made that you just earned yourself a subscriber
Also, are you sureeee you said "shape" 😅
I also love how you were helping someone who has no clue/new to printing or how their printer/slicer worked in the comment section on the Thangs website
Im also new to 3d printing myself. I had to figured a lot of things myself, and I have more to still learn
I have a Creality Ender 3 V3, I didn't do any research about it, which I should have, I just knew that Creality and Bamboo were the more recognized brands, so I randomly chose.
Then I started seeing some videos that didn't look good (it was too late i already purchased it 😅)
I was relieved when I got mine, I guess they made a newer gen/iteration because I noticed how most of those issues that ppl were talking about were fixed/changed, and im happy with it 😊
@mandicreally Are you concerned at all with breathing in the rock wool? I know they are "enclosed" but I've always been concerned about it long term. I've created similar panels with carpet foam before, and it worked pretty well (had to stack a bunch together).
Is there a amazon link for those command strips? I use so many of them and I'm looking for a bulk option that aren't crappy quality
I don't use command strips often so I cannot speak to the quality compared to legit ones, but here is the link: amzn.to/40ImFGT (affiliate link)
Been watching your videos since your first tiktok account got banned. Love the videos!
Holes in your ear threw me off a sec 😲
Aw your pets are wonderful😻
Aziz LIGHT! Lighting would be a close second. 🤣
Would TPU instead of infill and rockwool work too?
No, TPU is still far too hard of a material. The sound waves need to be able to penetrate into the material where they become trapped as they try to vibrate around inside. I meant to address this very thing in the video but it slipped my mind in the final stages. TPU just isn't porous or soft enough to do the job. Even just bunched up TShirts wadded inside likely would make a difference honestly. Maybe some of that "Vairshore" TPU that "foams" but even then I can't see sound waves penetrating deep enough.
Ideally the panel should have an open back (as mine do) so sound waves can travel through the material, bounce off the wall, then get come back into the material and get trapped in the process. You want a fine line of "sound can pass through this" and "sound gets trapped by this". I'm sure this is a much deeper topic than I have any knowledge on.
They do make a lightweight PLA that is foaming like formula. Not sure about hardness though.
This may be a good option for a DIY studio, if not covering the whole room at least a little station for the vocalist
When you have your PC as a Standing PC..
Do the panels make your PC a bit more Quiet? (cause they are kinda at the Air Out at the back of your PC)
No it really didn’t make a difference. The PC is watercooled and air blows up out the top. Also the side panel is not on it so all the noise has a clear path too much at the desk sadly. Very little goes out the back on this machine.
@@MandicReally why no side panel?
IME 'split into objects' gives them all physics and will settle all parts to the build plate. I would recommend 'split to parts' which leaves them in place while still letting you change the settings without letting them move freely, as it leaves them all as the same object
I would normally recommend "Split to Parts" but this particular geometry had MASSIVE errors when doing so. I cannot explain why but this particular design just does not slice properly when set that way. When using "Split to Objects" it works flawlessly. The design has all the intended faces against the build plate already anyway (I ALWAYS orient parts for printing) so it works just fine in this design. I made it with this in mind.
You can find the files here: than.gs/m/1231772
Hell yeah! Happy Holidays dude!!
Honestly i think that maybe audiophiles care what it sounds like but im just happy if i can hear and understand you i notice very little differences between all your audio clips but if i would pick i liked the unprocessed audio better the processed has a higher hiss to it than the unprocessed
What was the cost of each in filament to print?
400g per panel, so whatever your filament costs are on that. For what I used? $20.99 a Kg, so $80-90? Not as cheap as wood, but factoring in the look and comparing to commercially available panels the expense isn't terrible.
Hallo, ich komme aus Deutschland mein Englisch ist nicht so gut deswegen fand ich dein Video richtig cool dass es übersetzen lassen hast bitte mehr davon, dass sie das Ganze so hoch.
Das Konzept, was du gemacht hast, fand ich auch Mega genial. Ich glaub das werde ich auch probieren zu drucken. .
Have you looked Into Auralex sound
What software are you CADding in?
I use AutoDesk Fusion. It has a free for hobbyists tier that allows a lot of design work for those starting out. Just not a sponsor so I’m trying to dial back how much I promote them for free.
Pretty similar to other common, functional designs that just use a couple pieces of wood stapled together to form a shallow box.
@@cyphre yes, I said that at 4:57
I’m on UA-cam to watch something. If it’s in 720p I’m definitely unhappy and left rubbing my eyes thinking they’re making things blurry. Once sound and video reach a certain point, they’re fine. 60fps is a win though
Did have a thought when you used the old t-shirts.
Could be a good way to do sound deadening *and* display those old band or tour t-shirts that are too old or broken to wear but you can't bring yourself to throw out! :P
Too "busy" of a look for what I'm going for. I was selective and chose shirts I wouldn't miss nor care about displaying. I've thought of doing a shirt project like that, but that would have to be more like "patchwork quilt" or something. Maybe a fun project for our living room or something.
lololol, sound panels! i thought it was solar panels.....still learned something though. Thank you
You need transfer tape! It'll still come off... not as easy but it should hold them taught
black nylon stockings instead of speaker material? I think it will be easy, cheap and efficient.
This is such an awesome idea. Now I know why you sound like Shaft in all your videos.
i would totally vacuum form these
then just cut out the cutouts
and paint the grills
you could make dozens in an afternoon
We have to try embedding Helmholtz resonators into a 3d printed sound panel design.
Any reason you didn’t make channels so they can connect to each other?
Honestly, didn’t think of it. Goal was more standalone, but that isn’t a bad idea. Allow them to function more as a unit. Only problem is it would require numerous versions unless you were fine with seeing holes all around the edges. To have closed sides on some and not others would mean 4-7 designs in total. Maybe V2.
@ I think if you did a channel system with a stand alone channel clips. I think you can do one version. If no clip and a male and female connector that’s when you get into versions.
It's a cool project for sure, I only wonder why you didn't use multiple infill patterns to improve the diffusion/scattering effect and randomize the look more. I know you can rotate them, but there's so many aesthetically pleasing infill patterns and randomizing widths and angles could have given a better end result for both look and performance IMO.
Only one or two infill patterns can actually self support enough to work for this. Adaptive Cubic is by far the best one. I meant to touch on that but forgot as the week dragged on. Gyroid may work, and Grid, but idk if any others will as they don’t interconnect enough.
@@MandicReally 3d honeycomb also works well for prints like these
I had to restart after 2minutes because I noticed I didn’t listen to him but was only focussing on those earholes
I’m trying the same thing with the ‘Einstein tile’ shape and printed out of varioshore tpu
Command strips! Love them.
They are just a double sided adhesive tape, sold with 1000% margin.
Could you scale it down to 256 and split it into plates? as a .3mf?
I haven't played with a scaled down version yet. It SHOULD be doable, but I will have to test. I just uploaded the default design version. I will see about a 3MF of the scaled version.
Current version: than.gs/m/1231772 (scaled version will land here if it works)
Why the prusa? You have a 500x500 rat rig 4 idex that you never use and don't show? Why wouldn't you use that?
It isn’t IDEX yet nor fully tuned in yet. Also sure I could print bigger panels on that but far fewer folks have a machine that big. Folks may not have an XL but a 400mm machine isn’t as uncommon. I knew I wanted to release this design so folks could make them too.
I get the whole youtube studio esthetics but to have looks be a main goal or as much of a goal as working seems odd because regardless you compromise function for form
Great idea
You should take a look at the Box turtle.
Oh I will be. Mostly on the Mandic Labs channel, likely in a stream series or a tech focused video. If I like it I'm sure it will appear in more videos.

probably a dumb question, could the rockwool not be cut on the laser cutter?
It is flame retardent, so it would not be a good time I'd say. It is literally made of lava rock. So unless the laser can cut.. rocks... no. Ha
@@MandicReally i mean hey, if nothing else, thats a quick and easy video for next week ;)
I think im going to do some thing like this but make them look like starship heat tiles
Sounds like we should just be printing cool-shaped frames that you can stretch moving blanket hexagons across, then they would look good, be cheap, and be effective, with, like, *way* less work.
@@ReclaimerTyphoon moving blankets aren’t nearly as effective as the insulation I used. They are just a good stop gap if you cannot afford to build things with better materials. Layering them may help, as it is the depth of the material that is playing a part in the roll. That wall I referenced in the beginning is 6” thick to maximize the insulation material and help improve the effect. A Less than 1/2” thick moving blanket really can’t do the same unless layered over and over and over.
Don't be fooled by the box that I got, that's still that still faster than the bag.
