Big Thanks Tom for checking FD52 out! Anyone who wants to ask me anything about it, give feedback etc feel free to contact me. Im not stopping development to keep pushing the potential of 3D printed drivers :)
this is amazing! respect.
The FD52 plus the minidsp created an impressive result!
Great work Paul!
It's a really fun project! As I mentioned in another comment, I've been experimenting with 3D printed drivers on and off for quite a while. Got a few that actually played and made sound, but nothing this good!
I think I need to get my hands on some softer TPU.
Also... do you know how hard it is to search for "3D printed speaker"? All you get is enclosures. LOL Even searching for printed drivers didn't get me much that was on this level.
Ain't that the truth..... accidentally stumbled across paul by mistake when trying to see if anyone actually had done a.passive radiator
"The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak. In the event that the Weighted Companion Cube does speak, the Enrichment Center urges you to disregard its advice."
You know what to do Tom...
This was a triumph...
wow very well done!! that encloser looks amazing!
That's pretty crazy, also including the amount quality you can gain with the DSP
DSPs are SO GOOD
@@MadeWithLayers Could you drop some details about your DSP setup?
For real... just look at Bose! Their speakers are .... kinda not great on their own. They lean almost completely on DSP for their design.
Could you do the DSP stuff on a raspberry PI zero?
@@BRUXXUS Construction wise their speakers are crap. But they have some of the best DSP technicians and they were one of the first mfg who started that DSP thing. A DSP makes the speaker quite inefficient but at low volumes it doesn't matter at all :D
That sounded SO much better than I imagined it would after you tuned it. I thought this is going to be a proof-of-concept. But this sounds like something that is actually usable.
i dont think so, i think it would sound like absolute garbage irl. its a fun proof of concept, but we have to take current portable speaker quality into equation. but as an exercise its super interesting. also that an obscene amount of glue...
It actually does sound pretty good! Like I said, definitely comparable with a small speaker and very impressive for a fully 3D printed unit!
FD51 was built into my twin vented cabinet and run for multiple months in a warehouse as a test and did alright. Now I am working on scaling to larger and more capable drivers
I've been 3d printing speakers too on my Ender 3 using PLA and TPU filaments, printing everything except the wire and the magnet. And after 5 versions it actually sounds great!
I have printed a set of polymates tenacious 6 speaker drivers and enclosures and I am blown away by the way they sound. Sure, they don't beat my Infinity floor standers but for a pair of speakers with 6cm drivers made on a home built 3d printer it insane.
this is a massive leap forward for home manufacturing
Will keep trying in my little niche. I hope to see many more!
Imagine having the ability to print replacement parts for a car speaker! The idea of being able to do something like that is still a bit mind-boggling, yet super amazing!
@@kingsummit5310 Stay tuned! I have something around this in the pipeline for a youtube video ;)
Need to get cheap and reliable multi material printers so less end assembly is needed.
Pretty sound idea
It really is impressive what printing can do for the home hobbyist.
As an audio engineer and musician I have to say...that's not bad!! Way better than I expected.
Simple suggestion: wind the coil tighter it will make a big difference. Maybe build a jig to chuck the coil in a drill; I've built electromagnets this way at work and while it's not as good as a real coil winder (I've done that too) still better than by hand.
Thanks, I'll try that for the next build!
Someone's been playing Portal :)
Very nice!
I really want more details on the tuning and DSP stuff you did. It was pretty incredible hearing the difference in sound after you tuned it!
What, no conductive filament coil? :D
When i first heard about conductive filaments I was all excited.... then I saw how "conductive" they are and I was sad.
@@someguy2741 Exactly this issue. I even attempted printing the VC copper wire into the filament but proved very tricky!
@@Polymate3D I think the coil is a lost cause... for wiring in general I think I am going to try making 3mm tunnels in my next print. Then I can either have a pause and lay in the wire with a dab of hot glue or leave the channel and then push a wire in from one end. It would make super sleek wiring especially in short runs. Just need to have decent radius turns. Lol... I cant remember if you did this... I am going to watch it again... this time not at work ;)
I’ve done magnets like yah before, but never would’ve thought of wiring, great idea:)
After this video I started looking at my own speaker designs and seeing whether a passive would work. For some of my nd65 and 68 projects, or the little 3" tang band subs even, a printed passive would be absolutely perfect. Going to work on it tonight with the new artillery x2
love the project! :)
oh youre here? cool.
Wow, I'm surprised how good that sounds! Great project, great analysis of the EQ and tuning. Wow.
if you connect the coil terminals directly to a fixed point, they will break from vibration. Factory speakers therefore use a braided stocking made of very thin wires.
Tinsel wires would be a nice extra that some later designs may need to implement. In these designed the driver moves at best +/-2mm and the wire is 0.17mm so rather thin. Testing of previous drivers with 200+ hours use have shown zero issue, but as it becomes thicker and more movement, 100% agree :)
What a great proof of concept! I am totally inspired. Been wanting to experiment with "field coil" speakers (no permanent magnets, uses an energized coil concentric to the voice coil) and this proves it's not that hard! The ability to print the spider and surround in flexible TPU is incredible. Yes, yes, yes. I've got a CNC coil winding machine and should be able to make an efficient speaker motor. I'm thinking of experimenting with vacuum forming the cone from a 3d printed mold.
Interesting topic, but I feel like this video only scratched the surface despite its length: why are the magnets arranged like that (e.g. at 2:10 repelling each other?)? Why are there washers in between? What are the washers on the outside (2:40) doing? Where is the magnet wire fed through, how is it strain-relieved (so it can't pull on the cone)? What DSP are you using, how did you set it up?
So many questions, such montage, few answers ;)
The best test for speaker sound quality is to play white noise with the calibration microphone about an inch away from the driver pointed at the center. Better if you can record it in a foam box to completely deaden everything.
You then open up the recording of white noise into a DAW with a frequency analyzer. That should give you a very good estimate as to how the speaker would sound like as opposed to listening to how it sounds like through a video.
Super awesome project Tom! Really shows what 3D printing is capable of and also the creativity of people.
Tom this is the stuff I love the most, carry on and thank you! Well done Tom and well done Polymate 3D!
Now play "Still alive" from Portal on it. 😁
The speaker and enclosure is interesting, but you've Nerd Sniped me on the USB-programmable DSP. You're going to have to drop a video about that DSP now! :)
Ik think it's a Wondom JAB series amplifier. I'm also very interested how to build a speaker with this amplifier and tune the dsp. They also have battery boards so you can make your own bluetooth speaker.
Wondom sounds Chinese,.which it is but it's also the same as Sure as far as I can tell which is a pretty big name in audio
he uses sigma studio for tuning and board looks like adau1701 dev kit
Holy cow... These sound better than I EVER expected them to. One day one will be able to craft a pair of studio monitors at home... If by then they aren't able to just go ahead and print it in one shot haha. This is pushing the boundaries just like those other crazy print tests. Well done.
Very cool project, Props to the designer!
Lol.... Very impressed. Heaps of your viewers have asked about the DSP. A good opportunity for another video. Great work!
More great content. Really great to showcase trends around the 3d Printing space. Very hard to keep abreast of all the great things people are doing.
Not bad at all was abit worried it would sound tinny and harsh but pretty much the clarity was there i'm impressed well done Tom
Naturally, I see this video while I'm out of town (for work) and constrained to laptop speakers. I'll have to watch this again when I get home. What little I could tell, that's a shockingly good acoustic reproduction for something that was mostly plastic filament mere hours earlier. Amazing.
Wow this actually sounds way better than I expected. Crazy what 3d printing is capable of :D
I like the heavy duty super-colliding super button platform too!
Me, not needing speakers for anything. After watching this: "Must buy more TPU!"
Really awesome project! Good value too, *IF* you already have the filaments. If you need to buy 2-3 different rolls of filament you otherwise don't need, and especially if your printer isn't rigged for flexibles already, then the value aspect goes out the 5th floor window. But that's the reality of a very large portion of _most_ projects. IMO it's more of a learning and mastering type of deal, than bottom line value thing. And that's absolutely fine as long as you go in understanding and accepting that, as with most other hobbies and learning opportunities :)
Agreed. For many the concern is purchasing a whole real of TPU. Luckily you can get samples of 5M to 20M fairly easily. A FD52 driver uses approximately 3M of TPU for each one, so a 10M or 20M sample will do the job for that. FD52 also uses PETG for the chassis and cone, as does some of my other designs, and I have also done FD51-4OS which was done with PLA. A lot of these early designs where focus around as easy a entry point as possible :)
Very cool! This is the kind of thing that makes 3D printing so much fun.
Great video Thomas, and your print looks great
Super cool video! I had a thought, during the longer time lapse sections (like the beginning putting it together) it'd be cool to have something like text overlay with a short explanation of what the different steps are for/accomplish.
Entertainingly, I got a markforged ad halfway through one of the sound tests which had almost identical music to the ad, so I hardly noticed the ad starting!
This is a very nice print, I have never thought about doing something like this!
Awesome as always!
After the voice coil wires break because they were single strand, replace the moving speakers with braided wire. You can use desoldering wire or get some from a headphoone cable...
This was a concern of my own, along with other things so a pair of Tenacious 6 drivers were put in a car for an entire year, traveling 6,000 miles and used at volumes including use on the motorway. 0.17mm wire had is issues due to the limited 3mm one way travel. Longer throw drivers for sure you be better to go tinsel wire. Hope the insight helps - Paul
Tom is always an expert, I couldn't believe it her used call on the box 👍
As someone who has built many a diy speakers over the years. This is pretty cool. I will have to try and diy something with my own 3d printers. Your frequency response sounds are so familiar to me. Though a lot of the audio testing jargon will be most people won't understand what you are talking about. Though I'm old school and would have built a cross network
This is very cool! I am currently designing my own 3D printed modular speaker system that allows you to quickly swap out different pitch speakers to get the sound you want. It uses commercially available drivers but I might try out a 3D printed one to find out how well it works. Thanks for showing this cool project off! 💙💜
Paul hitting the big time! I think I was his first Patreon supporter!
Thanks for all your support getting it out there. Amazing how far things have developed in a year. No plans on slowing down either :)
thank you for making videos it's allways a pleasure to watch em and lern stuff!
I would love a video about the audio processing and calibration stuff you did to the speaker!
AWESOME video of a practical 3D printing project!
as a sound nerd do you have that DSP setup somewhere? like a build video for all the hardware you are using?
Totally got to second this - very curious!
I see you used washers for the iron chore.. I liked this idea, Been having rough challenge to rebuilding a disk cutter for my own use. with little to know help. i typed in 3d printed speaker and your video popped up. So glad i though of this. Great video. Its still a challenge to drive speakers, i have tried nuts and bolts. and Doing it old school with Bottle caps and stuff. As i dont have a 3d printer..
Nice Paul ! cool to see your design here !!
Great video Thomas.
I wonder though if the complexity of that enclosure was necessary. (I know it's not your design) the best case scenario for a speaker box is as rigid as you can get it.
Hmmm. It seems like it could be a good solution for an outdoor speaker that can be left outside, if printed in petg rather than pla for the hard parts, not sure how tpu will stand up to uv exposure though.
Not quite outside, but watch this space. I have a plan around testing printed drivers in more harsh enviroments than the home :)
@@Polymate3D look forward to seeing it.
I'd like to see some DSP-Tutorial or a Link :P
Wow amazing. I'd be curious if this could be done as a more flat panel speaker?
I'd like a small portable boombox that is powered by a raspberry PI zero or similar.
Also was confused by "passive radio" but it's a passive radiator.
Wow, that processing makes a huuuge difference! Cool project my dude
This is straight to the point
3D printing drivers? I never saw that coming, mindblowing!
Which dsp unit did you use? Seemed really effective!
I know, right? Weird that it's one of the few things he left out when it features so prominently in making the speaker sound decent. Would love to see a video on just setting up the EQ/filters.
I want a whole video on that DSP process!
Might be SigmaStudio from Analog Devices possibly.
It's a fully programmable ADAU1701 - you can get the boards for about $15 from Aliexpress (you need an USBi to program it, though - there are DIY versions of that). Many "DSP" boards you'll see are nothing more than simple EQs, this does so much more.
The graphical programming is done in SigmaStudio, which is free.
@@MadeWithLayers Thank you! I assume you need a half decent mic as well. ?.?
Pretty amazing Thomas! Thanks for the video
Awesome job Thomas!
It's awesome you also know about acoustics and DSP, plenty enough for this project.
In the sound demo it seemed that the low-end was not super clean, it might be worth checking again distortion levels and rub&buzz and boost more selectively the low end.
You didn't share too much details about which DSP board you're using tho, I'll look in your previous videos.
Nowadays there's a few Raspberry Pi sound cards with Sigma DSP built-in and remain affordable, I wonder it if was one of them.
Ooh, those sound cards sound interesting! Do you happen to know what they're called?
The DSP I used is a simple ADAU1701, which you can get on the little board I show for about $15. May need to do a separate video on it!
Wow that is very impressive buddy amazing job looks too and fully Functionable 🙌🏼🔥👍🏼
I've been wanting to try a passive with a commercial driver for a while... now I can try the link
Cheers
Cool video man! Totally didn't expect your music taste, but I like it! Also, where did you get that vest? It looks super comfy
I love this kind of stuff when I think about expanding the footprint of mankind in sustainable colonies. A Martian colony isn't going to have a speaker manufacturing facility - but they WILL have 3D printers, magnet wire, and some epoxy.
This was something I was thinking off the other day haha. I will keep improving my designs and you never know. I think there is potential to 3D print many practical parts instead of mass production for this exact purpose!
Great Projekt! Zuschauen Hat mega Spaß gemacht !
You beat me to it, I was working on printing a 6.5 in sub woofer. Having trouble with finding a slicer that lets me print circles in actual circles and not lines so my spiders and surround are more structurally accurate. Nice job.
Actually there’s a solution for that! There’s a post processor called Arc Welder that will take the gcode your slicer makes and replace curves made of many small lines into actual arc commands. Just have to make sure you have arc support enabled in Marlin (may be on by default or may need to recompile, but it’s just a single flag if you need to). Google Hackaday Arc Welder for a good overview article. I think there’s even a post processing plugin for Cura so so it right at export, otherwise you just manually process your exported gcode.
So. Much. Woah! This changes the game! I also had no idea what a DSP was.
What is the DSP hardware and software used?
would it make sense to use flexible filament like tpu? You could not only use it as an membrane but also as a sealing solution!
What DSP are you using Tom?
Great build montage. Reminds me of the A-Team.
Did you try filling the housing up with a mixture of plaster and glue to make it sound less tinny ?
I missed something here, and the description. How does the driver even work? I was unaware there was anything else even as close to usable as the common moving-coil in a magnetic circuit gap.
Oh wow
Thanks for the video.
Love the textures filament
Heh. I love it. With the DSP and inexpensive parts, you basically made a Bose speaker. lol I'll appreciate any speaker related projects you make.
This is genius Tom
You are crazy! I LOVE this project!
Print conductive layers and you could also make the voice coil
The only thing left would be managing to print the copper coil with conductive filament & duel extruder or auto wire imbedder.
i figured if elegoo neptune 2 was sponsoring the video, they'd be dropping a batch on amazon. they did!
You know that @3dprintingnerd is going to have to make this thing at 300% scale now! Please Joel do it for the high five!
This video is brought to you by the Elegoo Neptune 2...
Might as well have been Godzilla, Big Foot, Chupacabra, Banksy, Atomic Science...
And anything else I'll never see with my own eyes!
Thomas, would it be possible for you to tell a little bit more about the sound source you are using? DSP, amplifier etc
Been waiting for this video after the teaser on Twitter!
Shame you can't double like :O)
Just finishing off printing some speaker enclosures too. Have designed speaker drivers previously - but never 3D printed them. Obviously easier to outsource. But that's clearly far from the point here. Hats off - excellent build!
Thanks Phillip. I am continuing to work hard on this, and any feedback on design & assembly is greatly appreciated, along with any documentation I can read!
Hi Thomas, great work! What kind of DSP setup are you using ? I’m fiddling with a hifiberry dac and a raspberry pi, but I’m not sure how to create a customise an eq to match the speaker built
Very impressive! It sounds great, and I learned some things about speaker design in your video. Also, the colors remind me a lot of the Half Life inspired SA Carbon and GMK Carbon keyboard keycap color scheme.
I wonder if you could print conductive resin coils??
wow this is amazing
@Thomas Sanlader can you make a video for how to make and use the DSP i want to use cheap sub driver for mid-range put voice sound a bit muffle
I’d expect deformation on the coil on a bigger speaker with more heat probably best for small scale
As you go bigger, thermals do become a concern for sure. In my biggest motor since this, it has much more metal mass for heat dissipation and much more efficient motor, reducing the heat output. Highest power output so far on a 25mm voice coil was 20W. This will be explored further! - Paul
Important question would it be much better in quality of sound if it was scaled like 200%?
Is it my headphone or your speaker actually sounds so good? Joke aside, damn inspiring Tom, every real-life-aliek project of you.
It does actually sound pretty decent!
Would it be possible to use conductive and magnetic filament to make a _fully_ printed speaker? The quality would probably be terrible
My initial feeling is that just because you CAN print anything, doesn’t mean you SHOULD :) I can buy a really nice 2-3in driver for ~$10 with known sonic characteristics that you can use to make a cabinet to give you decent sounds.
For a fun project, I think this is great, but won’t be swapping out my drivers any time soon.
Cool design, though. Good job
That is greatly impressive. What kind of mic is that?
Now I want to know how you do all that EQ software magic.
