This project nearly broke me... Building a 1kW Subwoofer from Hempcrete!

Inspired by the design of the SpaceX Dragon capsule, I set out to mold its shape into a highly functional subwoofer, made with eco-friendly materials!

How much did the finished product weigh? I have been a long time fan of your works, please acknowledge me senpai.
You can mix up some plaster as a slurry coat to fill in the any of the surface gaps and imperfections. Plaster is very sand-able and forgiving.
The mold development is what I find most interesting. I'd be fascinated to see your process for determining and creating the mold pieces.
really loving the direction to "use 3d printing for projects" and not just 3d printing!
Am I the only one who was hoping for a flying subwoofer when they clicked on this video?
Shout out to @HexiBase ! Thomas you could have 3d printed the enclosure for a subwoofer!
Every buzz word has been checked and I’m watching.
Cool project idea, but the finish looks like it was made in a non-technical highschool project. Like…really dropped the ball😂
Hmm, space age or stone age? Or some sort of potent fertility symbol?
The no repairability is a killer for me.
Every German's hobby: building speakers.
There's a technique that I remember hearing about for molding stuff like this. You first put on a relatively coat of just plaster on the mold surface, then you let that cure for a bit before adding in the reinforced stuff. it results in a better surface and allows you to make sure you got material everywhere you need it.
Very cool! I personally would've made it easier to fix though, seems more engineering minded that way. :) But unique nonetheless and I like the variety this brings to the channel.
Just want you to know you saved 3D printing for me. I have had an ender 3 for a few years and have never gotten great prints from it. Things have broken and been fixed and I've done a couple upgrades, so it seemed like I was working on the printer every time I used it. Add to that the fact that I don't like running my printer when I'm not home so I'm limited to small parts and the whole experience was pretty frustrating and I ended up rarely ever using my printer. Your video "0.4mm nozzles just became obsolete" convinced me to switch to a 0.6. Suddenly I can print small parts in half an hour or 2 hours. And the print quality looks good!? And I am able to print large parts overnight!? And my direct drive upgrade doesn't jam anymore when printing TPU!? So now I'm selling prints (with the correct licenses I promise) to save up for a bambu with an AMS.
Gorgeous design! Really opens up options for speaker designs
That's an epic build. I think the plaster with all its imperfections looks fantastic.
Arm chairing engineering here but plaster you have to be really cautious on the clean up because already cured plaster acts as a catalyst to speed up plaster curing. so make sure all surfaces that touch the new plaster is super clean.
Looks like a good candidate for aircrete/ cellular concrete. Well done for completing this project, very interesting.
Cool project for sure, but for a better overall appearance, you could have just 3d printed an outer layer and filled using your plaster mix on the inside for the desired density needed.
I'd love a video more about CAD, your work is gorgeous!
