This is a 3D printed Speaker that you can print at home.
All you need is some enameled copper wire and a magnet!

You may have seen 3d printed speaker before, but this one is different since you will be printing all the parts of it, including the membrane itself and it is 0.1mm thick! It is so thin that the black resin we normally use is almost transparent after printing!

This is a good stress test for your printer and I do not recommend trying it on an FDM machine.

A good resin-based 3d printer should handle this.

If you like this instructable you can support me having a look at my IndieGoGo campaign here where you can now get your LumiPocket 3D Printer (that we used to print all the parts in this instructable), it is a project that I started one year ago as a simple hobbyist, and now has became (hopefully) my full time job.

Step 1: Setup and list of materials

  • Magnet, we used a S-20-05-N neodimium magnet, 20mm dia x 5mm height
  • 2x m3 screws and nuts
  • Enameled wire (we scavenged it from an old stepper motor that wasn't working)
  • Parts can be found here: http://www.thingiverse.com/thing:523581
  • Resin-based 3d printer. Parts were printed with LumiPocket 3D Printer (you can get your here, hurry before the campaign ends!)
  • 3D printer Setup: standard or industrial blend FTD resin, 3000 lumens Acer DLP projector, printing time 15 minutes.
What a great idea! I'm going to have to try that out...
<p>trying to print this with a micro 3D to see if its possible.<br></p>
<p>Demo on final step page!</p><p>You can hear some background noise and there is still room for improvement, but we used them connetced directly to headphones jack without external amplification ;)</p>
<p>Hi, A video is on the way as soon as we travel back from WebSummit, Dublin!</p>
<p>great idea! can we hear a demo?</p>
<p>Super cool!</p><p>Video!!</p>
yes, a video of it working of a must!
<p>How well did your speaker work? Was the sound merely noise, or could you listen to music and recognize what it was? Cool project!</p>
<p>It works and you can recognize the music, even without an amplifier, directly connected to the audio jack of a phone or computer. </p>
<p>I think he is just asking for a youtube video to see the speaker working. Strangely he didn't ask you directly for this.</p>
<p>We want a video!</p>
<p>liked</p>
<p>That's an interesting idea. I wonder how well it scales up or down.</p>
