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)

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.

Step 2: 3D Print the Parts

We printed them at 100 microns. Remove the top part of the speaker from the printing base very carefully since the membrane itself is just 0.1mm thin! Wash the part in alchool and post proccess it putting it next to an UV lamp or under the sun for 5-10 minutes.

Step 3: Coil Winding

Use the enameled copper wire to make the coil. 10 to 20 revolutions should be enough, depending on the thickness of the wire. A small drop of the same resin used to printing the parts can be applied to the coil to glue it to the speaker.
