How to make 3D printed earbuds

How to make 3D printed earbuds that perfectly fit into your ears like singers on stage with their custom in-ear monitors (IEMs).

For starters I would suggest Anycubic I3 MEGAFDM (Fused deposition modeling) 3D printer

Anycubic I3 MEGA ‘s quick specs

3D printed wired earbuds

If you’ve adready have wired earbuds – it’s simple.

If not – you have to prepare the hardward drivers, cable and jack.

Prepare STL (Stereolithography) of your ears’ scanning. Or you can download the STL design on Thingiverse or CGTrader.

Import the STL to the software running the 3D-printer 

Polish the housing – the surface of 3D-printer earbuds isn’t great you either have to coat it with nano coating or paint them lacquer.

Resembling is related to soldering the wire to driver and enclose the housing.

Much simplier for 3D printed Bluetooth earbuds and 3D printed true wireless earbuds.

If you are serious about making 3d-printed earbuds. You have to set up a more complicated project including – scanning your ears – processing, modeling and 3d-printing molds – casting eartips.

You can open a business if you purchase the Formlab form 3

Min layer hight is 25 microns – the 3d-printed object will have a more refined surface
  • Layer height: 25 – 300μm
  • XY Resolution: 25μm
  • Laser Power: 250mW
  • Build Volume: 14.5 × 14.5 × 18.5cm

Formlab cooporates with 3Shape for the modeling your in ears.

How it works?

First your ears will be scanned with 3Shape TRIOS Scanner.

You get the a model – mold of your ears ready for 3D-printing. The mold have to fit your earbuds (or hearing aids) and your ears.

The molds then are washed and dried.

The molds are injected with biocompatible silicone – let them settle for a while in water bath (50 – 60 degrees celsius, in 1 hour).

The custom eartips are washed and dried and ready for use with your earbuds.
