A viable, efficient 3D printed motor? Yes we can.

This was actually a dream of ours: to design a 3D-printable motor that can be printed on most basic 3D printer models and is powerful and efficient enough for common applications.

The design came from the amazing technical and exploratory mind of our Senior Maker, Christoph Laimer. And it was tricky. You can read all about the foibles of version 0 soon; incredibly valuable trials that led to the successful creation of version 1.

The four elegant components are printed with PTEG, PLA and magnetic PLA, and are paired with a steel shaft, a couple screws and bearings, magnets, and finally copper wire. The result is a relatively small motor (52mm diameter and 54mm length) that boasts 60% efficiency and enough power to run a small- to mid-size RC vehicle.

The makeSEA reference wiki has all the details on Christoph’s 3D printable brushless motor design, including a link to download a makeSEA rights managed version of the STL file.
