If you don’t mind ending up with oddly shaped 3D printed parts you can get your printer to sing to you. The display shown above is doing just that. The Lulzbot is being driven particularly to create a specific frequency of noise with its stepper motors. The results of a few different tunes are what’s hanging on the wall to the right. You can hear it printing Bizet’s Carmen in the clip after the break.
[Rickard Dahlstrand] hacked together a Python script capable of parsing a MIDI data as well as outputting a G-code equivalent that will create the frequencies as well as durations necessary to hear the audio on a stepper motor. As we mentioned, he utilizes a Lulzbot however the script appears to include setting for Cupcake, Thingomatic, Shapercube, as well as Ultimaker. The parser script in addition to the example G-code data for a library of classic music can be downloaded from his repository.
Now if you’re looking for some other crazy CNC music concepts you can’t beat this wineglass music hack.
