Lake Area Technical Institute student Austin Dutenhoeffer is using his 3D printer to make music. He does this by taking MIDI files of songs and converting them into G-Code. That code tells the 3D printer's motors how to move and different movements have different pitches. It is uncannily accurate, although it does lack some of the emotion. He has uploaded these files to Thingiverse so that anyone can have their 3D printers making music in no time. Check them out at 3DPrint.com: http://3dprint.com/97111/3d-printer-music-to-your-ears/
