Amanda Ghassaei has created a detailed tutorial on Instructables on how she made a 3D printed record using converted digital music files. The audio on the record is very low resolution but it actually plays on a standard turntable.

In an effort to boldly 3D print where no man or woman has 3D printed before, I’ve created a technique for converting digital audio files into 3D printable 33rpm records and printed some functional prototypes over the weekend. These records play on regular turntables, with regular needles, at regular speeds, just like any vinyl record.
