On Instructables, amandagjassaei shows you how to turn a digital recording of a song into a 3D printed record. The quality leaves a bit to be desired, but still impressive that printing one own's records is possible.

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. Though the audio output from these records has a sampling rate of 11kHz (a quarter of typical mp3 audio) and 5-6bit resolution (mp3 audio is 16 bit), it is still easily recognizable, check out the video above to hear what it sounds like.
