Amanda Ghassaei has created a technique for converting digital audio files to 3D-printable, 33rpm records. Ghassaei wrote a custom program to do the 3D modeling and then used a Objet Connex 500 printer to print the records.
The audio quality is low—the records have a sampling rate of 11kHz (a quarter of typical mp3 audio) and 5-6 bit resolution (less than one thousandth of typical 16 bit resolution)—but the songs are still easily recognizable…check out the video below:
The tracks sound muddy at best but nevertheless the project is an impressive achievement, yet another milestone in the unfolding saga of 3D printing—and if I do say so myself, a much cheerier one than the recent trend of 3D-printed guns.
Ghassaei goes into full detail about the project from concept to creation at the Instructables website.
