3D-Printed Records Are IRL Versions of MP3s

Using a highly advanced 3D printer with a resolution of 600 dpi, Instructables’ assistant tech editor Amanda Ghassaei creates the world’s first 3D-printed records.

By layering finely printed plastic no more than 16 microns thick, Ghassaei creates the same characteristic grooves a realy vinyl would have. In her Instructables post she provides all the technical mumbo jumbo for any nerds that want to try this at home.

According to Ghassaei the tracks have a sampling rate of “11kHz (only a quarter of typical mp3 audio) and 5-6 bit resolution (mp3 audio is 16-bit)”. The records can even be played using a standard needle, and although they sound absolutely awful, the concept is still pretty cool. Ghassaei’s first experiment? “Debaser”, by the Pixies. ANIMAL approved.
