Radiohead on a WOOD Record by amandaghassaei

In order to explore the current limits of 3D printing technology, I’ve created a technique for converting digital audio files into 3D-printable, 33rpm records and printed a few prototypes that play on ordinary turntables. Though 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)- the audio output is still easily recognizable. These records were printed on an Objet Connex500 resin printer to a precision of 600dpi with 16 micron z axis resolution. The 3D modeling in this project was far too complex for traditional drafting-style CAD techniques, so I wrote an program to do this conversion automatically. It works by importing raw audio data, performing some calculations to generate the geometry of a 12” record, and eventually exporting this geometry straight to a 3D printable file format. Most of the heavy lifting is done by Processing
Have you ever wanted to hear Radiohead on a $3.99 AM only clock radio speaker? well maybe wait around and just buy the wood cut version or just download the vector of it for your 3D printer.
