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 ProcessingHave 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 justdownload the vector of it for your 3D printer.

“Friendship bear and chimpanzee ~ Unexpected friendships have a couple of guests Zoo Myrtle Beach Safari park, South Carolina, USA. The five-month grizzly bear named Bam Bam and chimpanzees Wali play and grow up together, enthralling visitors to the park. As soon as the friends grow up, they will go into the natural habitat: Bam Bam in North America, and the Wali in the jungle of southern Africa. Photos by Barry Bland/Rex Features
