Although using a new technology to create an obsolete technology that plays another new technology might seem counter-intuitive to some, it certainly isn’t the case with Instructables’ assistant tech editor Amanda Ghassaei who has created the world’s first 3D-printed records.
Ghassaei used a highly advanced 600dpi 3D printer to create multiple sheets of plastic no thicker than 16 microns, thus replicating the grooves we associate with real vinyl records. The sampling rate and resolution are considerably lower than those of real MP3s, but the records can be played back using a standard needle. Despite the resulting poor audio quality, the successful production of these records represents just one of the many yet undiscovered ways 3D printing technology can be used.
