Amanda Ghassaei, an Instructables contributor, was struck by curiosity about the capability of current 3D printing technology. Turning to the latest and greatest in 3D printing, the Stratasys Objet Connex500, she was able to take a digital audio file and convert it into a playable 3D model of a record. But even at "600dpi in the x and y axes and 16 microns in the z axis" resolution, the resulting audio quality sounds like an audio tape recording of a record played through AM radio at low volume with a bad case of tinnitus. Nevertheless the experiment is an exciting hint about what's possibly in store for tech-loving vinyl fetishists out there, and Amanda's explanation of the project should hopefully inspire others to further improve the technique.
In the spirit of Instructables open source model, Amanda was kind enough to share her Processing code, 3D model downloads, photos, and an incredibly detailed record (pardon the pun) of the whole process over at Instructables here.
