3D printing records

This Instructables shows how to 3D print a record. The quality does not match a commercial vinyl disc, but the precision is high enough for the song to be recognised. We already knew how to pirate a vinyl record to make a copy, but you need an original, whereas the printing technique does not.

If you’re interested in knowing how vinyl records were (and still are) made, check out this video.
