Ghassaei doesn't think the technique will ever be able to replicate true vinyl sound. Right now the 11 Khz sampling rate is roughly a quarter of what you get from the .mp3 that you're converting, and even at higher resolutions--which will produce better sound--it would be difficult to achieve the exact same sound. But that's not really the point. The point is that vinyl is old, and 3-D printing is new and combined they are very cool and interesting. And you can do it at home, if you have access to the right 3-D printing setup. Learn more about that at Instructables.
