3D Printers Can Produce Records

The needle drops and a series of high, repetitive whines come from the album. Then a crackling sound, and a muffled guitar riff. Finally, Kurt Cobain's voice — audible, but distant and hollow, like he is singing in a tunnel with a scarf over his mouth.

It's about the worst version of "Smells Like Teen Spirit" you could find. But it is awesome all the same for its totally unique medium. This particular LP is part of the batch of the first records ever to be created on a 3-D printer.

"It's surprising how much you can deform and down-sample an audio file and still recognize it," says Amanda Ghassaei, assistant tech editor at Instructables, who printed the record, and several others, including music from the Pixies, Daft Punk, and Radiohead.
