Instructables user Amandaghassaei has posted a HOWTO for making a 3D printed record that plays on a regular turntable. Her method converts any digital audio file to grooves ready to print. It's a bit fuzzy, but still rather exciting! I'm waiting for the way when taking a snapshot of a vinyl disc can be the first step toward deriving its audio content, converting that back to a shapefile, and printing out a high-fidelity duplicate.
In this Instructable, I'll demonstrate how I developed a workflow that can convert any audio file, of virtually any format, into a 3D model of a record. This is far too complex a task to perform with traditional drafting-style CAD techniques, so I wrote an program to do this conversion automatically. It works by importing raw audio data, performing some calculations to generate the geometry of a record, and eventually exporting this geometry straight to the STL file format (used by all 3D printers). Most of the heavy lifting is done by Processing, an open source environment that's often used for coding interactive graphics applications. To get Processing to export to STL, I used the ModelBuilder Library written by Marius Watz (if you are into Arduino/Processing and 3D printing I highly recommend checking this out, it works great).
I've uploaded some of my complete record models to the 123D gallery as well as the Pirate Bay. Check Step 6 for a complete listing of what's there and what I plan on posting. Alternatively, you can go to Step 7 to download my code and learn how to make your own printable records from any audio file you like.

McMansion Hell is a hilarious blog where Johns Hopkins Peabody Institute graduate student Kate Wagner posts scorching critiques of the architecture of McMansions — but this week, Wagner announced that she had shut down her blog after spurious legal threats from Zillow, which admits that it doesn’t even hold the copyrights to the images it […]
The Flux chair is a $130, 12lb “origami-style” polypropylene lounge chair designed by Douwe Jacobs; it sets up in minutes and is stable and lovely (there’s also a $65 kids’ version and a whole range of furnishings including a bar, coffee table, countertop, end-table, etc). (via Yanko Design)
The first time Merle Rasmussen played Dungeons & Dragons, he thought it was a Halloween game.
“It was October 1975, and I was an 18-year-old freshman at Iowa State University. My roommate got this game filled with skeletons and undead monsters. I had no idea.” The role-playing bug had bitten him, but fantasy wasn’t his genre. So that same year, he started writing a game set in a modern world, the spy game that would become Top Secret.
Despite the upfront cost, electric toothbrushes are much better at removing plaque than those freebies from the dentist’s office. For those who struggle to fill the American Dental Association’s recommended two minutes of brushing time, or anyone with limited dexterity, a sonic toothbrush can give your oral care routine a boost.To keep your chops healthy […]
Learning a new language will give your resume an upgrade, sure, but it will also provide a huge cognitive boost for mental tasks outside of translation and conversation. Bilingual brains have been shown to be better at handling multiple concurrent tasks, and gaining fluency in a new tongue is an amazing way to improve memory, […]
If you struggle to get a good night’s rest, consider replacing your pillows before dropping hundreds on a new mattress. You can give your tired neck a break with a 2-pack of memory foam pillows, available now in the Boing Boing Store.Each of these pillows is stuffed with cooling polyurethane foam that molds to your […]
