CAD, Print, Listen - GrabCAD news

One of the most remarkable developments in the past year that we've noticed is the explosive growth in 3D printed music or musical instruments. For years Guitars and other wooden instruments have been carved by CNC machines, directed by CAD models. But now, a few intrepid programmers have begun to create scripts that will generate your very own printable vinyl records! Amanda Ghassaei developed a program to take ordinary audio files and covert the waveforms into the sort of grooves a record player needle needs. "The audio on the records is very low resolution, it has a sampling rate of 11kHz (a quarter of typical mp3 audio) and 5-6bit resolution (less than one thousandth of the resolution of typical 16 bit audio), but the result is easily recognizable." For the GrabCADr with a certain amount of flair, it might be possible to design a unique, 3D design to fit in the centre of the record, where the label sits.... although it ruins the possibility of having a Side B.
