3d printers are fully in the public realm now. There isn’t one in every household, but an early adopter can get one of the better “starter” 3d printers for under $2500. The specific 3d printer in the following story is about $250,000, but nonetheless the product is pretty cool.
Amanda Ghassaei at instructables recently developed a routine using processing to convert mp3 audio data into designs for a 3d printer. They’re playable and the songs recognizable. The records have a sampling rate of about 11kHz and 5 bit resolution. A typical mp3 is sampled at a rate of 44kHz and 16bits – roughly 2000 times more data, 4 times more frequent per second.
Watch how its done:
