Full circle, after a fashion.
I read somewhere that theoretically you could reproduce the sounds of Ethiopian 1000 BC village life, by interpreting the “wobbles” on clay pots, thrown on potter’s wheels.
Similar sound-quality to this I imagine… which is similar to the very first wax tumblers. This is off a $250,000 printer though – Objet Connex500… not exactly a hobbyist machine. I’m guessing it will be a year or 5 before sub $2000 can do 600dpi (42 microns xy, 16 z). As far as I’m aware, hobbyist machines are currently clocking in at about 100 microns. I’m not sure if there’s a Moore’s Law attached to printer resolution. I guess there is. 5 Years then. The “it will happen, but I don’t know when” event-horizon.
So there you go – the world’s least efficient digital to analogue converter.
