Yesterday I sat in for Howard at a demo of the Ditto Pro 3D Printer
by its makers, a Vancouver-based company called Tinkerine. Over the course of my half-hour session the printer, maybe a little wider than a large coffee maker, chugged away in the background, slowly but surely squeezing out tiny layers of filament in what would eventually become a souvenir that I could take home—a replacement knob for a stove top.
If that sounds a tad unimpressive, it shouldn't. This piece was made in less than half an hour using a spool of biodegradable corn starch, on a machine that retails for less than $2,000 USD. And you can use it with your phone.
