Many of us have been waiting for the moment when 3D printers would not only be offered ready-to-use without the need of DIY assembly, but at a price comparable to a common computer. Well get excited, because that day has arrived.

The country is Japan. The company: REAL-f. For a whopping $4,000, REAL-f will use "3-Dimensional Photo Forms" to crank out a crazily detailed replica of your face and turn it into a mask. Because, you know — why not.

3D printers have been getting cheaper and better, but I've never really seen why they'd be useful. But the Origo 3D printer, which is designed to turn kids' drawings into toys, shows the potential that this tech has.

Michael "Skimbal" Curry has honed in on the best use ever for the budding 3D printing technology: recreating Mario Kart's much loved (or hated, depending on what side of the shell you're on) turtley projectile. The Turtle Shell Racers are small, remote controlled and oh my god my fingers don't work anymore I just want one.
