Hero Forge is like an RPG character creation tool. You choose a gender, choose a build, choose some armour and get yourself a reasonably unique character. Only at the end of this one, your character gets made in the real world instead of being trapped inside a video game.
Designed with tabletop gaming in mind, Hero Forge is a Kickstarter campaign with two components. The first is the creation suite, where you design your characters online. The other part is a 3D printing service that actually builds the things.
The detail they're getting, even on small 30mm pieces, is pretty damn good, though you can also get larger 6-inch pieces that are obviously way cooler.
Sadly, 3D printers aren't quite magic enough (yet) to paint the models, but what would tabletop gaming be without having to paint stuff yourself?
There are advantages to this that go beyond just the novelty; most miniatures are made using injection molding, which limits the kinds of designs and poses available. 3D printing doesn't have those restrictions, so you can get character designs way more out there than you'd get from traditional manufacturers.
