From their site:
Thank you for using HERO FORGE®, the internet’s home for customizing and 3D printing tabletop miniatures and statuettes. With the rise of 3D printing, the age of bespoke, made-to-order products is just beginning, and we’re thrilled to be bringing that revolution to the tabletop. Originally funded by Kickstarter, HERO FORGE® is a platform which allows you to create detailed characters in full 3D, right your web browser, with an easy-to-use character customizer. Then, using the power of 3D printing, we’ll turn pixels on-screen into atoms in your hand so you can finally have a tabletop miniature that truly feels like your character.
