For the most part, pen’s require paper---well, consider this the exception.
Lix is a 3D printing pen that let’s you draw and doodle right in mid air. Small in size and extremely portable, the tool functions similarly to 3D printers by quickly melting and cooling colored plastic, letting you design rigid and freestanding structures. Crafted with an aluminum body, all you need to do is plug the power cable into any traditional USB and begin creating.
