Lix reveals a portable, pro-grade 3D printing pen

There's little doubt that 3Doodler's 3D printing pen is fun, but it's not strictly a precision tool; it's big, and mid-air drawing can get messy. Lix believes that pros need something more accurate, so it's crowdfunding a 3D pen of its own. The printer is about as slim and comfortable as a technical pen, giving it the kind of accuracy you'd need for air-drawn artwork and even some prototyping for architecture and fashion.
