LIX 3D Pen

The smallest and smartest 3D printing pen in the world! Enables you to doodle in the air.
 If you've ever wanted to see your notebook doodles and 3-D designs to come to life, you might be in luck.

Meet Lix, "the smallest pen that does not require paper." The 3-D printing pen, created by a London-based company, allows you to doodle mid-air as plastic filament melts and hardens into a freestanding shape.

All you have to do is plug it into a USB port, and the pen takes less than a minute to heat up and be ready for doodling.
