The smart 3D printing pen enables everyone with an imagination to sketch, doodle, and draw objects in air. But it has also its limitations. It produces crude and wobbly lines, the prints is low-resolution, and you won't think it is a tool that has many practical applications.

It only took Matt about 2.5 hours to build a quadcopter with a 3D Airpen. The results are impressive. Check out the video below:
