This 3D pen lets you draw in the air!
The world's smallest 3D pen can draw solid lines out of thin air. You will soon be able to draw your own physical objects with the help of the Lix 3D
pen. It launched just three days ago on Kickstarter and they have already raised 15 times their funding goal (and it's still growing).
The LIX 3D
printing pen functions similarly to 3D printers. It melts and cools colored plastic, letting you create rigid and freestanding structures. Lix has a hot-end nozzle that is power supplied from a USB 3.0 port. The plastic filament ABS/PLA is introduced into the upper extremity of Lix Pen. The filament goes through a patented mechanism while moving through the pen, finally reaching the hot-end nozzle which melts and cools it down. With this light-weight, engineered pen, these structures can be formed in any imaginable shape.https://www.kickstarter.com/projects/lix3d/lix-the-smallest-3d-printing-pen-in-the-world
