We have covered a number of 3D printing pens in the past. The Lix Pen happens to be the slickest one yet. You can use the Lix to draw and write in the air. That means you can bring your ideas into life faster. The Lix Pen works like 3D printers. It melts and cools plastic to create rigid structures. The pen has a beautiful aluminum body and works with ABS and PLA. The pen is ready to go in 1 minute. This special pen will be on Kickstarter soon.
