The latest in handheld 3D printing, Lix is the smallest 3D printing pen in the world. This device allows you to write and draw in the air, without using paper. Lightweight (around 1.5 ounces) and easy to use, the pen fits the hand more comfortably than other, larger handheld 3D printers, allowing for more intricate details and designs. Even better, the tool can be powered by a wall charger or a USB port. The biggest challenge for the designers has been the reduction of the mechanical parts to fit into the 12mm diameter aluminum tube.
Though it was exceeded the amount of requested funding, Lix still has a Kickstarter campaign in the works, and you can check out even more information on their website. The pen is currently available for $155, including 5 bags of mixed colored plastic. (via colossal)
