You might have heard about 3D printer but been completely new to its less complicated and more affordable form: 3D pen, or 3D printing pen. In a nutshell, a 3D pen can let you draw objects in the mid-air allowing you to instantly form 3D structures right in front you.

Its working principle is rather simple: when pushing the filament (plastic materials such as PLA, ABS and PCL) into the pen, inside the pen, a heated system can melt the filament and extrudes it through a nozzle at the tip of the pen. Move the pen and you can draw anything you want, not just on ground surface, but in the mid-air. The filament will harden in a few seconds. When you are done, you can pick up the object and hold it in your hands. And for filament, the most commonly used materials are PLA and ABS, the same ones for 3D printers, and there are more options if you want your creation to have the texture of rubber, wood, steel, and marble.

You may wondering what kind of people use 3D pen. Generally, 3D pen is considered an educational toy for children and some brands has designed low temperature pen to better protect kids from burning. Besides this, 3D pen can be a perfect tool in the hand of DIY professionals, artists and even designers for fashion. What you can do with a 3D pen is far more than this, come and get one and draw your own fantasies.
