The 3Doodler, the word’s firs 3D printing pen, has already been funded on Kickstarter. From its copy on that site: “It’s a pen that can draw in the air! 3Doodler is the 3D printing pen you can hold in your hand. Lift your imagination off the page! Have you ever just wished you could lift your pen off the paper and see your drawing become a real three dimensional object? Well now you can! 3Doodler is the world’s first and only 3D Printing Pen. Using ABS plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. It’s compact and easy to use, and requires no software or computers. You just plug it into a power socket and can start drawing anything within minutes”
