3D printers have already been gaining mass popularity over the past few years, and now here we have a 3D printing pen, the 3Doodler.
Allowing users to draw anything they like without the aid of a computer or software, the pen uses the concept as 3D printing, heating and cooling plastic as it passes through the body of the pen, allowing the user to create limitless design possibilities.
Take a look at the video below to see the pen in action, and check out their Kickstarter page.
