I thought the idea of printing in 3D was incredible, but now there is a pen which you can draw your own three dimensional sculptures instantly! The 3Doodler is the world's first pen to do this and was created by wobbleworks. The pen uses ABS plastic which is the same material used by many 3D printers. The pen has an inbuilt heater which melts the plastic and it comes out the end like a cake-icer or super glue gun. However the plastic instantly cools and stays suspended in the air where the user had drawn it. Watch their video to see how the pen draws shapes which freeze in the air as if my magic! It looks so fun!
