3Doodler: 3D Printing Pen Turns Sketches Into Reality.
Twenty years ago it would have been impossible to imagine that one can sketch 3d models right into space. Now however this idea is very plausible with the aid of the 3Doodler; a pen-like device which “extrudes heated plastic, which quickly cools and solidifies into a strong stable structure.
This allows you to build an infinite variety of shapes and items with ease! Most people will instantly be able to trace objects on paper, and after only a few hours of practice you will be able to make far more intricate objects.”
