Introducing 3Doodler, a cheaper alternative to the 3d printer. The doodler allows you to paint with your hand, on paper or up in the air, getting genuine 3d sketches like objects or stuff created solely by your imagination.
Instead of ink, the printing pen is fuelled by a plastic colour wire which is heated to the point of melting until right before you start
painting printing. A cold air jet blows through the edge of the pen and solidifies the wire almost instantly. The wire material is pretty flexible, but also durable. Just like some ordinary markers, you can draw with different colors by changing the plastic wire alimentation.
