USD $ @ 3Doodle
The 3Doodle starts out like any other kind of pen, you begin by drawing normally, with the nib pressed to paper, but then you lift it in the air and the pen keeps drawing.
The plastic hardens almost immediately, cooled down by a teensy fan contained in the nib of the pen.
The 3Doodle is incredibly cool but it offers more than just novelty. According to the company it can be used to create jewelry, pendants, fridge magnets and allows users to personalise things like smartphone cases, laptops and tablets. It also creates the potential for designers to literally draw a prototype of their idea, allowing them to map it in 3D before it has even gone into production.
