"In a collaborative effort between a group University of Tokyo students and architect Kengo Kuma, a unique 3D printing pen that creates freestanding architectural structures has been created.  The handheld printing device &amp;quot;can be used to create complex architectural structures out of plastic sticks.&amp;quot; Each structure is quite durable since the pen fuses each string together using acrylic rods. The pen works in a similar fashion to a gun -- the user applies pressure to a trigger, which allows the rods to be emitted and carefully connected to one another.  This high-tech device will allow designers to drawn their ideas to-scale without using alternative time-consuming materials. The printing pen is described to be able to create &amp;quot;large-scale hand-drawn structures.&amp;quot; This high-tech gadget could be the next best utensil used by architects."^^<http://www.w3.org/2001/XMLSchema#string>
