3Doodler

3-D printing has been around for quite some time now, but the 3Doodler is the world’s first 3-D printing pen. This unique gadget makes 3-D printing portable. Created by Peter Dilworth and Maxwell Bogue of WobbleWorks LLC, the 3Doodler uses Poly-Lactic Acid (acrylonitrile butadiene styrene) to create three-dimensional pictures. The pen melts the plastic (available in different colors) and once it is cooled it forms a solid 3-D strucutre.
