Like the MakerBot Thing-O-Matic or the Solidoodle, The Cube by Cubify lets you design a small object with with a Mac or Windows computer, and then "print it" with extruded plastic. About the size of a large upright sewing machine, and weighing 9 pounds, the printer is portable. Plastic is supplied by special cartridges (called "The EZ Load cartridge") sold at $50 each, which provides enough material for about 15 products. The plastic is available in multiple colors. These are one-color, single head printers -- in other words projects can only be one color, and creating a project takes a lot of time. The cube has internal Wi-Fi, so it can be synced to your home Wi-Fi router. Visit http://www.printin3D.com .
