Z Corporation develops, manufactures, and markets the world's fastest 3D Printers - machines that produce physical prototypes quickly, easily, and inexpensively from computer-aided design ("CAD") and other digital data. Z Corp.'s 3D Printers are used by companies to make models and prototypes ranging from toys for market feedback to fan blades for functional testing to buildings for architectural reviews. In the same way that conventional desktop printers provide computer users with a paper output of their documents, 3D Printers provide 3D CAD users a physical prototype of real world objects such as mobile phones, skyscrapers, engine manifolds, cars, hotels and even mountain ranges.
