Three-dimensional printing is a method of printing a virtual 3D model onto a 2-D object. For applying a 2-D image on a 3-D surface see pad printing. 3D printing is a category of rapid prototyping technology. 3D printers typically work by 'printing' successive layers on top of the previous to build up a three dimensional object. 3D printers are generally faster, more affordable and easier to use than other additive fabrication technologies
