3D printing technology has appeared in the last 80 to 90 s of the last century (also known as rapid prototyping technology), which has been a time of less than 30 years to date. The principle is very simple: a technique of constructing an object by printing layer by layer using a bondable material such as powdered metal or plastic as an input from a 3D digital model file. Vividly, a common printer outputs a 2D image or a graphic digital file onto paper through ink; the 3D printer outputs actual raw materials (such as metal, ceramic, plastic, sand, etc.) into a thin layer (having a certain thickness physically), and then the thin layer is repeatedly stacked one on another, so as to finally become a space object. Thus, 3D printing is similar to inkjet printing in that it outputs a certain layer. Like a house, is built up from one brick, while 3D printed items are built up from one piece of raw material. Since 3D printing is the stacking of materials one on top of the other, it is also referred to as an additive manufacturing process. 3D printing is not mysterious, and compared with an equal material manufacturing process with millennium and a material reducing manufacturing process with hundred years, the 3D printing is only a new manufacturing and forming process, and has a history of less than 30 years.
