3D printers is a type of industrial robots. The most prominent advantage is that digital models could be designed directly from the computer without machining or any molds. These digital models could be parts of any shape. Thus, greatly shortening the product development cycle.
It common uses to making mold or doll. It also had brought great breakthroughs to the development of technology. For example, 3D printing technology could help manufacture large and small parts required by the industry, which is faster and more accurate than traditional parts.
