3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that builds objects by layer-by-layer printing based on digital model files and using bondable materials such as powdered metal or plastic. . 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold making, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. Ordinary printers used in daily life can print flat objects designed by computers, and the so-called 3D printers work basically the same as ordinary printers, but the printing materials are slightly different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with metal , ceramics, plastics, sand and other different "printing materials" are real raw materials. After the printer is connected to the computer, the "printing materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer becomes real. In layman's terms, a 3D printer is a device that can "print" real 3D objects, such as printing a robot, printing a toy car, printing various models, and even food. The reason why it is commonly called a "printer" is based on the technical principles of ordinary printers, because the process of layered processing is very similar to inkjet printing. This printing technology is called 9860D stereo printing technology
