3D printing technology, as one of the cutting-edge industrialization technologies, has the following advantages:

(1) Achieve high precision and adapt to highly complex manufacturing through digital means;

(2) Reduce the mold processing production link, compared with the traditional machine tool processing more quickly and directly, and save materials;

(3) Be able to directly print finished products, greatly reducing the cost of product assembly. At the same time, due to the limited size of the equipment or the limited types of materials, the application is limited; 

The types of materials suitable for 3D printing are limited, including engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials; The finished product is often composed of parts of different materials, and even some parts are composite of a variety of materials, 3D printing of a single material can only provide parts, can not generate finished products, you can use the prefabricated method to assemble various 3D printed parts finished products.

3D printing technology is one of the cutting-edge technologies of industrialization, which can coordinate or promote the development of some technologies, or even replace them, but it is impossible to replace all the technologies of industrialization. 3D printing technology can continue to be researched and developed for large-scale printing, the development of new materials suitable for various needs, and composite/combination printing methods.
