There are many different technologies for 3D printing. The difference between them is that components are created in different layers in the form of usable materials.
Because of its good hot melt and impact strength, ABS material has become the first choice for melt deposition of 3D printing engineering plastics. At present, ABS is mainly prefabricated into silk and crushed for use, and its application scope covers almost all daily necessities, engineering supplies and some mechanical supplies. PA has high strength and flexibility, and can directly use 3D printing to manufacture equipment parts.
Extended data:
3D printers are filled with different "printing materials" such as metal, ceramics, plastics and sand, which are real raw materials. After the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer becomes a physical object.
Generally speaking, a 3D printer is a device that can "print" real 3D objects, such as robots, toy cars, various models and even food. The reason why it is popularly called "printer" refers to the technical principle of ordinary printers, because the process of layered processing is very similar to inkjet printing. This printing technology is called 3D stereoscopic printing technology.
