Common materials used for 3D printing are nylon fiberglass, durable nylon materials, plaster materials, aluminum materials, titanium alloys, stainless steel, silver plating, gold plating, and rubber-like materials.
Many different technologies exist for 3D printing. They differ in the way the materials are available and are built in different layers to create parts.
The ABS material has become the engineering plastic of choice for 3D printing via fused deposition because of its good hot-melt, impact strength. Currently, ABS is mainly used after being pre-fabricated into filaments and powdered, and its applications cover almost all daily necessities, engineering supplies, and some mechanical supplies.PA is strong and flexible at the same time, so it can be directly utilized for 3D printing to create equipment parts.
Expanded information:
3D printers are equipped with metal, ceramics, plastics, sand, and other different "print materials", is the actual raw materials, the printer and computer connection, through the computer control can be put into the printer. Connected to the computer, the computer control can be "print material" layer by layer superimposed, and ultimately the blueprint on the computer into a physical object.
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 referred to as "printer" is a reference to the technical principles of ordinary printers, because the process of layered processing and inkjet printing is very similar. This printing technology is called 3D stereo printing technology.
