3D printer is no stranger to everyone. Many people must often hear the word even if they have not been in contact with it. So what is 3D printing, what is the principle and characteristics of this printing method? Let's introduce them one by one:
Definition: Generally speaking, a 3D printer is a device that can 'print' real 3D objects, such as printing a robot, printing toy cars, printing various models, and even food. The reason why it is popularly called 'printer' refers to the technical principle of ordinary printer, because the layered processing process is very similar to inkjet printing. This printing technology is called 3D stereo printing technology.
Principle: the working principle of 3D printer is basically the same as that of ordinary printer, but the printing materials are somewhat different. The printing materials of ordinary printer are ink and paper, while 3D printer is equipped with different "printing materials" such as metal, ceramic, plastic and sand, which are real raw materials. After the printer is connected with the computer, Through computer control, the 'printed materials' can be stacked layer by layer, and finally the blueprint on the computer can be turned into a real object.
Features: there are many different technologies for 3D printing. They differ in that they create assemblies in the form of available materials and in different layers of construction. Common materials for 3D printing include nylon glass fiber, durable nylon material, gypsum material, aluminum material, titanium alloy, stainless steel, silver plating, gold plating and rubber materials.
