Ordinary printers used in daily life can print flat objects designed by computers, and the so-called 3D printers work 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” that 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 3D rapid prototype printing technology.

Many different technologies exist for 3D printing. They differ in the way the materials are available and build the parts in different layers.

Common materials for 3D printing include nylon glass fiber, durable nylon material, gypsum material, aluminum material, titanium alloy, stainless steel, silver-plated, gold-plated, and rubber-like materials.
