3d printing technology is also called additive manufacturing technology, which is abbreviated as (rapid prototyping technology or layered manufacturing technology)

Extension of the basic definition of 3d printing technology;

3D printing (3DP) is a rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model file, using adhesive materials such as powder metal or plastic, and constructing objects by printing layer by layer.

3D printing is usually realized by a material printer using digital technology. It is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products. Parts already printed with this technology. This technology has been applied to jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobile, aerospace, dentistry and medical industry, education, geographic information system, civil engineering, guns and other fields.

3D printing technology appeared in the mid-1990s, and it is actually the latest rapid prototyping equipment using light curing and paper lamination technology. Its working principle is basically the same as that of ordinary printers. The printer is full of printing materials, such as liquid or powder. After connecting with the computer, the printed materials are superimposed layer by layer under the control of the computer, and finally the blueprint on the computer becomes a physical object. This printing technology is called 3D stereoscopic printing technology.
