The history of 3D printing

Time:2020-4-20 Author:

3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing [1], it is a kind of digital model file as the basis, the use of powdered metal or plastic and other bondable materials, printed layer by layer Ways to construct the technology of objects.

3D printing is usually achieved by using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns, and other fields. [2] 

On January 14, 2019, the University of California, San Diego used fast 3D printing technology for the first time to create a spinal cord stent that mimics the structure of the central nervous system, which successfully helped rats restore motor function.

On May 5, 2020, China's first successful Long March 5B carrier rocket was equipped with a "3D printer." This is China's first space 3D printing experiment and the first international 3D printing experiment of continuous fiber reinforced composite materials in space.
