3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is built on a digital model file, using bondable materials such as powdered metal or plastic, and is printed layer by layer. Object technology.
3D printing is usually achieved using digital technology material printers. It is often used in the field of mold manufacturing, industrial design to make models, and gradually used in the direct manufacture of some products. There are already parts printed using this technique. The technology is widely used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, etc.
On January 14, 2019, the University of California San Diego used rapid 3D printing technology to create a spinal cord scaffold that mimics the structure of the central nervous system for the first time, successfully helping rats recover motor function.
On May 5, 2020, China's first Long March V B launch vehicle successfully equipped with a "3D printer. This is the first space 3D printing experiment in China and the first space 3D printing experiment of continuous fiber reinforced composite materials in the world.
Application of 3D printing in medical field. It is an excellent tool for personalizing care according to the needs of patients, while simplifying the operation of doctors, nurses, pharmacists and other professionals.
