What is 3D Printing? Generally speaking, it is a kind of rapid prototyping technology, also known as additive manufacturing. And it is a technology based on digital model file, using powder metal or plastic and other adhesive materials to construct objects by layer printing.
3D printing is usually realized by digital technology material printer. Moreover, it is often used in mold manufacturing, industrial design and other fields to make models. Now it is gradually used in the direct manufacturing of some products. In fact, there are already parts printed by this technology.
Applications of 3D printing
Nowadays, 3D printing technology is applied in many aspects. For exampple, it has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information system, civil engineering, guns and other fields.
Let’s look at two concrete examples.
Firstly, On January 14, 2019, the University of California, San Diego, for the first time, used fast 3D printing technology to manufacture a spinal cord scaffold that mimics the structure of the central nervous system, successfully helping rats recover their motor function.
Secondly, On May 5, 2020, China’s first successful long march 5B carrier rocket was equipped with a “3D printer”. This is the first space 3D printed experiment in China. And the first international 3D printed experiment of continuous fiber reinforced composites in space.
