3D printing, that is, a kind of rapid prototyping technology, it is a kind of digital model file as the basis, the use of powdered metal or plastic and other bondable materials, through the way of layer by layer printing to construct the object of the technology. 3D printing is usually the use of digital technology material printer to realize. Often in the mold manufacturing, industrial design and other fields are used to manufacture models, and then gradually used in the direct manufacture of some products, there has been the use of this technology printed parts.
With the development and popularization of 3D printing, as a complementary product of 3D printing, three-dimensional digitizing technology will also get a huge boost. Currently, 3D printing technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems (GIS), civil engineering, as well as other fields. The overall global 3D equipment and pictures and models market is forecast to reach $7,735 million in 2018, growing at a CAGR of 47.99%.
