3D printing materials are the material basis for the development of 3D printing technology
As 3D printing manufacturing technology changes the way and principle of the traditional manufacturing industry, it is a complement to the traditional manufacturing model. At the same time, 3D printing materials have become the main bottleneck restricting the development of 3D printing. It is also the key point and difficulty of 3D printing breakthrough innovation. Only by developing more new materials can the application field of 3D printing technology be expanded. At present, 3D printing materials mainly include polymer materials, metal materials, ceramic materials and composite materials.

As the saying goes: "It is difficult for a clever woman to be without rice." The same is true for a high-tech such as 3D printing. To a certain extent, printed materials are an indispensable material basis for printing technology, which determines the final product properties.
3D printing manufacturing technology consists of three key elements:
1. The product needs accurate three-dimensional design, using computer-aided design (CAD) tools to accurately position the product in all directions;
2. It is necessary to have strong molding equipment;
3. It is a material that needs to satisfy the product properties and molding process.
The 3D printing (additive) we mentioned above is relative to the material reduction. The material reduction refers to the use of separation technology to remove excess material from the substrate in an orderly manner, such as traditional car, milling and grinding. Drilling, planing, electric sparking and laser cutting are all reduced materials.
Traditional molding process laser cutting, resulting in material waste
Compression molding refers to the plasticity of the material mainly under the specific external force. The traditional forging, casting, powder metallurgy and other technologies are compression molding. Compression molding is mostly used for the molding of the blank stage, and there are also examples directly used for the molding of manual parts. For example, precision casting, precision forging, etc. are all formed by compression molding.
In the narrow sense, 3D printing technology mainly refers to additive manufacturing technology. From the perspective of molding process, 3D printing technology breaks through the limitations of traditional molding methods, and combines the rapid automatic molding system with computer data model without any additional process mold manufacturing. And machining can produce a variety of complex prototypes, so that the design and production cycle of the product is greatly shortened, and the production cost is greatly reduced.
The real advantage of 3D printing technology lies in its printing materials. 3D printing materials are an important material basis for the development of 3D printing technology. To some extent, the development of materials determines whether 3D printing can be used more widely. 3D printing can mimic the mechanical or thermal properties of plastic and metal materials, but this is also a major technical reason for restricting the development of 3D printing. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials. In addition, colored gypsum materials, artificial bone powder, cell biological materials and sugar materials are also available in 3D printing. The application.
