[ Chemical Machinery Equipment Network Industry News ] Benefiting from the advancement of 3D printing technology and the outbreak of market demand, the 3D printing industry has entered a period of rapid growth, which in turn has also stimulated the development of related industrial chains such as 3D printer accessories, 3D printing materials and 3D printing services.
development
.
In particular, the scale of the 3D printing material industry has continued to expand and the variety has become increasingly rich, which is becoming an important driving force for 3D printing technology

With the in-depth development and integration of 3D printing technology, it can not only be used in mold manufacturing, industrial design and other fields to manufacture models, but also gradually used in the direct manufacturing of some products, and the market scale is rapidly expanding
.
The data shows that the world 3D printing market size in 2020 is about 15.
4 billion US dollars, and the Chinese 3D printing scale is about 4.
4 billion US dollars.
It is expected that the world 3D printing market size is expected to reach 34.
9 billion US dollars in 2023
.

According to incomplete statistics, the industrial applications of 3D printing technology are mainly distributed in consumer electronics, automobiles, molds, medical care, aerospace, construction, shipbuilding, nuclear industry, scientific research and other fields; according to the specific application links, 3D printing technology is currently mainly used.
It is used in the production of design samples, display models and molds, and has become an important realization of product design, repair and rapid prototyping
.

　　From the perspective of supply, the current large-scale 3D printing revenue is mainly focused on the industrial field
.
According to preliminary statistics, there are 29 Chinese companies with 3D printing-related business revenue exceeding 100 million yuan in 2020, of which 16 are industrial-grade, accounting for 57%; 12 are consumer-grade, accounting for 43%
.
With the deepening of the scale of 3D printing, the equipment and materials are becoming more and more mature and stable, especially the categories of 3D printing materials are becoming more and more abundant
.

　　So, what are the materials used for 3D printing?

　　3D printing materials mainly include photosensitive resin materials, engineering plastic materials, metal materials, ceramic materials, biological materials, rubber materials, graphene materials, etc.
Specifically:

　　Photosensitive resin material: Under the irradiation of ultraviolet rays, when this type of material is bonded, the polymer is transformed from a colloidal resin into a hard substance, which has the characteristics of high mechanical degree, no volatile odor, wide application field, and easy storage
.

　　The 3D printer jets layers of finely curable liquid photosensitive resin onto a build tray and cures it using UV light, accumulating these thin layers to create precise prototypes or production parts
.

　　Engineering plastic materials: including ABS materials, polycarbonate materials and polyamide materials
.
ABS material is very easy to print, and the extruders on the market can extrude it very smoothly
.
3D printers can print these materials by spraying a single material at a time, or spraying a variety of basic materials at the same time to print products that are used in the manufacturing industry, chemical industry and other fields
.
ABS will produce a strong odor when printing, it is recyclable and non-degradable, but it has high strength, good toughness, and high dimensional stability.
It is a very commonly used 3D printing material on the market

　　Metal materials: titanium alloy materials, aluminum alloy materials, stainless steel materials,
etc.
These materials cooperate with 3D printing technology, and the products produced are widely used in the field of medical devices and other fields that have special requirements for materials
.

　　Ceramic materials: including clay, kaolin and other natural silicate materials and oxide ceramic materials, nitride ceramic materials, carbide ceramic materials,
etc.
These materials have the advantages of high hardness, high temperature resistance, and stable physical and chemical properties that polymers and metal materials do not have.
Therefore, 3D printed products have broad application prospects in aerospace, automotive, biomedical and other industries
.

　　Biomaterials: There are biomedical metal materials, biomedical polymer materials, biomedical ceramic materials and biologically derived materials, such as polylactic acid (PLA), collagen, silk protein,
etc.
Polylactic acid (PLA) is a derivative of renewable resources (starch, corn), with no irritating odor and low cost.
It is used in 3D printers.
The printed products are used in consumer, medical and other fields, with bright colors and gloss.
Good, will not shrink and so on
.

　　Rubber material: has the advantages of Shore A hardness, elongation at break, tear strength and tensile strength
.
Therefore, rubber materials are combined with 3D printers, and 3D printed rubber products are mostly used in consumer electronics, medical equipment, and automotive interior materials
.

　　Graphene material: It has many advantages such as excellent optical, electrical, and mechanical properties.
It can be used in 3D printing products to replace various traditional materials.
Broad application potential
.

　　Acrylic material: Also known as plexiglass, it is an earlier developed plastic polymer material
.
The material has good transparency, beautiful appearance, easy processing, easy dyeing, and good abrasion resistance, high temperature resistance and chemical stability
.
Therefore, the products printed by 3D printers are mainly used in the construction, industrial and advertising, and lighting industries
