3D printing material industry panorama
3D printing materials are an indispensable part of the 3D printing industry, and the level of 3D printing materials directly affects the development of the 3D printing industry. In recent years, the national level has become more and more serious in the face of China's 3D printing materials industry, and has basically formed a relatively mature industrial chain.
The upstream of 3D printing materials is the supply of basic materials and primary processing, such as non-ferrous metals industry, rubber processing industry, plastic processing industry, ceramic processing industry, etc., to provide standard materials for 3D printing materials. The midstream industry is the most important part of the 3D printing materials industry chain. The raw materials are processed by various technical means to make it a 3D printing material that conforms to the 3D printing standard. The current mainstream 3D printing materials are metal powder materials and photosensitive resins. Materials, photocurable resin materials, biomaterials, engineering plastic materials, and non-metal materials. The downstream industry is manufacturing 3D printing. With the advancement of technology, 3D printing manufacturing applications are more and more widely used in engineering machinery, aerospace, biomedicine, automobile manufacturing and other fields.
The upstream industry of 3D printing materials has a history of many years of development, forming a relatively mature raw material supply system. The number of upstream industry companies is large, the industry scale is huge, and the market tends to be completely competitive, which can provide a good foundation for the development of 3D printing materials industry. Representative companies are China Aluminum, Shandong Gold, Tongling Nonferrous Metal, Baoti Titanium, etc. in the non-ferrous metals industry; Hainan Rubber, Sinochem International, Double Arrow Rubber, and Huanghai Rubber in the rubber industry.
Metal powder 3D printing materials and light curing resin 3D printing materials are 3D printing materials commonly used in China's 3D printing industry.

The development of representative companies are metal powder materials such as AVIC Matt, Suzhou Innate, Rongtian Airlines, Sailong Metal, etc.; Luantai, Zhuhai Xitong, Plastic Technology, Dongguan Zhiwei Wait.
In recent years, China's 3D printing industry has developed rapidly. 3D printing materials, as the upstream industry of the 3D printing industry, have also risen. Unlike ordinary materials, 3D printing materials need to be prepared using unique technologies to meet 3D printing products. Special requirements for materials in 3D printing equipment. The main 3D printing materials on the market include ABS plastic materials, PLA materials, rubber materials, metal powder materials, ceramic materials, and new composite gypsum powders, epoxy resins, and wax materials.
Multi-factors help the industry develop and the market scale continues to grow.
China's 3D printing materials industry began to emerge with the gradual development of 3D printing in the world and its use in China. Although it started late, it is stimulating the development of China's 3D printing materials industry due to the huge demand in the downstream market. With the help of many factors, the development prospect of China's 3D printing materials industry is very broad.
In the political environment, the state supports key industries such as 3D printed materials. The introduction of "Made in China 2025", "Special Plan for Scientific and Technological Innovation in the "13th Five-Year Plan" Material Field" and "Incremental Manufacturing Industry Development Action Plan (2017-2020)" provide guarantee for the development of 3D printing materials in China. . In the economic environment, traditional manufacturing is in urgent need of transformation, and developing 3D printing is an effective way of intelligent manufacturing. The traditional manufacturing industry has developed slowly in recent years, and the continuous improvement of human capital and technology has made many traditional manufacturing industries miserable. And 3D printing is an effective way to transform traditional manufacturing. With the increasing demand for 3D printing in these industries, the development of 3D printing industry will be faster and faster, as the upstream industry of 3D printing, 3D printing. The vast market for materials has caused the entry of a large number of companies at home and abroad.
In the social environment, the cost of manpower and raw materials has increased, and manufacturing is in urgent need of new production methods to improve efficiency and efficiency. Due to the high price of foreign materials and the poor quality of domestic materials, 3D printing has fewer applications. As China's manpower and raw material costs increase, some manufacturing industries have to seek transformation. This provides a certain market foundation for the development of 3D printed materials in China. In the technical environment, foreign 3D printing related patents have expired, and the research team can transform the feasibility study into industrial value. The technical threshold of 3D printing materials is relatively high. Until recently, due to the expiration of foreign 3D printing related patents, the Chinese 3D printing industry has begun to develop. The spread of foreign technology has accelerated the development of the domestic 3D printing materials industry. .
The superstructure has a good guiding role and promotion role for the development of economic foundation. The rapid development of 3D printed materials in China cannot be separated from the support and guidance of national policies. In 2015, "Made in China 2025" listed bio-3D printing technology as one of the key support areas, and subsequently issued the "Additive Manufacturing Industry Development Action Plan (2017-2020)", "Major technical equipment and product import key components, The Catalogue of Raw Materials Commodities, the Major Technical Equipment and Product Catalogue Supported by the State, and the Three-Year Action Plan for Enhancing the Core Competence of Manufacturing (2018-2020), etc., which promote the 3D printed materials industry, these policies Support the development of the 3D printing materials industry from the development of industry development goals, financial subsidies, and inclusion in key areas.
China's 3D printing industry has developed rapidly. In the past five years, it has maintained a growth rate of more than 25%. In 2017, the market size of China's 3D printing industry was about 1.67 billion US dollars, and it is expected to reach 2.09 billion US dollars in 2018. The rapid development of the 3D printing industry has brought about the continuous expansion of 3D printing applications, and different application fields have put forward new demands for 3D printing technology and 3D printing materials.
Due to the double stimulation of demand + policy, the scale of China's 3D printed materials market has maintained rapid growth. In 2012-2017, the scale of China's 3D printed materials market has maintained a growth rate of more than 35%, from 260 million yuan in 2012 to 2017. 2.92 billion yuan, it is estimated that in 2018, China's 3D printed materials market will reach 4 billion yuan, and the growth rate will remain above 35%.
From the proportion of 3D printing materials market to the scale of 3D printing market, the proportion of 3D printing materials has gradually increased, from 25% in 2012 to 27.6% in 2017. It is expected to increase further in 2018, reaching 28.60%. . The increasing proportion of the market indicates that the growth rate of China's 3D printing materials market is slightly faster than the growth rate of China's 3D printing market. It also reflects the growing importance of the 3D printing materials industry in the entire 3D printing industry.
Mechanical and aerospace applications are the most used, metals and plastics dominate the mainstream
In the field of application, due to the high requirements for component quality and customization in the fields of industrial machinery, automobile manufacturing, and aerospace, the downstream application fields of 3D printing materials in China are mainly concentrated in the fields of industrial machinery, automobile manufacturing, and aerospace. In the first half of 2018, 3D printing materials were mainly used in industrial machinery, aerospace and automotive fields, accounting for more than 50% of the total, of which industrial applications accounted for 20%, aerospace applications accounted for 18.90%, automotive applications accounted for More than 16.00%.
Since the downstream application of 3D printing materials is mainly equipment manufacturing, the 3D printing materials used are mainly metal materials, including titanium alloys, aluminum alloys, stainless steels and other metal materials, and the total proportion of metal materials exceeds 40%; Engineering plastics such as ABS, nylon, and PLA account for more than 10% of mainstream 3D printing materials.
The scale of the industry is still low, and localization is the future development trend.
There are considerable gaps in the basic research, material preparation process and industrialization of domestic 3D printing materials compared with foreign countries. There are few domestic companies capable of producing 3D printing materials, mainly relying on imports, which has resulted in 3D printing products. The high cost has affected the industrialization process. In general, China's domestic 3D printing materials industry has problems such as low scale of Zhejiang industry, lagging development of special materials, high-end materials need to be imported, and industry standard systems are not perfect.
In 2018, more than 100 new 3D printed materials were introduced worldwide. The increase in the variety of 3D printing materials has made 3D printing technology applicable to many fields, and the variety of products that can be manufactured by using 3D printing technology has greatly promoted the development of the 3D printing industry. The increase in the variety of 3D printing materials has promoted the expansion of the 3D printing market. At the same time, the development of 3D printing materials technology has gradually reduced the cost of 3D printing materials, enabling more 3D printing technologies to be transformed into industrial applications. Further expansion.
In 2018, there are also new 3D printing materials in China. The team of the College of Chemistry and Chemical Engineering of Nanjing University has developed a new polymer material that is “rigid and flexible”, which solves the problem of balance between mechanical strength and self-repairing properties. It can be changed according to temperature changes, and new materials are expected to be well applied in fields such as medical external fixation brackets and 3D printing.
At present, the production of 3D printed materials in China is relatively backward. Most 3D printed materials are also dependent on foreign imports. The “Special Plan for Scientific and Technological Innovation in the “13th Five-Year” Material Sector” proposes that by 2020, more than 80% of materials will be localized, and the 3D printed materials market will It will face huge development space, and the demand side will put forward new requirements to promote the continuous development of the market scale of the 3D printing materials industry.
With the continuous introduction of the corresponding support policies of the country and the continuous improvement of China's domestic materials technology, the market scale of China's 3D printing materials industry will continue to maintain a rapid growth momentum, and the cost will gradually decline, making 3D printing technology out of the island and more applications. In the downstream field. In the future, China's 3D printing materials industry will show a higher level of localization; the proportion of high-performance metal powder materials will increase; and the development of medicine, aviation, and automobiles will be faster.
