How to promote the industrialization of 3D printing in China

current situation and existing problems of 3D printing industrialization in China

(I) development status

1. A number of basic research achievements and technologies have been achieved; 2. The laser direct forming technology of high-performance metal parts is world leading; 3. Preliminary progress has been made in industrialization

(II) problems

although 3D printing technology in China has made great progress, it is still in the initial stage of industrialization on the whole, mainly manifested in:

1. Lack of public technology platform. China has not yet established a public technology platform for 3D printing, lacks the integration of industry, University and research institutions, colleges and universities, scientific research institutions are fighting on their own, the motivation for cooperative research is insufficient, an open and integrated innovation system has not yet been formed, and there is a lack of technical compatibility and standard formulation

2. The industrialization of 3D printing in China is still in its infancy. In 2012, the market size of China's 3D printing industry was about 1.2 billion yuan, less than 9% of the world. The sales of 3D printing equipment accounts for only 8.7% of the world, and the sales revenue of 3D printing equipment and sales revenue is about 500million yuan, accounting for less than 4% of the world. More than half of the 3D printing equipment depends on imports

3. the industrial chain has not been effectively formed.

China has not yet established a 3D printing enterprise specializing in material preparation and software development, and lacks a complete industrial chain covering software development, material preparation, equipment production and services. Intermediary institutions engaged in testing and verification, finance, e-commerce, intellectual property protection, etc. are also imperfect. In addition, at present, domestic 3D printing enterprises are still in the preliminary development stage of fighting alone, the degree of industrial integration is low, the leading technical standards and development platforms have not been established, and the technology research and development, promotion and application are still in a disordered state

4. Lack of education, training and social promotion

at present, the number of 3D printing equipment purchased by enterprises is very limited, and most of them are imported from abroad, and the scope of application is relatively narrow. In the teaching curriculum system of mechanical, materials, information technology and other engineering subjects, there is a lack of compulsory links related to 3D printing, and 3D printing is still at the level of extracurricular Interest Research of some students

the situation faced by the development of China's 3D printing industry

(I) development opportunities

1. the acceleration of industrial transformation and upgrading is conducive to the rapid expansion of 3D printing market demand

in recent years, with the rapid rise in the cost of land, labor and other factors, China's industrial transformation and upgrading is becoming more and more urgent. Under this background, the pace of China's industrial transformation and upgrading will be further accelerated, and Chinese enterprises are eager to shorten the life cycle of new products, The demand for improving product design capabilities continues to increase, which will continue to increase the demand for the development of 3D printing devices with product design and prototype development

2. With the rapid development of aerospace and national defense military industry, the demand for 3D printing equipment is increasing.

China is in the period of rapid development of aerospace and national defense military industry. Aviation equipment, satellites and applications have been included in the national strategic emerging industries for key support. 3D printing technologies such as laser near net shape forming will have greater development space in the manufacturing of complex and difficult aircraft and satellite parts

3. China attaches great importance to technological innovation and industrialized application, which will promote the rapid development of 3D printing industry.

China takes innovation driven development as a national strategy to transform the development mode and accelerate industrial transformation and upgrading, and continuously increases the R & D investment in technological innovation and industrialized application. As an emerging industry, 3D printing is expected to be included in the strategic emerging industry supported by the state, and technological innovation and industrialization will usher in a favorable policy environment

(II) facing challenges

1. the world's major economies are extremely large and seize the commanding height of industrial development

in order to seize the strategic commanding height of this emerging technology and industrial development, the world's major economies have made strategic deployment, formulated development plans and support policies. In August, 2012, the U.S. government announced the establishment of the national 3D printing Innovation Institute. In the first phase, the federal government and enterprises invested $70million in research and development to support the research, development and application of 3D printing technology, and strive to make the United States an excellent 3D printing center in the world; Since 2011, the British government has continued to increase research and development funding for 3D printing technology, and set up a number of 3D printing research centers, etc

2.the international market competition of 3D printing enterprises is becoming increasingly fierce

in recent years, with the continuous maturity of technology and the approaching expiration of patent rights, 3D printing enterprises in developed countries in Europe and the United States have shown two major trends: one is to expand enterprises through mergers and acquisitions or mergers, and the other is to reduce the price of 3D printing equipment. This will have an impact on our domestic 3D printing industry, which is not highly industrialized

3. In terms of 3D printing consumer goods industry, China relies on foreign market consumption grade

3D printers. China is still in the market cultivation period, and the market demand is obviously insufficient. Even for industrial 3D printers, Chinese user enterprises are not aware of using 3D printers for product development and prototype manufacturing

China's path of 3D printing industrialization

(I) guiding ideology

adhere to the new road of industrialization and promote informatization. These innovative technologies can meet the needs of the Asian market for increasingly demanding packaging materials, deeply integrate with industrialization, face the needs of the transformation and upgrading of key industries in the national economy and the cultivation and development of strategic emerging industries, and achieve the goal of digitizing the manufacturing process and transforming the manufacturing mode, With the breakthrough of key core technologies as the support, the promotion of the R & D and industrialization of 3D printing equipment as the core, and the improvement of the integration and innovation ability of 3D printing equipment as the focus, promote the demonstration and application promotion, adjust and optimize the industrial organization structure, and enhance the international competitiveness of the industry
