China Manufacturing 2025 brings opportunities and development space for the 3D printing industry

1. Policy support
    With the explosive global development of 3D printing in recent years, 3D printing has long been a popular "nationality" for local and local governments. Although "Made in China 2025" was proposed in 2015, China's dream of building an industrial manufacturing powerhouse has long been there. In recent years, the state and local governments have been promulgating favorable policies for 3D printing to promote the healthy and healthy development of the 3D printing industry.
    In 2013, the Ministry of Science and Technology announced the “National High-Tech Research and Development Program and the National Science and Technology Support Program Manufacturing Sector 2014 Annual Project Collection Guide” for the first time to include the 3D printing industry.
    In March 2014, the Beijing Municipal Science and Technology Commission announced the “Working Opinions on Promoting Beijing's Additive Manufacturing (3D Printing) Technology Innovation and Industrial Cultivation”: set up a major project of 3D printing technology to support all-round industrial chain technology innovation in 3D printing. Continue to promote the development of the 3D printing industry.

    In February 2015, the Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Finance issued the “National Additive Manufacturing Industry Development Promotion Plan (2015-2016) Year”, and the 3D printing industry ushered in the first “national level” development plan.

    During the "two sessions" in March 2015, Premier Li Keqiang’s government report proposed three specific measures, "Made in China 2025", "Internet +" Action Plan, "Volkswagen Entrepreneurship, and Innovative Innovation", which formed a new normal to promote China's economic development. New ideas, these three specific measures are closely related to 3D printing.
    In May 2015, Shanghai established the first officially registered additive manufacturing industry association in China. At present, there are nearly 100 member companies. The association has gathered the strengths of upstream and downstream of the industrial chain to jointly promote independent innovation and industry standards for 3D printing technology. Develop and explore new formats and new models for 3D printing.
    In May 2015, the introduction of "Made in China 2025" not only further clarified the direction of industrial development, but also demonstrated the government's determination to develop the 3D printing industry.
    In March 2016, China issued the “2016 Annual Application Guide for Additive Manufacturing Majors”, which focused on breaking through the basic theories of additive manufacturing and laser manufacturing, core components, and key process technology setting tasks. In 2016, the first batch was added. Manufacturing and laser manufacturing started 29 projects in both directions.
    In April 2016, the National Additive Manufacturing Standardization Technical Committee was established. The establishment of the National Additive Manufacturing Standardization Technical Committee is of great significance for promoting the standardization of additive manufacturing and promoting the development of additive manufacturing technologies and industries.

    2.3D printing application prospects in the aerospace field
    As mentioned in the "Made in China 2025" aerospace equipment strategy, China has huge market space for air transportation and general aviation services. It is estimated that in the next 10 years, the world will need 12,000 trunk aircraft, 22,700 regional aircraft, 18,300 general-purpose aircraft and 12,000 helicopters, with a total value of about 2 trillion US dollars. At present, 3D printing additive manufacturing has carried out many tests and application verification in the aviation field. Foreign media reports that some 3D printed metal parts have been applied in the Airbus A350.
    At the same time, in the "Made in China 2025", we have made many strategic plans for the innovation and development of China's aerospace technology. Among the key technologies that 3D printing additive manufacturing technology can be involved in are:
    (1) Large-scale lightweight overall and high-strength metal structure manufacturing technology
The main components of the fuselage siding, wing siding, landing gear, frame beam ribs, etc., focus on the manufacturing process of titanium alloy, aluminum alloy, aluminum-lithium alloy, high-strength steel and other metal structures.

    (2) Aeroengine key components
    Titanium/resin-based composite fan and composite fan machine with advanced large bypass and fan system wide-chopped and swept design;
    Single crystal/ceramic matrix composite high pressure turbine blade;
    High-load, high-efficiency, long-life turbine technology, including single crystal/ceramic-based composite turbine blade technology;
    Aeroengine key parts remanufacturing technology, including the re-manufacturing of key parts such as turbine blades and turbine disks;
    Advanced materials and manufacturing of aero-engines, forming advanced materials and manufacturing R&D systems, building R&D and verification systems for green manufacturing, precision manufacturing and intelligent manufacturing of titanium alloys, superalloys and advanced composite materials, and promoting the application in the aero-engine industry. Meet the development cycle and economic affordability needs;

    (3) Aerospace equipment manufacturing
    Key technologies for manned space and on-orbit maintenance and service;
    Construction of a near-surface space station assembly;
    Spacecraft components in orbit 3D printing manufacturing;
    Key technologies such as man-machine collaborative space facility construction and on-orbit maintenance services;

    3. Marine engineering equipment and high-tech ships
    Since the awakening of China's ocean consciousness in 2012, the development of marine engineering equipment and high-tech ships has received more and more attention from the state. Marine engineering equipment and high-tech vessels are the main carriers and means for human development, utilization and protection of marine mineral resources, marine renewable energy, marine chemical resources, marine biological resources and marine space resources, as well as marine transportation activities. The shipbuilding industry is an important part of China's strategic emerging industries and a pioneering industry for the development of the marine economy.
    In "Made in China 2025", many strategic plans have been made for the development of China's shipbuilding industry. The key technologies that can be involved in 3D printing additive manufacturing are:
    (1) Ship propulsion device design technology
    Focus on high-efficiency propeller optimization design technology, POD-CRP combined propulsion device design technology, propeller/rudder integrated design technology, propeller/ship optimization matching design technology, high-efficiency rim-to-rotation combined       propulsion technology, stacked-leaf twin-propeller rotary propulsion Such technology is reasonably integrated.
    (2) Ship intelligent design and manufacturing technology
Ship design and construction integrated design 3D technology, efficient propulsion and navigation safety design technology; ship intelligent welding technology, ship intelligent manufacturing integrated platform technology, ship intelligent manufacturing equipment technology.
