Promote industry upgrading and technical innovation to support policies.
Major aerospace powers all around the world have lately adopted a set of policies to help metal 3D printing technology grow in the aerospace sector. Aiming to generate an external environment fit for technical innovation and industrial upgrading, these policies cover many facets including technology research and development, industrial application, standard establishing, and talent development.
The government of China gives additive manufacturing (i.e. 3D printing) technology great significance and has subsequently published a sequence of industrial policy plans including the "Action Plan for the Development of Additive Manufacturing Industry (2017-2020)" and the "14th Five Year Plan for the Development of Intelligent Manufacturing". These policies not only define the development goals, important tasks, and safeguard measures of the additive manufacturing industry, but also suggest particular measures such strengthening technological innovation, promoting industrial application, improving the standard system, and optimising the development environment, so offering strong policy support for the application of metal 3D printing technology in the aerospace industry.
America and Europe have also aggressively adopted policies to advance metal 3D printing technology development in the aerospace sector. For instance, the US government's "Make America" program and NASA's "Space Manufacturing" project, so encouraging the use of 3D printing technology in the aerospace sector, have raised investment in its research and development by the government. Through research initiatives like Horizon 2020, Europe encourages the creativity and use of 3D printing technology, therefore encouraging the change and upgrading of the aerospace sector.
The regulatory environment should guarantee equal focus on quality and safety.
Although metal 3D printing technology offers several benefits for the aerospace sector, safety and quality issues abound as well. Therefore, government regulatory authorities have also improved the safety and quality monitoring of metal 3D printing products even while they encourage technical innovation.
Product safety is rather important in the aircraft sector. Government regulatory authorities have developed a set of rigorous criteria and regulations to fully oversee the design, manufacture, testing, and other facets of metal 3D printing items thereby guaranteeing their safety. These criteria and specifications not only address the physical and chemical characteristics, fatigue life, and other facets of the product, but also clearly define quality control needs during the manufacturing process.
Government regulating bodies have also enhanced metal 3D printing technology's certification and evaluation. Establishing a specialised certification organisation to certify and assess metal 3D printing technology and products will help to guarantee their compliance with pertinent aerospace industry standards and criteria. Concurrently, the government supports businesses to enhance independent research and technological innovation, so fostering the ongoing development of metal 3D printing technology. Challenge and Reaction: Encouragement of Sustainable Industry
Metal 3D printing technology still presents several difficulties even if the aerospace sector has made great development in its application. These difficulties mostly consist in low material choice, excessive prices, and inadequate technological maturity. Governments and companies must cooperate to encourage continuous innovation and development in metal 3D printing technologies if we are to meet these problems.
Regarding technological maturity, the government should boost metal 3D printing technology research and development funding as well as assist industry uses of important innovations and achievements. Simultaneously, inspire businesses to increase industry university research cooperation and advance the thorough integration of technical innovation and industrial upgrading.
Regarding expenses, the government should help businesses to maximise manufacturing efficiency, lower prices, and streamline production lines. Furthermore, legislative assistance and finance subsidies help businesses to embrace metal 3D printing technology for manufacturing, therefore fostering its general usage in the aerospace sector.
Regarding the choice of materials, the government could support the deployment of metal 3D printing technology in more spheres and intensify research and development of fresh materials. Concurrent with this, inspire businesses to improve the general competitiveness of metal 3D printing technology by means of advanced technology and management expertise, foster collaboration and exchanges between domestic advanced businesses and foreign ones.
