The C919 is a large civil airliner independently developed by China and a major achievement in China's aviation industry. The C919 not only competes with the international level in design and performance, but even surpasses similar foreign models in some aspects. The most surprising thing is that C919 does not have a single screw, but uses China's self-developed 3D laser printing technology to melt and coagulate each part of the aircraft with metal powder, thereby achieving the overall weight and strength of the aircraft. This technology not only saves a lot of materials and costs, but also improves the safety and reliability of the aircraft. This technology is the first of its kind in the world, shocking and panicking Western countries such as the United States.
3D laser printing technology is a technology that uses a laser beam to stack metal powder or other materials layer by layer, also known as additive manufacturing technology. This technology can print objects of any shape and structure based on computer-designed three-dimensional models, without the use of any molds or tools. This technology can greatly reduce waste and errors in the processing process, and improve production efficiency and quality. This technology has a wide range of applications in aviation, aerospace, automotive, medical and other fields.
China is already at the forefront of 3D laser printing technology and has successfully applied this technology to the C919 aircraft. According to reports, more than 500 parts on the C919 aircraft were manufactured using 3D laser printing technology, including flight control systems, engine mounts, landing gear, windshield window frames and other important components. Not only are these components lighter, stronger and longer-lasting, they also eliminate the need for traditional welding and riveting processes, reducing the risk of structural defects and stress concentrations. The overall weight of the C919 aircraft is said to be about 10% lighter than comparable models, and fuel consumption is also reduced by about 15%.
The 3D laser printing technology of the C919 aircraft not only demonstrates China's innovation ability and leading position in the aviation industry, but also poses a huge impact and threat to Western countries such as the United States. The United States has been the world's largest civil aircraft manufacturer, and its Boeing and Airbus products account for the vast majority of the global market. However, the United States lags far behind China in 3D laser printing technology, and the number and quality of 3D printed parts used on its aircraft are not as good as China's C919. Some experts and media in the United States have also acknowledged China's advantages in this regard, and warned that if the United States does not accelerate the development and application of 3D laser printing technology, it will lose the competitiveness and dominance of the aviation industry#Current Affairs Hot Headlines said#
