In China's aviation manufacturing projects, achieving weight reduction design is an important goal, and 3D printing brings the feasibility of achieving weight reduction at the structural design level. Engine parts are assembled from multiple parts when manufactured using traditional processing methods, and the laser melting 3D printing process can directly realize the integration of multiple parts. This is one of the important ways for 3D printing technology to achieve lightweight aircraft.
The integrated design of the 3D-printed aircraft pipeline achieves the effect of lighter weight and lower cost. Metal 3D printing technology can produce special-shaped pipes, and its products can reduce assembly parts. In addition to reducing labor costs, it is also more conducive to maintenance. At present, the 3D-printed aircraft pipeline has passed the actual use test.
Because of its short processing cycle, designers can adjust the product structure in a relatively short time, and verify and compare them to ensure the optimization of the design. With 3D printing, there is no need for mold opening costs, and designers can easily make structural improvements for each product suitable for its use conditions according to actual processing needs.
Using industry-leading laser powder fusion 3D printing (SLM) technology, from product graphic optimization, 3D printing processing to post-processing, all production of the product was completed in a short period of time and delivered to use. After product index testing and functional testing, the product performance indicators fully meet or exceed the products manufactured by traditional craftsmanship. While quickly completing products that cannot be processed by traditional processes, the cost is reduced by about 30%.
At present, 3D printing technology has become a key technology to improve the design and manufacturing capabilities of spacecraft, and its application in the aerospace field continues to expand. At present, foreign companies and research institutions have used 3D printing to not only print out parts of aircraft, missiles, satellites, and manned spacecraft, but also to print out complete machines such as engines, drones, and micro-satellites. In terms of cost, cycle, weight, etc. Significant benefits have been achieved in this regard.
Metal powder melting 3D printing technology (SLM) has significant advantages such as high precision and high strength. It is the main application technology in the automotive research and development stage. We use 3D printers and raw materials to optimize product graphics, 3D printing, and processing, to post-processing, polishing, and polishing. Painting and assembly, etc., completed the production of this type of product within a very short period of time.
