China Eastern Successfully Uses 3D Printing Technology to Make Aircraft Parts

China Eastern Airlines Technology Co., Ltd. has successfully implemented 3D printing technology to install aircraft cabin door handle covers and seat signs on a newly delivered Boeing 777-300ER passenger aircraft, allowing it to enter regular service. This marks China Eastern Airlines as the first airline in the country to adopt 3D printing for manufacturing aviation parts, setting a new benchmark in the industry. According to reports, the company has integrated 3D printing with advanced technologies such as mathematical modeling, materials science, aircraft structure design, and rapid prototyping. The process begins with computer-aided design, where digital models of aircraft components are sliced into layers. These designs are then sent to 3D printers, which build the parts layer by layer using additive manufacturing techniques. This method allows for the production of highly accurate components in one single process, significantly improving efficiency and reducing lead times. Leveraging the flexibility, ease of assembly, and quick replacement capabilities of 3D printing, China Eastern Airlines has enhanced its supply chain operations, lowered procurement costs, and established a full-cycle process for component design and manufacturing. This has enabled them to customize cabin interiors and expand their capabilities into business jet modifications and other aerospace applications, showcasing strong engineering expertise and broadening their presence in the aerospace manufacturing sector. Furthermore, China Eastern Airlines Technology Co., Ltd. has been authorized by the Civil Aviation Administration of China to serve as an approved unit for aircraft modification design. The successful application of 3D printing technology has allowed the company to develop a complete production process—from retrofit design and component development to manufacturing and installation—helping it build a competitive edge in specialized production and industrialization. This positions the company as a leader in providing comprehensive lifecycle maintenance services within the aviation industry. (Reporter)
