增材制造技术在航空航天领域的应用与发展OA

Parts manufacturing in the aerospace field demands exceptionally high product performance,accelerated research and development cycles,and lightweight.Compared to conventional manufacturing techniques,additive manufacturing(AM)offers significant advantages,including rapid prototyping,the ability to fabricate complex spatial structures,and integrated lightweight design and manufacturing.These attributes establish AM as a rapid and reliable technical pathway for aerospace component production.The applications of 6 kinds of AM technologies,such as laser powder bed fusion,electron beam melting,wire and arc additive manufacturing,direct energy deposition,fused deposition modeling,and multi-material additive manufacturing printing in the aerospace field are systematically reviewed.Furthermore,the manufacturing characteristics of each technology are also introduced.The design principles and applications of three design methods,namely,topology optimization,machine learning,and digital twin technology,based on additive manufacturing in aerospace are introduced.Finally,the current challenges are identified and future development prospects for AM in aerospace are outlined,providing a reference for the research in this domain.
