ZHU Zhongliang, ZHAO Kai, GUO Lijie, et al. Application and development trend of additive manufacturing technology of large-scale metal component in aerospace manufacturing[J]. 2020,50(1):1-14. DOI： 10.7512/j.issn.1001-2303.2020.01.01.
Additive manufacturing is an advanced manufacturing technology with great potential,which is suitable for aerospace manufacturing which requires light weight and high strength. The principles and characteristics of different kinds of additive manufacturing are briefly expounded,and the research status of additive manufacturing in key technical directions such as forming equipment,forming organization and performance regulation, topology design and optimization,forming process simulation,heat source planning and control software,online detection and control,residual stress and crack porosity control,and auxiliary manufacturing measures are introduced. Application examples of additive manufacturing for large-scale metal components are presented. The existing problems and development trend of additive manufacturing technology of large-scale metal component in aerospace manufacturing are discussed.
