Abstract Additive manufacturing is one of the development directions of advanced manufacturing technology. The application of civil aircraft additive manufacturing technology depends on the maturity of additive manufacturing technology, airworthiness verification technology and the perfection of material standard system. In this paper, A–100 and TC18 materials used in the typical structure of landing gear of civil aircraft are studied in the application of laser / electron beam additive manufacturing technology, and a material and process certification, mechanical property characterization, internal quality control and nondestructive testing evaluation system meeting the airworthiness requirements is established.
