With the increasing demand for innovative design and manufacturing of parts in the manufacturing field, emerging more complex design inspirations, which caused traditional processes cannot to meet the manufacturing needs of the complex features. The integral forming of complex parts can be achieved by additive manufacturing (AM) technology as a new manufacturing process, which with a high degree of freedom of manufacturing, and the material utilization rate is greatly improved compared with the traditional subtractive process. This paper introduces the airworthiness verification criteria for laser additive manufacturing technology and examines the quality control and airworthiness verification concepts within the AM process. It analyzes the airworthiness development process for materials and structural properties in additive manufacturing, presents the current key methods in additive manufacturing product design and airworthiness verification, and outlines the development direction and path for metal additive manufacturing airworthiness technology. The aim is to facilitate broader application of metal additive manufacturing in civil aircraft manufacturing.
