Abstract: The development of metal laser additive manufacturing technology provides a new way for lightweight design and integrated forming of complex aluminum alloy components in aerospace.However, high strength aluminum alloy laser additive manufacturing is faced with challenges such as low absorption rate, easy oxidation and burning, and high sensitivity to crack.To address these challenges, domestic and foreign scholars carried out a series of studies from the aspects of composition design and process optimization, which laid a foundation for the shape regulation and engineering application of high strength aluminum alloy laser additive manufacturing.The researches on composition design and process optimization of laser additive manufacturing of high strength aluminum alloy in recent years were reviewed, and the existing problems and future development trend of laser additive manufacturing of high strength aluminum alloy were summarized.
