Laser additive manufacturing (AM) technology has great advantages for producing metal components with complex structures. The high reflectivity metals exhibit different laser absorptivity under different wavelengths. To obtain high-quality AM parts, short wavelength laser sources such as blue laser and green laser can be used to manufacture high reflectivity metal materials. In the present manuscript, the absorption mechanism of laser source has been introduced. The current status of blue laser has been summarized. The research status of selective laser melting and laser deposition technologies using blue laser source of high reflectivity metals have been analyzed and summarized. In addition, its future development trend has also been prospected.<正文<参考文献原文> HORN T J, HARRYSSON O L A. Overview of current additive manufacturing technologies and selected applications［J］.
