摘要：
Material absorptivity in selective laser melting additive manufacturing is a problem with scientific and practical significance. Its study is a prerequisite for simulating process accuracy and defining a set of process conditions for the selected metal powder material to make it more suitable for selective laser melting and forming. This paper introduces the interaction mechanism between the laser and powder bed. It summarises widely used measurement methods of absorptivity in selective laser melting and reviews the progress of different methods in absorptivity research. The characteristics of various methods and their applications are comparatively analysed,focusing on the detailed discussion of the factors that may influence absorptivity. The paper concludes with a summary of the current research progress,significant problems,and an outlook on absorptivity research. © 2023 Cailiao Daobaoshe/ Materials Review. All rights reserved.
