Zusammenfassung:A method for forming precise porous metal structure by selective laser melting, including 3D design, data processing, parameter setting and selective sintering, including the following steps: A. designing 3D model of precise and porous structure; B. adding support structure and slicing; C. setting parameters of laser scanning and beam offset; and D. arranging a soft recoater in the forming system. After coating the metal powder on the forming plate, the fiber laser emits a laser to melt the metal powder to form a single-layer cross section of the porous structure; E. lowering the forming plate by one layer, and repeating steps D-E, so that the metal powder is melted and accumulated layer by layer until the formed components of porous structure are obtained.
