Pure copper and copper alloys are widely recognized and applied in industries due to their good thermal conductivity, electrical conductivity, ductility and other characteristics. Based on the 532 nm nanosecond pulse laser, this thesis initially explore the influence of several pulse laser processing parameters (such as average power, scanning speed, spot size, etc.) on the forming of pure copper and copper alloys, and through optimized processing parameters, this thesis manufactures some pure copper and copper alloy samples by versus of 3D printing to verify the feasibility of 532 nm nanosecond pulse laser.
