Abstract: A solid composite additive manufacturing method for high-performance structural component includes: the rod-shaped raw material of solid composite additive is heated to a solid solution temperature, wherein the rod-shaped raw material is prepared by casting method; the rod-shaped raw material of the solid composite additive after solid solution is loaded into the extrusion die and extruded into a set shape; The raw materials of the extruded solid composite additive are laid on the base plate layer by layer according to the track by rolling or other pressure connection methods to form the prefabricated billet of the solid composite additive. The prefabricated billet is processed by numerical control to obtain metal part. The solid composite additive manufacturing method refines the grain, breaks the oxide film, and improves the mechanical properties of the structural component.
