Description

technical field [0001] The invention relates to a 3D printing manufacturing method of an aluminum-based olefin alloy thin-walled blade, and belongs to the technical field of 3D printing. Background technique [0002] Aluminum alloy has low density, high strength and good ductility, and is widely used in aviation, aerospace and other fields. As a structural material, how to improve the strength of aluminum alloy has always been the main direction of its researchers. At present, it is difficult to make breakthroughs in further improving the performance of aluminum alloys by changing the alloy smelting method, adjusting the composition, adjusting the heat treatment and deformation process, and aluminum matrix composites have emerged as the times require. Adding graphite, silicon carbide, boron carbide and carbon nanotubes to aluminum alloys to prepare aluminum matrix composites to improve the strength of the alloy has become a research direction for scholars. But the enhancem...
