In aluminum 3d printing service, aluminum alloy materials have high specific strength and excellent corrosion resistance. 3d metal printing aluminum have been widely used in the automotive industry and aerospace and other fields. Studies have shown that the mechanical properties of aluminum alloy materials prepared by the SLM method exceed traditional casting materials and even reach plastic forming aluminum.
Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It is based on aluminum and is cast by adding Casting , iron, copper, manganese, magnesium, chromium, zinc, titanium and other metals. Aluminum alloy has low density, but relatively high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, and has excellent electrical conductivity, thermal conductivity and corrosion resistance. The main application areas of aluminum alloy are aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry.
Aluminum alloy with good mechanical properties and good thermal and electrical conductivity.
The traditional aluminum alloy casting technology has many defects. The defects in the production of cast aluminum alloys are mainly reflected in the following two aspects.
(1) The casting process will be accompanied by the formation of many defects, such as misalignment, size inconsistency, insufficient pouring, pores, slag inclusion, pinholes, etc. These defects cause the casting process to reject more than 15%.
(2) Due to the slow cooling rate in the casting process, the aluminum alloy grains usually grow abnormally and the segregation of alloy elements seriously affects the mechanical properties of the aluminum alloy. In addition, cast aluminum alloys have poor weldability during the application process, and are prone to defects such as collapse, thermal cracks, pores, and burn through. At the same time, aluminum oxidation and alloying elements burn and evaporate can lead to reduced weld performance. The current connection problem of aluminum alloy is also a bottleneck restricting its application.
The traditional casting molding process from ingot to machining to the final actual parts requires multiple processes to complete, and the material utilization rate is low. The material utilization rate of some complex parts is only about 10%, and the casting process is correct. The requirements of the mold are extremely high, and the small parts with high complexity cannot even be molded by the casting method. Therefore, the limitations of traditional forming processing methods such as casting in certain specific fields (aerospace parts, complex parts for automobiles, and special-shaped flow parts for mineral processing, etc.) have become increasingly obvious.
And 3D printing technology can specifically solve some of the defects exposed in the above casting process, and meet the molding processing requirements of special parts that are difficult or impossible to process in the casting process. With the acceleration of the industrialization process, people's requirements for the structure of aluminum alloy parts and the performance of castings are also increasing. The current development trend of aluminum alloy structural parts is the overall forming of complex-shaped structural parts and the intelligentization of the process flow. The rapid production and manufacturing of parts with complex shapes, precise dimensions, small and thin walls, and overall no margins will be the development direction of aluminum alloy parts processing in the future.

Aluminum alloy with good mechanical properties and good thermal and electrical conductivity.
The traditional aluminum alloy casting technology has many defects. The defects in the production of cast aluminum alloys are mainly reflected in the following two aspects.
Low melting point. Aluminum has a low melting point, so its 3D printing laser sintering temperature is much lower than other metal materials.
The density is low. Aluminum can be used to make light structures and is known as "flying metal". Therefore, the support required when printing objects is lower than other metal materials.
Can be strengthened. The strength of pure aluminum is not high, and it can be turned into aluminum alloy by adding various elements to increase its strength.
Good plasticity and easy processing. Aluminum can be drawn into tubes and filaments, and extruded into various profiles. There are also research reports on the use of aluminum materials for FDM printing.
