Currently, 3D printing metal powder materials include stainless steel, die steel, nickel alloys, titanium alloys, cobalt-chromium alloys, aluminum alloys and bronze alloys.

Iron-based alloys are the most important and most used metal materials in engineering technology. They are mostly used for forming complex structures, such as stainless steel for 3D printing. Compared with traditional casting and forging technology, it has high strength, excellent high temperature resistance and wear resistance. It has physical, chemical and mechanical properties such as corrosion resistance, and has high dimensional accuracy and material utilization. It is widely used in aerospace, automotive, shipbuilding, machinery manufacturing and other industries.

Titanium alloy has excellent strength and toughness, combined with corrosion resistance, low specific gravity and biocompatibility, making it ideal for many high-performance engineering applications in aerospace and automotive competitions. It is also used in the production of biomedical implants, high, low modulus, strong fatigue resistance.


Cobalt-chromium alloys are commonly used in surgical implants such as alloy artificial joints, knee joints and hip joints due to their high wear resistance, good biocompatibility, and nickel-free (nickel content <0.1%), as well as engine parts , Wind turbines and many other industrial components.

Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. Its density is low, its specific strength is higher, it is close to or exceeds that of high-quality steel, and its plasticity is good. Studies have shown that aluminum alloys for 3D printing can achieve dense parts, fine structures, and mechanical properties comparable to castings or even better than casting molded parts. Compared with traditional process parts, their quality can be reduced by 22%, but the cost can be reduced by 30%. 

Copper alloys have excellent thermal and electrical conductivity. Copper with excellent thermal conductivity in thermal management applications can combine design freedom to produce complex internal structures and conformal cooling channels.
The metal powder preparation methods can be divided into: reduction method, electrolysis method, grinding method, atomization method, etc. according to the preparation process. At present, the two most advanced powder making processes commonly used in China are the argon atomization method and the plasma rotating electrode method.
