An important material used in 3D printing-metal powder
Titanium alloy, aluminum alloy, stainless steel, metal powder materials that can be used for 3D printing are really many printing consumables that are widely used in 3D printing, and mainly include four types: liquid photosensitive resin material, thin material, low melting point wire and powder Materials; in terms of composition, it almost covers all kinds of materials in current production and life, including plastics, resins, waxes and other polymer materials, metal and alloy materials, ceramic materials, etc. Among them, the most cutting-edge and most potential Undoubtedly, it is metal powder 3D printing. By 2024, the global market for metal powder additive manufacturing will reach 11 billion U.S. dollars.
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. It has low density, high specific strength, close to or exceeds high-quality steel, and good plasticity. 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.
