The printing consumables widely used in 3D printing mainly include four types in terms of form: liquid photosensitive resin materials, thin materials, low melting point wire materials and powder materials; in terms of composition, they almost cover all kinds of materials in current production and life. , including polymer materials such as plastics, resins, and waxes, metal and alloy materials, ceramic materials, etc. Among them, metal powder 3D printing is undoubtedly at the forefront and has development potential.
Currently, 3D printing metal powder materials include stainless steel, mold steel, nickel alloy, titanium alloy, cobalt-chromium alloy, aluminum alloy and bronze alloy.
1. Argon atomization method
Argon atomization powder making is a powder making method that uses fast-flowing argon gas flow to impact metal liquid, break it into fine particles, and then condense into solid powder.
2. Plasma atomization method
The plasma atomization powder making process can be simply described as: solid raw materials, such as rods and wires, are directly fed into the plasma focus high-temperature area through a dedicated feeding device. The raw materials are rapidly melted or vaporized or decomposed and synthesized by thermal reaction. , atomize to prepare ultra-fine/nano-scale metal or ceramic powder materials of various materials, and then the molten droplets are rapidly cooled and solidified into spherical powder under the action of surface tension. The prepared powder materials are cooled and deposited in the atomization tower system, and concentrated collect. The atomized exhaust gas is filtered and purified before being discharged.
