3D printing represents a revolutionary new form of printing technology. For 3D printing metallic parts, 3D printing powder is the best raw material. The main 3D printing powders are currently nickel-titanium alloy powder Steel, nickel-aluminum, alloy, industrial steel and cobaltchromium alloy.
Good plasticity is required for 3D printing metal powder. This powder must meet the following requirements: small powder size distribution, fine powder particle size distribution and good flow.

Three types of preparation for 3D printing metallic powder are available: reduction, electrolysis and grinding. The most common pulverizing process in China is the argon atomization or plasma rotating electrode methods.

1. Argon atomization
An argon atomization is a process that makes powder by using the fast flowing, argon gases flow. This method uses the impact of the metal liquid to break it into fine particles. Then, the solid powder can be condensed.

2. Plasma rotating electrode technique
Plasma state can be described as the fourth state. You can simply describe the plasma rotating electrode atomization process (prep method) as follows: After the metal or alloy is made, the plasma melts at the coaxial plasma-arc heating source to create liquid film. Next, the rotating centrifugal force forces the liquid droplets to separate from the gas in the chamber. Under the shear stress, the droplets cool and become spherical powder.

Here are some of the benefits that metal powder created by plasma rotating electro method:

Smooth surface, high sphericity with high loose density and smooth surface. This powder is ideal for printing because it is very consistent and reliable.
