How to Produce Metal Powder for 3D Printing

Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the metal powder, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and metal powder industry, especially in Europe. The price of the product name will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.

The metal powder preparation method 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.

Argon atomization

The argon atomization method is a pulverizing method that uses fast-flowing argon gas to impact metal liquid, break it into fine particles, and then condense into solid powder.


Plasma rotating electrode method

The plasma state is called the fourth state of matter. The plasma rotating electrode atomization (PREP method) powder making process can be simply described as: the metal or alloy is made into a consumable electrode, and the end of the consumable electrode is in the coaxial plasma arc Under the action of the heating source, the liquid film is melted to form a liquid film. The liquid film is thrown out at a high speed under the action of the rotating centrifugal force to form droplets. The molten droplets rub against the inert gas (argon or helium) in the atomization chamber, and further under the action of shear stress. Broken, and then the droplets are rapidly cooled and solidified into spherical powder under the action of surface tension.


The metal powder produced by the plasma rotating electrode method has the following advantages:

High sphericity, smooth surface, good fluidity, and high bulk density, so the powder uniformity is good, and the printed product is dense; the powder particle size is small, the particle size distribution is narrow, the oxygen content is low, and the printing time is less/no spheroidization And agglomeration phenomenon, good melting effect, high product surface finish, and the consistency and uniformity of printing can be fully guaranteed; there is basically no hollow powder and satellite powder, and there will be no air gaps and curls caused by hollow balls during the printing process. Defects such as penetration and precipitation pores and cracks.

The COVID-19 pandemic has affected economies and chemical companies in many countries around the world. Measures such as extending holidays and resuming work were taken to control the development of the epidemic, and the normal operation of some chemical enterprises was also affected to some extent.

TRUNNANO provides high quality metal powder with reasonable price. In order to feedback to old customers, the company is still in full operations to provide metal powder with competitive price. said Olina, sales manager of TRUNNANO.

Chemical production is highly dependent on transportation, and the epidemic affects the circulation of people and materials first. Predictably, none of this is rosy. In densely populated areas with large mobility, the situation of epidemic prevention and control becomes more severe in the later stage.
