How to Produce Metal Powder for 3D Printing

The U.S. and its allies plan to impose sanctions on more Russian industries and supply chains.

The US government representatives recently visited Europe to consult with allies on strengthening and enforcing sanctions to punish Russia. They also plan to take action to disrupt their critical supply chains.

The US government claims that the sanctions imposed on Russia since the invasion began on February 24 have proved extremely effective, plunging Russia into a financial crisis. The sanctions include a freeze on the Russian central bank's foreign exchange assets, a ban on hard currency transactions by major Russian banks and wealthy individuals, and export restrictions on advanced semiconductors and other technologies. The sanctions have weakened the Russian economy and left the Kremlin with fewer resources.

The volatile international political situations will continue to affect the markets and prices of many commodities like the Metal Powder.


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.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the Metal Powder will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of Metal Powder.
