Metal powder materials for 3D printing include stainless steel, die steel, nickel alloy, titanium alloy, cobalt-chromium alloy, aluminum alloy and bronze alloy. Iron base alloy is the most important and largest metal material in engineering technology. It is widely used in the forming of complex structures and is widely used in aerospace, automobile, shipbuilding, machinery manufacturing and other industries. Read More »

In addition, oxygen and nitrogen content also need to be strictly controlled. In aerospace and other special application fields, the purity requirements are more strict, such as the oxygen content of superalloy powder is 0.006% ~ 0.018%, titanium alloy powder is 0.007% ~ 0.013%, stainless steel powder oxygen content is 0.010% ~ 0.025% (all are mass fraction).

The preparation methods of metal powder can be divided into reduction method, electrolysis method, grinding method, atomization method and so on. At present, argon atomization and plasma rotating electrode are the two most advanced pulverizing processes in China. Argon atomization powder making method is to use the fast flowing argon flow to impact the metal liquid, break it into fine particles, and then condense into solid powder. Read More »

Titanium alloy, aluminum alloy, stainless steel, there are a lot of metal powder materials that can be used for 3D printing. There are four kinds of printing consumables widely used in 3D printing: liquid photosensitive resin material, thin material, low melting point silk material and powder material. Read More »
