What is 3D printing metal powder? Metal 3D printing is a 3D printing technology that uses metal powder to directly print metal parts, also known as metal powder sintering (SLM) In addition to good plasticity, 3D printing metal powder must also meet the requirements of fine particle size, narrow particle size distribution, high sphericity, good fluidity and high loose density At present, the metal powders used in most 3D printers include stainless steel, aluminum alloy, cobalt chromium alloy, copper alloy, titanium alloy and nickel alloy Iron base alloy is the most important and largest metal material in engineering technology. It is mainly used for forming complex structures and is widely used in aerospace, automobile, shipbuilding, machinery manufacturing and other industries
How to produce 3D printing metal powder? Metal powder manufacturing is a basic aspect of powder metallurgy Different methods for preparing metal powders include reduction, electrolysis, carbonyl decomposition, grinding and atomization The four most widely used methods for producing metal powder are solid state reduction, electrolysis, chemical method and atomization method
Most manufacturers use electrolysis and reduction methods to produce elemental metal powders. However, they are not suitable for making alloy powders. However, atomization tends to overcome this limitation, so manufacturers use it to produce alloy powders
Electrolysis is another method used to produce powdered metals By selecting appropriate electrolyte composition, temperature, concentration and current density, different metals can be deposited into sponge or powder. After that, washing, drying, reduction, annealing and crushing can be carried out. This method produces metal powder with very high purity. Because of its high energy demand, it is basically used for high conductive copper powder
The atomization method refers to the mechanical method to pulverize the molten metal into a size less than 150 μ M or so According to the way of smashing molten metal, atomization methods include two stream atomization, centrifugal atomization, ultrasonic atomization, vacuum atomization, etc. These atomization methods have their own characteristics and have been successfully applied in industrial production Among them, water vapor atomization has the advantages of simple production equipment and process, low energy consumption, large batch, etc., and has become the main industrial production method of metal powder
