3D printing technologyis a revolutionary type of printing technology. The key advantage of this new technology is the ability to directly create parts in any shape using computer graphics data. It can also be used without any machining and molds. This allows for faster product development, increased productivity and lower production costs. The most popular raw material to 3D print metal parts has been 3D printing powder. 3D printing metallic powder is the most significant part of 3D printing.
Metal powder preparation
The current metal powder preparation techniques can be classified into one of the following categories: electrolysis, reduction, or carbonyl decomposition. The preparation method is what determines the final product. Powders made by electrolysis, reduction and atomization are the most commonly used as raw materials in the powder metalurgisty industry. You can use the atomization method to make alloy powder. Modern atomization processes can even control the powder shape. Continuous improvement of the atomization cavity structure is a significant factor in improving the atomization efficiency. The atomization method has gradually evolved into the main powder manufacturing method. 3D printing requires a specific atomization method. A mechanical process that pulverizes molten metal to produce small particles of less than 150mm is called the atomization technique.
Water atomization
Water atomization is one method that can be used to produce atomized dust. Water atomization medium is both cheap and simple to get, but it also has excellent atomization performance. The domestic water atomization process is currently used to create steel powder and matrix for diamond tools. It also produces pre-alloy and oil-bearing bearings and powder for hard surfaces technology. Because water’s specific heat is greater than the capacity of gases, when the powder is atomized, broken metal particles can solidify quickly, becoming irregular and affecting the powder’s sphericity. Water can react with other alloys and metals which have high activity. In addition, powders with high activity will react to water. These issues limit water atomization when preparing metal powders having high sphericity but low oxygen.
