What is 3d printed metal powder material? 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. Currently, the metal powders used by most 3D printers include stainless steel, aluminium alloy, cobalt chromium alloy, copper alloy, titanium alloy, and nickel alloy. Iron base alloy is engineering technology's most important and largest metal material. It is mainly used for forming complex structures and is widely used in aerospace, automobile, shipbuilding, machinery manufacturing and other industries. Currently, aluminium alloys used for metal 3D printing mainly include aluminium silicon AlSi12 and AlSi10Mg. Aluminium silicon 12 is a light additive used to produce metal powders with good thermal properties. The combination of silicon and magnesium makes aluminium alloy have higher strength and stiffness, making it suitable for thin walls and complex geometry, especially in applications with good thermal properties. Low weight Aluminum alloy is one of the industry's most widely used nonferrous metal structural materials, with low density, high specific strength, close to or better than high-quality steel, and good plasticity. The research shows that the aluminium alloy used for 3D printing can make the parts compact and fine. Its mechanical properties are comparable to or even better than those of castings. Compared with the traditional process parts, its quality can be reduced by 22%, but its cost can be reduced by 30%.
How to 3d print metal powder materials? Metal powder manufacturing is a basic aspect of powder metallurgy. Different methods to prepare metal powders include reduction, electrolysis, carbonyl decomposition, grinding, and atomization. The four most widely used methods for producing metal powders are solid reduction, electrolysis, chemical, and atomization. 11 Most manufacturers use electrolysis and reduction methods to produce elemental metal powders. However, they are not suitable for manufacturing alloy powders. However, the atomization method tends to overcome this limitation. Therefore, manufacturers use it to produce alloy powder.
Performance Requirements of 3D Printing on Metal Powder First, the purity of ceramic inclusions will significantly reduce the performance of the final part, and these inclusions generally have a high melting point and are difficult to sinter. Therefore, the powder must be free of ceramic inclusions. In addition, the oxygen and nitrogen content also need to be strictly controlled. The powder preparation technology used for metal 3D printing is mainly the atomization method. The powder has a large specific surface area and is easy to oxidize. In aerospace and other special applications, customers have more strict requirements on this indicator, such as the oxygen content of high-temperature alloy powder is 0.006% - 0.018%, that of titanium alloy powder is 0.007% - 0.013%, and that of stainless steel powder is 0.010% - 0.025% Secondly, powder flowability and loose density powder flowability directly affect the uniformity of powder spreading and the stability of powder feeding during printing The fluidity is related to the powder morphology, particle size distribution and bulk density. The larger the powder particles are, the more regular the particle shape is, and the smaller the proportion of extremely fine powder in the particle size composition is, the better the fluidity is; When the particle density is constant, the relative density and the powder fluidity increase. In addition, water and gas adsorbed on the particle surface will reduce the powder fluidity.
Price of 3d printed metal powder material 3d printed metal powder material particle size and purity will affect the product's price, and the purchase volume can also affect the cost of 3d printed metal powder.
