High-quality spherical metal powder is an important guarantee for high-performance metal additive manufacturing. Its composition, oxygen content and powder physical properties (morphology, particle size distribution, powder fluidity, loose density, etc.) have an impact on the stability and manufacturing process of 3D printing. The physical and chemical properties of the parts are very important, affecting and determining whether the product can be installed and applied.

Among the many technical indicators of powder, the sphericity of the powder and the ratio of satellite spheres directly affect the fluidity and bulk density of the powder. Low powder sphericity or too high proportion of satellite spheres will directly affect the powder feeding or spreading quality, which in turn affects the quality of printed parts, and produces internal and surface defects. In recent years, with the increasing maturity of additive manufacturing technology, the demand for efficient forming of complex components and large parts has become higher and higher. Smart additive manufacturing factories have also emerged, but they are limited by the bottom-mounted powder supply mode in equipment operation. In the process, it is impossible to add powder online, and the opening and adding powder is prone to step connection and metallurgical defects. Therefore, the international mainstream large-size equipment usually adopts the continuous powder feeding system of the upper feeding type. The upper powder feeding method requires high powder fluidity. If the powder fluidity is not good and the powder falls unevenly, or there is agglomeration or unevenness in the powder spreading process, the printing quality will be adversely affected. In the future, the demand for high fluidity powders in metal additive manufacturing will become more and more prominent.


Aluminum alloy powder is not easy to obtain high fluidity due to its light density, and the morphology control of the preparation of aluminum alloy powder is more difficult than other alloy materials, so that for a long period of time, the aluminum alloy powder for 3D printing only has an angle of repose. Evaluate powder fluidity, but can not be directly measured with a Hall flow meter. In 2020, KMPASS launched a series of high-fluidity aluminum-based alloy powder materials optimized for metal additive technology. The powder has high sphericity and good fluidity, which further breaks through the poor fluidity and low loose density of aluminum alloy powders in the past. And other technical problems. At present, the company's high-fluidity aluminum-based alloy powder materials (AlSi10Mg, etc.) have been used in aerospace, automotive and transportation fields in batches, and the powder product characteristics and printed parts have good performance.
