(Batch Application of 3D Printing Aluminum Alloy Powder)

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, 3dprintingpassion 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.
