Therefore, metal powder is at the heart of metal 3D printing. The amount of tungsten powder in metal 3D printing is also very large, so what kind of quality is better for spherical tungsten powder? High-quality 3D printing spherical tungsten powder must have the following characteristics

1. High purity
The purity of the powder is more than 99.9%, and the potential risks caused by impurities in the use process have been well controlled.
2. High sphericity
The sphericity is above 90%, the satellite powder is less, the powder is not easy to overlap during the powder spreading process, the bulk density is high, and the printed parts are dense.
3. Low oxygen content
The oxygen content is controlled at a low level, which can allow the powder to be printed multiple times, and the oxygen content is still within the allowable range, reducing the cost of use.
4. Good liquidity
The powder spreads smoothly and is not easy to bridge, which improves the printing success rate for powder feeding equipment on large-size printers.
