3D printing technology (additive manufacturing) not only has certain requirements on the particle size, particle size distribution, oxygen content and impurity content of metal powder, but also puts forward higher requirements on the shape of the powder, which shows that the shape of the powder affects the additive manufacturing. A factor of product quality. How can the shape of the tungsten powder make the overall performance of the printed tungsten parts better?

According to different shapes, tungsten powder can be divided into spherical tungsten powder and polygonal tungsten powder. Although there is no essential difference in chemical properties between the two, the former is more suitable for 3D printing. This is mainly because the spherical powder has good fluidity and high tap density, and the powder is fed and spread evenly, which is beneficial to improve the density and uniformity of tungsten parts.

The shape of tungsten powder is not only affected by the morphology of raw materials such as tungsten oxide, but also by the preparation method, process parameters and other factors.
