3D printing spherical powder is a 3D printing material, and its quality also determines the quality of the printed product to a certain extent. So we need to pay special attention when choosing to use.
1. 3D printing spherical powder without impurities
Once there are too many impurities in the 3D printing powder, the melting point of part of the powder will rise, resulting in incomplete dissolution during laser dissolution, resulting in unqualified printed products.

2. The size of the oxygen content
At present, the manufacturing method of 3D printing powder is mainly atomization, which makes the variable area of ​​the powder larger, so the oxidation phenomenon will be more serious. Therefore, we should pay close attention to the oxygen content in the powder.
3. Particle size of powder
The particle size of the 3D printing spherical powder has a great influence on the product pages formed. In general, the smaller the particle size of the powder, the better. The printed product not only has high precision, but also has a smooth surface. However, if the particle size is too small, spheroidization will occur due to uneven powder distribution during printing.
4. Powder shape
Generally speaking, 3D printed spherical powder is more suitable for printing, because 3D printed spherical powder has better fluidity and is easier to lay flat during printing, which can make the printed product look better. Otherwise, if the metal powder is not spread well, the surface of the printed product will appear rough.
