AM Particle Size

One of the most critical attributes for control, particle size is essential to the AM process. Particle size distribution has a direct influence on powder flowability and the ability to provide a uniform, powder bed density. This in turn determines the energy input needed to process the powder grains and also affects the surface finish. Laser diffraction is the most accepted analytical technique utilized for the determination of particle size and particle size distribution.

Micromeritics Saturn DigiSizer© II employs a laser diode and modern charge-coupled device (CCD) detector to significantly improve the sensitivity, resolution, reproducibility and repeatability of the laser light scattering particle sizing technique.
