10/04/2017 · Particles with a size range of 50 to 1500μm are measured by this method. The size of particles is expressed as d seive which is the diameter of the sphere that passes through the sieve aperture. This is a rough and fast method and one can obtain weight distribution of particle sizes. Sieves of different pore sizes are used to sieve the powder.

Powder particle sizes have a direct influence on the layer thickness and minimum feature size of an AM part. Smaller powder particles permit a thinner layer thickness, finer minimum feature size and better surface finish. After a sample was collected the powder size distribution can be determined using one of the several methods mentioned below:
