Additive Manufacturing Powders include, but are not limited to: Titanium, Aluminum, Cobalt Chrome, and Nickel. All of these are dense metal powders that tend to have spherical characteristics. This can lead to potential problems with sieving these powders due to the fact that spherical powders can lodge themselves in the square mesh opening which results in blinding. The dense metal powder can also quickly overload a screen if the material sits on the mesh for too long. Standard vibratory screeners normally require making cuts at sizes larger that the original powder spec in order to make efficient separations.
