ABSTRACT: This paper investigates the effects of particles size and morphology on flowability of a range of
polymeric powders (SLS and non-SLS grades). The effect of additives incorporation, as well as drying or sieving,
on the flowability characteristics of the powders is also analyzed. The results show that the particle morphology
has a stronger influence on the
