5.1 Particle characterization, especially particle size distribution, has been an important parameter for quality control (QC) and research and development (R&D) in a very wide variety of industries and markets, anywhere a particulate system is a final product or an intermediate constituent somewhere in the process. But size alone is not a sufficient morphological measurement to use to understand many factors of the complete particle morphology of particulate systems and their effects on other properties. This information is expected to contribute to the understanding of the effects of shape on powder spreadability and flowability in the creation of the bed in powder bed fusion AM and the density and porosity of the final AM parts (definitions in ISO/ASTM 52900 and Terminology B243). Ultimately, specifications can be developed for quality control (QC) tolerances for these shape parameters that can be measured with a straightforward, fast automated analysis
