Metal additive manufacturing (AM) processes allow the creation of complex, cutting-edge, and never-before-seen designs using a wide range of alloys. With an array of readily available AM technologies at their disposal, manufacturers are now focused on material development and processing to ensure the quality of their built components. Characterization of the powders used in many AM processes is a critical part of this effort, and includes analysis of particle density, flow, morphology, size, and thermal properties. Powders that are found to be unsuitable for a given AM process and application can then be processed to improve characteristics such as flowability, density, and purity.
