| Abstract Scope |
Powder-based additive manufacturing (AM) technologies are capable of producing high-performance parts for a diverse set of applications. Many AM processes, such as cold spray, require specific tolerances on the feedstock powder utilized in order to be successful, necessitating accurate and precise measurements of feedstock particle size distribution (PSD) and morphology. This study investigates the validity of several powder PSD and morphology measurement methods, including laser diffraction and image analysis techniques, for AM applications. Four AM powder specimens of varying size and shape were tested using different procedures at both the commercial and university research levels to compare the influence of data collection method on reported powder characteristics. Trends in PSD were further analyzed upon testing a blend of calibration standards with a fixed distribution. Results indicate differences between data procurement techniques, emphasizing the importance of how PSD and morphology are measured and interpreted in the context of AM. |
