Abstract Scope |
In this study, powder characterization will be extended to evaluate the effects of Particle Size and Distribution, and Particle Morphology on powder spreading process. The study will also characterize powder flowability using measurements of shear strength, angle of repose, and Hausner ratio. Resulting from flowability investigation, we plan to relate flowability function to the angles of repose, and to recommend critical particle size for acceptable flow. Thus, we should be able to determine what powder characteristics make good, reliable powder spread, recommend critical particle size for acceptable flow, provide parameters used as good indicators of powder flowability. Also, we should be able to determine the variability of powders; characteristics of recycled powder; effect of fine particles in mixtures; and correlate powder properties with the mechanical properties of AM parts. The second part of the study involve quantitative studies and comprehensive theoretical insights into the particle property effects on powder flowability. |
