Phase field modeling of additive manufacturing in metals

Abstract eng:
Additive manufacturing, also known as the 3D printing, is rising popularity for the past few years due to its widely application in various areas. However, not enough emphasize is drawn to the microstructures of the “build” material, which is actually really significant to the property and performance of the product. In this paper, we showed that the phase field crystal (PFC) model could be applied to identify and predict the microstructures during the solidification of the metals in additive manufacturing. Using this model, we can control and optimize the process parameters for microstructures in order to get the desired materials that we need.
