    Description

    Metal Laser Powder Bed Fusion (PBF-LB/M) is a complex phenomenon that involves heat transfer, mass transfer, phase change, fluid flow, and other physics fields. In this research we are using ANSYS Fluent as thermal CFD software to setup and solve multiple physical field equations to model the process of PBF-LB/M. This developed computational model and analyze variations in input process parameters such as laser power, scan speed, beam diameter, and non material behavior. Considering all these input process parameter variations, it is possible to predict the melt pool dimensions, temperature distribution, liquid-gas interface with greater accuracy. In this research, we considered Inconel-718, to predict the melt pool morphology for varying process conditions. The predicted dimensions of the melt pool will be validated against well known NIST experimental dataset. Therefore, the developed fluent thermal-CFD will be presented as a high fidelity computational model to predict the process and structure of PBF-LB/M manufacturing systems.
