| Abstract: | Laser Powder Bed Fusion (LPBF) is a three-dimensional printing method that could manufacture high-value, low-volume, and net shape parts. Therefore, the method is expected to partially replace some of the existing additive manufacturing processes for high-tech engineered products with its capabilities. Furthermore, LPBF is known for the capability of producing complex geometries without much cost. There are two challenges of LPBF. The challenge that this project focuses on is to obtain good and reproducible part properties from LPBF. Experiments can be used to find the optimal values of the process parameters that matter the most for the parts' quality but it is costly to be repeated. Therefore, numerical simulations can be helpful to reduce the cost. In this project, OpenFOAM was used to build and execute simulations. A numerical simulation in the solid domain was made to understand heat conduction. The results were accurate in its temperature dynamics. Furthermore, A numerical simulation that was built on a solver called laserbeamFoam was utilized for the LPBF process. The results show deformation in the powder bed due to the laser heat source. |
