Direct-Powder Bed Selective Laser Processing (PBSLP) is considered a promising technique for Additive Manufacturing of Alumina. The process parameters are considered the key for a successful PBSLP of Alumina and needed to be investigated and optimized. In this study, different scanning strategies such as concentric out-in, zigzag, and island have been studied experimentally and numerically. The numerical model was used to determine the suitable process parameters. In terms of relative density, island strategies achieved relative density reached 70% of the theoretical density, with a 16% improvement over other strategies. Also, the Island strategy gave dimensional integrity better than the other strategies with a surface roughness of 0.125 mm measured on the top surface. It can be concluded that the island strategy is more effective in the PBSLP of Alumina. The results from this study will be considered for studying the effect of other process parameters s in a coming study.
