Selective Laser Melting (SLM) is a promising technique for the additive manufacturing (AM) of alumina; however, for the technique to be successful, the process parameters should be exhaustively investigated and chosen. Process parameters include laser power, scanning speed, hatching space, and scanning strategies. This study focuses on laser power, scanning speed, and hatching space, as the effect of scanning strategies, was already investigated in a previous study. Using the previously developed numerical model, initial predictions of laser power and hatching space at different scanning speeds of 100, 200, 300, and 400 mm/s were generated. The output of the numerical model was then experimentally examined. Using a scanning speed of 400 mm/s was able to achieve a relative density that was 84.2 % greater than other scanning speeds, as well as overcome other obstacles encountered by other scanning speeds. After optimising the process parameters, it was found that a scanning speed of 400 mm/s, a laser power of 210 W, and a hatching space of 30 µm could produce a relative density of 94.5 %. Evaluation of mechanical performance revealed that the microhardness of the printed alumina samples was comparable to that described in the literature. In contrast, the obtained compressive strength of 140 MPa was significantly lower than that described in the literature.
