The microstructure and mechanical properties of additively manufactured metal parts are closely tied to the cooling rate and the temperature gradient direction during solidification. Traditionally, these properties have been modified by changing the scanning strategy. This study explores an alternative approach by varying laser speed and power while maintaining a consistent bidirectional meander scanning strategy, without rotating the following layers, in the fabrication of X30Mn22 austenitic steel. The aim of this paper was to determine whether different crystallographic textures could be achieved under these conditions and to assess their mechanical properties. The results confirm that variations in laser parameters can produce distinct microstructures with different grain shapes, sizes, and orientations. Furthermore, these structural differences were found to correspond with significant variations in mechanical properties, demonstrating the potential of this method for fine-tuning material characteristics in additive manufacturing.
