This study utilizes a hatching strategy based on displacement simulation results to significantly reduce such displacements. The residual displacements for specific geometries and materials were determined using the inherent strain method. Subsequently, the hatching vectors were planned orthogonally to the simulated displacement vectors. The findings indicate that aligning the hatching orientation based on simulation results decreased the displacement by up to 70%, in propeller blades made of AlSi10Mg. This approach displays the potential for enhancing the precision and stability of PBF-LB/M processes.
