Optimization of tensile strength of AlSi10Mg material in the powder bed fusion process using the Taguchi method

This study examined scan speed, hatch distance, and scan rotation angle parameters to determine the effects of the powder bed fusion process on the tensile strength of AlSi10Mg material. The Taguchi L9 experimental design was applied to evaluate the effects of the parameters systematically. The experimental results revealed the importance of the parameters affecting the tensile strength of the AlSi10Mg material. While the scan speed was determined to be the parameter that most affected the tensile strength with a contribution rate of 81.4%, the scan rotation angle and hatch distance were effective at 7.8% and 6.1%, respectively. In the optimization performed using signal/noise analysis, 1200 mm/s scan speed, 80 μm hatch distance, and 17° scan rotation angle were found to be the most suitable parameters to ensure the highest tensile strength. The tensile strength obtained in the verification test was measured at 598 MPa. The findings increase the application potential of SLM technology with AlSi10Mg material and provide valuable information for process optimization. The results can significantly contribute to strategies to increase tensile strength and improve material performance in industrial production processes.
