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.
本研究考察了扫描速度、扫描间距和扫描旋转角度参数，以确定粉末床熔融工艺对AlSi10Mg材料拉伸强度的影响。采用田口L9实验设计系统地评估这些参数的影响。实验结果揭示了影响AlSi10Mg材料拉伸强度的参数的重要性。扫描速度被确定为对拉伸强度影响最大的参数，贡献率为81.4%，而扫描旋转角度和扫描间距的贡献率分别为7.8%和6.1%。在使用信号/噪声分析进行的优化中，发现1200毫米/秒的扫描速度、80微米的扫描间距和17°的扫描旋转角度是确保最高拉伸强度的最合适参数。验证试验中获得的拉伸强度测量值为598兆帕。这些发现增加了SLM技术在AlSi10Mg材料上的应用潜力，并为工艺优化提供了有价值的信息。研究结果可为提高工业生产过程中拉伸强度和改善材料性能的策略做出重大贡献。
