Abstract

This study investigated the influence of print orientation on the mechanical properties of 17-4 PH stainless steel parts fabricated using material extrusion technology. Tensile test specimens were 3D printed in different orientations (flat, on-edge, and upright), and their mechanical properties were evaluated. The results showed that the print orientation significantly affected the ultimate tensile strength, yield strength, and elongation at failure of the specimens. The flat and on-edge orientations exhibited similar mechanical properties, while the upright orientation resulted in lower strength and higher fracture susceptibility. Hardness measurements also indicated variations in hardness distribution among the orientations. The findings emphasize the importance of optimizing the print orientation parameter to achieve desired mechanical characteristics in 17-4 PH stainless steel parts.

材料挤压金属印刷中印刷方向对17-4不锈钢制品力学性能影响的研究

研究了打印方向对材料挤压成形17-4 PH不锈钢零件力学性能的影响。以不同方向(平面、边缘和直立)3D打印拉伸试件，并对其力学性能进行评估。结果表明，打印方向对试样的极限抗拉强度、屈服强度和断裂伸长率有显著影响。平面取向和边缘取向的力学性能相似，而垂直取向的强度较低，断裂敏感性较高。硬度测量也显示了不同取向间硬度分布的变化。研究结果强调了优化打印方向参数以实现17-4 PH不锈钢部件所需机械特性的重要性。
