The main objective of this study is to characterize the effect of infill percentage, printing orientation and raster angle on ABS samples prepared with 3D printing technology. In this research, samples used were fabricated with two different infill percentages (50% & 75%), 6 different raster patterns and three different orientations. The influence of these parameters on tensile properties were studied with the help of 3D printed samples as per ASTM standard D638 Type IV. From the experimental analysis it was found that the tensile properties were highly anisotropic. Stress strain graphs are plotted for all the samples and the variation of strength with respect to the three parameters are analysed. It was observed that Infill density is directly proportional to mechanical properties. Flat and vertical orientation have better strength and stiffness in comparison with vertical build. The experimental results proved that flat oriented samples exhibited variable strength for chan...

研究取向，填充密度和三重光栅图案对3D打印样品的拉伸性能的影响

这项研究的主要目的是表征填充百分比，打印方向和光栅角度对用3D打印技术制备的ABS样品的影响。在这项研究中，所使用的样品以两种不同的填充百分比（50％和75％），6种不同的光栅图案和三种不同的方向制造。根据ASTM标准D638 Type IV，借助3D打印样品研究了这些参数对拉伸性能的影响。从实验分析中发现，拉伸性能是高度各向异性的。绘制了所有样品的应力应变图，并分析了强度相对于三个参数的变化。观察到填充密度与机械性能成正比。与垂直构建相比，平面和垂直方向具有更好的强度和刚度。实验结果证明，平板取向的样品在测试过程中表现出不同的强度。
