3D打印已被各行业公认为未来的制造技术。使用这种技术制造的产品的性能取决于许多因素，其中印刷方向是最重要的因素之一。目前，对于打印组件的构建方向没有标准。迄今为止，材料性能的分析是通过测试以不同方向打印的样品来进行的。本工作探讨了层取向对SLA制造的聚合物材料的不同机械性能的影响。使用五种不同的取向，即0度、22.5度、45度、67.5度和90度来打印样本，以分析材料的机械性能。拉伸、压缩、弯曲、冲击、疲劳和振动分析是根据各自标准进行的不同机械测试。据发现，印刷方向起着显着的作用，在各自的机械性能的行为。分别以22.5度和67.5度的角度打印的样本获得最大拉伸和压缩载荷。以67.5度取向打印的样品再次具有最高的弯曲强度，而以0度打印的样品具有更高的冲击和疲劳强度。
3D printing has been recognized as the future manufacturing technique by different industries. The properties of products manufactured using this technique depend upon large number of factors, with print orientation being one among the most important factors. Currently, there is no standard for the build orientation of the printed component. To date, the analysis of material properties is conducted by testing specimens printed in different orientations. The present work explores the effect of layer orientations on the different mechanical properties of an SLA manufactured polymer material. Five different orientations, i.e. 0 degrees, 22.5 degrees, 45 degrees, 67.5 degrees and 90 degrees were used to print the specimens for the analysis of mechanical properties of the material. Tensile, compression, flexural, impact, fatigue and vibration analysis are the different mechanical tests that were conducted as per their respective standards. It was found that the print orientation plays a significant role in the behaviour of the respective mechanical property. The maximum tensile and compressive load are being taken by the specimens printed at an angle of 22.5 degrees and 67.5 degrees, respectively. The specimen printed at 67.5 degrees orientation again have highest flexural strength, whereas the specimen printed at 0 degrees have higher impact and fatigue strength.
