Fused Deposition Modelling (FDM) is one of the layer-based technologies that fall under the umbrella term "Additive Manufacturing", where the desired part is created through the successive layer-by-layer addition process with high accuracy using computer-aided design data. Additive manufacturing technology, or as it is commonly known, 3D (three-dimensional) printing, is a rapidly growing sector of manufacturing that is incorporated in automotive, aerospace, biomedical, and many other fields. This work explores the impact of the Additive Manufacturing process on the mechanical proprieties of the fabricated part. To conduct this study, the 3D printed tensile specimens are designed according to the ASTM D638 standards and printed from a digital template file using the FDM 3D printer Raise3D N2. The material chosen for this 3D printing parameter optimization is Polylactic acid (PLA). The FDM process parameters that were studied in this work are the infill pattern, the infill density, and the infill cell orientation. These factors' effects on the tensile behavior of printed parts were analyzed by the design of experiments method, using the statistical software MINITAB2020.
熔融沉积建模（FDM）是属于“增材制造”这一统称的基于层的技术之一，在增材制造中，使用计算机辅助设计数据通过逐层层叠添加的高精度过程来创建所需部件。增材制造技术，或者通常所说的3D（三维）打印，是制造业中一个快速发展的领域，已应用于汽车、航空航天、生物医学等许多领域。这项工作探讨了增材制造工艺对所制造部件机械性能的影响。为进行这项研究，根据ASTM D638标准设计3D打印拉伸试样，并使用FDM 3D打印机Raise3D N2从数字模板文件进行打印。用于此3D打印参数优化的材料是聚乳酸（PLA）。在这项工作中研究的FDM工艺参数是填充图案、填充密度和填充单元取向。使用统计软件MINITAB2020，通过实验设计方法分析了这些因素对打印部件拉伸行为的影响。
