Fused Deposition Modeling (FDM), is one of the most popular and widely used Additive Manufacturing filament based technology employing materials such as Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Thermoplastic Polyurethane (TPU) and Polylactic Acid (PLA). In this technique, the part is built up layer-by-layer, affecting, both the resolution along the z-axis, and the mechanical properties dependent on the mesostructure, controlled by a large amount of production parameters such as layer thickness, raster orientation, number of contour and air gap. When dealing with functional and structural printed parts, a deep understanding of these tunable building parameters and their influence on the mechanical properties is of the utmost importance and over the years many experimental studies have been carried to investigate this need. This study is intended to explore specimens realized through FDM technique with different combinations of printing parameters to analyse their effect on the mechanical properties of ABS Plus p430. To this aim, tensile and compression specimens, had been designed and tested. Sixteen different types of tensile specimen had been realized by varying four different parameters, namely, layer thickness, part interior style, infill orientation and number of contours. Whereas, the number of compression specimens had been limited to four considering the variation of two parameters: layer thickness and part interior style. Three samples for each specimen had been produced in ABS Plus p430 using a Stratasys Fortus 250mc FDM printer and tested with a universal testing machine through tension and compression tests to analyse the correlation between printing parameters and material properties. Test results had led to important conclusions on the consistency and homogeneity of the mechanical properties and on the variation of the material’s performances in accordance with the different combinations of production parameters.

熔融沉积成型 (FDM) 是最流行和广泛使用的基于增材制造长丝的技术之一，采用丙烯腈丁二烯苯乙烯 (ABS)、聚碳酸酯 (PC)、热塑性聚氨酯 (TPU) 和聚乳酸 (PLA) 等材料。在这种技术中，零件逐层构建，影响沿 z 轴的分辨率和依赖于细观结构的机械性能，受大量生产参数（如层厚度、光栅方向）的控制、轮廓数和气隙数。在处理功能性和结构性打印部件时，深入了解这些可调建筑参数及其对机械性能的影响至关重要，多年来，已经进行了许多实验研究来调查这一需求。本研究旨在探索通过 FDM 技术实现的具有不同印刷参数组合的样品，以分析它们对 ABS Plus p430 机械性能的影响。为此，设计并测试了拉伸和压缩试样。通过改变四个不同的参数，即层厚度、部件内部样式、填充方向和轮廓数量，已经实现了 16 种不同类型的拉伸试样。然而，考虑到两个参数的变化，压缩试样的数量被限制为四个：层厚度和部件内部样式。每个样品的三个样品使用 Stratasys Fortus 250mc FDM 打印机在 ABS Plus p430 中生产，并使用万能试验机通过拉伸和压缩测试进行测试，以分析打印参数与材料特性之间的相关性。测试结果得出了关于机械性能的一致性和均匀性以及材料性能根据生产参数的不同组合而变化的重要结论。
