Abstract

Purpose The purpose of this study, most recent advancements in threedimensional (3D) printing have focused on the fabrication of components. It is typical to use different print settings, such as raster angle, infill and orientation to improve the 3D component qualities while fabricating the sample using a 3D printer. However, the influence of these factors on the characteristics of the 3D parts has not been well explored. Owing to the effect of the different print parameters in fused deposition modeling (FDM) technology, it is necessary to evaluate the strength of the parts manufactured using 3D printing technology. Design/methodology/approach In this study, the effect of three print parameters − raster angle, build orientation and infill − on the tensile characteristics of 3D-printed components made of three distinct materials − acrylonitrile styrene acrylate (ASA), polycarbonate ABS (PC-ABS) and ULTEM-9085 − was investigated. A variety of test items were created using a commercially accessible 3D printer in various configurations, including raster angle (0°, 45°), (0°, 90°), (45°, −45°), (45°, 90°), infill density (solid, sparse, sparse double dense) and orientation (flat, on-edge). Findings The outcome shows that variations in tensile strength and force are brought on by the effects of various printing conditions. In all possible combinations of the print settings, ULTEM 9085 material has a higher tensile strength than ASA and PC-ABS materials. ULTEM 9085 material’s on-edge orientation, sparse infill, and raster angle of (0°, −45°) resulted in the greatest overall tensile strength of 73.72 MPa. The highest load-bearing strength of ULTEM material was attained with the same procedure, measuring at 2,932 N. The tensile strength of the materials is higher in the on-edge orientation than in the flat orientation. The tensile strength of all three materials is highest for solid infill with a flat orientation and a raster angle of (45°, −45°). All three materials show higher tensile strength with a raster angle of (45°, −45°) compared to other angles. The sparse double-dense material promotes stronger tensile properties than sparse infill. Thus, the strength of additive components is influenced by the combination of selected print parameters. As a result, these factors interact with one another to produce a high-quality product. Originality/value The outcomes of this study can serve as a reference point for researchers, manufacturers and users of 3D-printed polymer material (PC-ABS, ASA, ULTEM 9085) components seeking to optimize FDM printing parameters for tensile strength and/or identify materials suitable for intended tensile characteristics.
使用基于挤压的 3D 打印技术研究改变打印条件对拉伸特性的影响
本研究的目的:三维(3D)打印技术的最新进展主要集中在部件的制造上。在使用三维打印机制造样品时,通常会使用不同的打印设置(如光栅角度、填充和方向)来提高三维部件的质量。然而,这些因素对三维部件特性的影响还没有得到很好的探讨。由于熔融沉积建模(FDM)技术中不同打印参数的影响,有必要对使用三维打印技术制造的部件的强度进行评估。在本研究中,研究了光栅角度、构建方向和填充这三个打印参数对丙烯腈-苯乙烯-丙烯酸酯(ASA)、聚碳酸酯-ABS(PC-ABS)和 ULTEM-9085 这三种不同材料制成的三维打印部件的拉伸特性的影响。使用市售的 3D 打印机以不同的配置创建了各种测试项目,包括光栅角度(0°、45°)、(0°、90°)、(45°、-45°)、(45°、90°)、填充密度(实心、稀疏、稀疏双密度)和方向(平面、边缘)。在所有可能的印刷设置组合中,ULTEM 9085 材料的拉伸强度都高于 ASA 和 PC-ABS 材料。ULTEM 9085 材料的边缘取向、稀疏填充和光栅角度(0°,-45°)使其总体抗拉强度最大,达到 73.72 兆帕。ULTEM 材料的最高承重强度也是通过相同的程序达到的,为 2,932 牛顿。材料的边缘抗拉强度高于平面抗拉强度。三种材料的抗拉强度在实心填充的平整方向和光栅角为(45°, -45°)时都是最高的。与其他角度相比,三种材料在光栅角为(45°,-45°)时都显示出更高的抗拉强度。稀疏双密度材料比稀疏填充材料具有更强的拉伸性能。因此,添加剂成分的强度受到所选打印参数组合的影响。原创性/价值本研究成果可作为三维打印聚合物材料(PC-ABS、ASA、ULTEM 9085)部件的研究人员、制造商和用户优化 FDM 拉伸强度打印参数和/或确定适合预期拉伸特性的材料的参考点。
