摘要

3D打印是目前最具前景的技术之一。最近,3D打印取得了显著进展,有望在汽车、医疗、风力涡轮机和航空航天应用等众多应用中继续发展。3D打印技术为增强和优化几种应用打开了大门。尽管取得了这些进展,但在这一领域的摩擦学研究仍然缺乏。这项工作致力于研究3D打印聚合物(ABS, PLA, Co-polyester和PCL)的摩擦学性能,用于广泛的应用,如医疗,汽车和各种摩擦学应用。测试样品采用熔融沉积建模(FDM)技术打印。使用针盘式试验机对3D打印样品的摩擦学特性进行了评估。用维氏硬度计测定试样的硬度。采用后向散射扫描电镜(SEM)对试样的磨损表面进行了检测。根据目前的调查结果,发现3D打印技术提高了试件的粘接强度和耐磨性。此外,3d打印聚合物(ABS, PLA, Co-polyester和PCL)在可接受的耐磨性下产生不同的摩擦系数(高和低)值,使其适用于广泛的应用。PLA和共聚酯材料的摩擦系数最低(0.3),ABS和PCL材料的摩擦系数最高(0.4)和(0.39)。

Tribological Properties of 3D Printed Polymers: PCL, ABS, PLA and Co Polyester
3D printing is one of the most portentous technologies for the time being. Recently, 3D printing has progressed remarkably and is expected to proceed in numerous applications, such as automotive, medical, wind turbine, and aerospace applications. 3D printing technology opens the door to enhancing and optimizing several applications. Although of such advancement, there is still a lack of the tribological research investigations in this area. This work is devoted to studying the tribological properties of 3D printed polymers (ABS, PLA, Co-polyester, and PCL) for utilization in a wide range of applications, such as medical, automotive, and various tribological applications. The test specimens were printed using fused deposition modeling (FDM) technology. The tribological characteristics of 3D printed specimens were evaluated using a pin-on-disc tester. Vicker's hardness tester was used to determine the specimens' hardness. Scanning electron microscopy (SEM) with backscattering was used to examine the worn surfaces of samples. Based on the findings of the current investigation, it was discovered that 3D printing technology enhanced the bonding strength and wear resistance of the tested specimens. Furthermore, the 3D-printed polymers (ABS, PLA, Co-polyester, and PCL) produced varying friction coefficient (high and low) values at acceptable wear resistance making them suitable for a wide range of applications. The samples that were printed using PLA and co-polyester had the lowest coefficients of friction (0.3) while the samples that were printed using ABS and PCL had the greatest coefficients of friction (0.4) and (0.39) respectively.
