Abstract

In this study, a novel flexural fatigue testing apparatus was designed to evaluate the fatigue behavior of 3D-printed materials. The machine was validated using polylactic acid (PLA) 3D-printed samples and fiber-reinforced thermoformed polypropylene (PP). The investigation focused on the effects of varying infill percentages of PLA and fiber reinforcement in PP under constant deflection, in accordance with Newton’s third law. The results provided significant insights into the fatigue life of these materials, including stiffness degradation and damage accumulation, thereby confirming the machine’s efficacy. This research contributes to a deeper understanding of 3D-printed material behavior under cyclic loading and enhances the machine’s capability to assess both conventional and specialized plastics. Furthermore, we compared the indirect measurement of elastic modulus obtained from fatigue testing with direct measurements for various percentages of reinforced PP, demonstrating the feasibility of deriving elastic modulus from fatigue testing.

设计用于表征 3D 打印材料的挠曲疲劳机：利用牛顿第三定律的方法

本研究设计了一种新型挠曲疲劳测试仪器，用于评估 3D 打印材料的疲劳行为。使用聚乳酸（PLA）3D 打印样品和纤维增强热成型聚丙烯（PP）对该仪器进行了验证。研究重点是根据牛顿第三定律，在恒定挠度条件下，聚乳酸和纤维增强聚丙烯中不同填充百分比的影响。结果对这些材料的疲劳寿命（包括刚度退化和损伤累积）提供了重要启示，从而证实了机器的功效。这项研究有助于更深入地了解三维打印材料在循环加载下的行为，并增强了机器评估传统塑料和特种塑料的能力。此外，我们还比较了从疲劳测试中获得的弹性模量间接测量值和不同百分比的增强聚丙烯的直接测量值，证明了从疲劳测试中推导弹性模量的可行性。
