Fused filament fabrication (FFF), as a form of additive manufacturing (AM), in recent years, has become a popular method to manufacture prototypes, as well as functional parts. FFF is an extrusion process, commonly known as 3D printing, where the object is built by depositing melted material layer by layer. The most common materials, i.e., the materials that are most widely used, are polylactic acid (PLA), acrylonitrile butadiene styrene (ABS) and acrylonitrile styrene acrylate (ASA). Although there are lot of research papers that cover the subject of the determination of mechanical properties and characteristics, theoretically and experimentally, as well as the fatigue characteristics of aforementioned materials, there is a lack of research and scientific papers dealing with the problematics of S-N curves based on the rotating bending fatigue analysis of those materials. Consequently, this paper covers the topic of rotating bending fatigue data for 3D printed specimens of given materials, under different loading values.
熔融沉积成型（FFF）作为增材制造（AM）的一种形式，近年来已成为制造原型以及功能部件的常用方法。FFF是一种挤压工艺，通常称为3D打印，通过逐层沉积熔化的材料来构建物体。最常见的材料，即使用最广泛的材料，是聚乳酸（PLA）、丙烯腈-丁二烯-苯乙烯（ABS）和丙烯腈-苯乙烯-丙烯酸酯（ASA）。尽管有许多研究论文从理论和实验上涵盖了上述材料的力学性能和特性测定以及疲劳特性，但缺乏基于这些材料旋转弯曲疲劳分析的S-N曲线问题的研究和科学论文。因此，本文涵盖了给定材料的3D打印试样在不同载荷值下的旋转弯曲疲劳数据这一主题。
