Abstract
Additive manufacturing technologies are processes that are increasingly used in the aeronautical, biomedical, and automotive fields. These technologies have certain advantages over traditional manufacturing processes, one of these advantages being the possibility of obtaining highly complex geometries. Within these technologies we find FFF (fused filament fabrication) which is a material extrusion process.
The main objective of this work is the study of standardized PLA samples. Samples obtained from FFF additive manufacturing. Initially, a bibliographic search is carried out in order to understand this technology and the necessary regulations for tests. The samples are manufactured according to design of experiences and the stipulated regulations.
Subsequently, these samples are subjected to rotational bending fatigue tests. Obtaining curves that allow knowing the influence that the technology parameters have on the fatigue life of the samples. As well as a fractographic analysis of samples, to observe the crack propagation. The results are compared with previous available research that will serve as references.
