In the field of Additive Manufacturing, Fused Filament Fabrication (FFF) is one of the methods used for prototyping and production applications. However, the performance of the printed parts produced can be affected by the various parameters used. The purpose of this research is to evaluate the bonding between layers of 3D printed parts from 3D printer by using Polylactic Acid (PLA) with printing parameters, namely printing temperature, printing speed and raster angle. The specimens were printed by using Monoprice Maker Select 3D printer. Compression test and fatigue test were carried out to determine the behavior of true stress-strain and the lifespan of sample subjected to cycling loading. The influence of printing temperature, printing speed and raster angle is determined by using Analysis of Variance (ANOVA). The results show that printing temperature affect the bonding between layers of samples more than the printing speed and raster angle.
