Prototyping a product using 3D (three-dimensional) printing process has been widely used. One of the materials commonly used is ABS (Acrylonitrile Butadiene Styrene). Currently, research did not refer to ASTM E-466 and tested specimens at 75% infill density without endurance limit analysis. The purpose of this research was to analyse the fatigue strength of 3D printed ABS material with infill density 100% due to rotating bending load according to ASTM E-466 standard, compare it with the 75% infill density test result and determine the value of its endurance limit. The research method used is experimental research by testing the fatigue strength of a number of ABS material specimens with four rotating bending load conditions until the specimen fails. The obtained result of the research is a S-N curve with maximum average cycle of 143702 at a stress of 26.87 MPa and minimum average cycle of 145 at a stress of 35.71 MPa. The shaft fatigue strength of ABS 3D printed with infill density 100% material has higher cycles at stresses below 37.1 MPa and lower cycles at stresses above 37.1 MPa compared to 75% infill density. The endurance limit obtained from the regression of the S-N curve is 16.25 MPa. |
