Abstract Scope |
Are the fatigue properties the same for different metal additive manufacturing processes when using the same material? Many metal AM processes offer process parameters for the same alloys but the fatigue behavior can vary significantly. In this study, we are comparing the fatigue properties of specimens fabricated via different powder bed fusion (PBF) and binder jetting processes using 17-4 PH Stainless Steel. The fatigue testing is conducted using a rotating beam fatigue testing setup under four-point bending. The specimens from the different processes will be tested in the as built stage as well as with post finished surfaces. The fracture surfaces will be examined and compared. The microstructure of each sample will be examined and compared to the fatigue behavior. The goal of this study is to establish a better understanding of how different metal AM processes compare when it comes to fatigue behavior |
