Fatigue Behaviour Evaluation of Additively and Conventionally Produced Materials by Acoustic Emission Method

The results show that the main difference between fatigue behaviour of SLM and standard material is not only in total fatigue life (the SLM material has significantly worse fatigue resistance), but mainly in the length of fatigue stages and in mechanism of crack development. As we expected, the fatigue resistance of SLM is strongly affected by amount of production defects.
