During the metal-based additive manufacturing process “laser-based powder bed fusion” (short: PBF-LB/M) interruptions can occur throughout the build job. These interruptions may be planned to produce hybrid parts, e.g., to insert components or electronics into the part or to adapt the manufacturing process itself. But interruptions can also be fault-induced, which can occur due to system failures, insufficient available powder quantities or poor component and process characteristics. Depending on duration, temperature and ambient atmosphere, these interruptions can have major influences on the component’s properties. The effects of a process interruption on the microstructure and the tensile properties for the material AlSi10Mg are to be presented within this work. In addition the impact of process interruptions on the mechanical properties of the tested components is shown.
