As single laser powder bed fusion (PBF-L) gains acceptance and is implemented across industry, equipment manufacturers have introduced multi laser PBF-L machines to increase the scale and efficiency of the PBF-L process. The authors will present on the effect multi laser “stitching” has on the resultant microstructure and defects. Understanding these effects are especially important for the large part manufactures who will require stitching of their components by the multiple lasers. A multitude of optical and electron imaging techniques were employed alongside static and fatigue testing to perform the characterization. In addition to the investigation of the as built stitched microstructure, the effect of industry relevant heat treatments will be shared, including stress relief, hot isostatic pressing and solution heat treatments.
