         "volume": "12876","abstract": "In powder bed fusion with laser beams (PBF-LB/M), the component's quality and mechanical properties are limited by \r\nrestricted process parameter combinations and the geometry of the component. Combining PBF-LB/M with ultrashort laser \r\nablation enables additional control of the heat flow to adjust local solidification. On the one hand it is possible to print \r\nheat-dissipating structures, which can be added and removed during the build process. On the other hand, ablated slits in \r\nthe component can serve as a thermal barrier.\r\nTo investigate the effect of slits and heat-dissipation structures on the local temperature field and solidification conditions, \r\na numerical model was developed. Two different ablation strategies were investigated and compared to conventional \r\nPBF-LB. Numerical investigations of an additively manufactured AlSi10Mg component showed a larger melt pool, a lower \r\ntemperature gradient, and a lower cooling rate if there are slits present next to the current PBF-LB track.\r\nThis approach provides the potential to independently adjust microstructure and mechanical properties, exceeding \r\nlimitations imposed by the component's geometry in conventional additive manufacturing.",
