a Porosity map and b1–b12 morphology of the SLS processed powder bed using different laser power and scan speed. The dash-dotted line in a is the isoline of 19% porosity, i.e., the initial porosity is reduced by half. Left inset: schematics of the presenting segment, the HM range (dashed line) as well as the beam spot (dash-dotted line), and the distribution of the volumetric energy deposition
