Powder bed fusion of metal with laser beam (PBF-LB/M) is an additive manufacturing process that uses a laser beam to melt dimensionless metal powder and then build it up layer by layer to form a three-dimensional component (Ref. 1). With this manufacturing process, it is possible to produce complex component geometries (Ref. 1) that are difficult to realize using conventional methods (e.g., casting technology and machining). Unfortunately, there are still restrictions that hinder its widespread usage in industry. E..
