Such initial surface roughness is known as a major drawback for adopting both SEBM and DMLS/SLM parts in the as-printed condition. This roughness is predominantly resulted from balling and dross formation during solidification in the melt pool [5], as well as the attachment of partially melted powder particles to the surface of the sintered part [6, 7].
