Abstract Selective Laser Melting (SLM) is a powder-based additive manufacturing capable to produce parts layer-by-layer from a 3D CAD model. Currently there is a growing interest in industry for applying this technology for generating objects with high geometrical complexity. To introduce SLM process into industry for manufacturing real components, high mechanical properties of final product must be achieved. Properties of the manufactured parts depend strongly on each single laser-melted track and each single layer, as well as the strength of the connections between them. In this study, effects of the processing parameters such as hatch distance on surface morphology are analyzed.

Deformation and failure behaviour of Ti-6Al-4V lattice structures manufactured by selective laser melting (SLM) (2015, background): “Selective laser melting (SLM) is an additive manufacturing process in which part geometry is progressively built up by selectively melting subsequent layers of metal powder, using a scanning laser beam under an inert gas atmosphere [34].”
Analysis of laser–melt pool–powder bed interaction during the selective laser melting of a stainless steel (2017, neutral): “One of the possible reasons for this is the occurrence of denudation zones near the melt-pool, already mentioned by Yadroitsev and Smurov et al. , 5 but never investigated extensively so far except in a recent work by Matthews.”
