Re-melting strategies with same and opposite directions to the first scanning routine were performed in AlSi10Mg parts by selective laser melting (SLM) technology. Surface roughness and porosity were investigated with confocal microscopy, micro-computed tomography (CT) and optical microscopy (OM). R...
