This study presents an experimental investigation to improve Selective Laser Melting (SLM) regarding
aspects such as surface roughness, density, precision and micro machining capability by employing
secondary processes such as Selective Laser Erosion (SLE) and laser re-melting. SLM is a layered additive
manufacturing technique for the direct fabrication of functional parts by fusing together metal powder
particles. Laser re-melting, applied after each layer or only on the top surfaces, is used to improve the
roughness and density while SLE, a subtractive process, is combined with SLM to improve the precision
and micro machining capability.
