In this work, the influence of processing condition on relative density and mechanical properties of specimens prepared by Selective Laser Melting (SLM) technique using 18-Ni maraging steel powder was investigated. The results show that it is necessary to control laser energy density of about 65-80 J/mm^3 to obtain SLM specimens with relative density higher than 99.9%. In addition, it was confirmed that mechanical properties of dense SLM specimens were less influenced by building direction on the base plate.
