This article is focused on the effect of position on a build platform on the hardness, roughness and corrosion rate of parts (Ti6Al4V) produced by direct metal laser sintering (DMLS) technology. During the sintering process, the test samples were located at key positions—at the corners and in the middle of the build platform. An experimental program started with a microstructure investigation in two perpendicular directions in individual positions. The selected mechanical property—hardness—was investigated on metallographic cuts in both directions and all positions, and data sets underwent a statistical analysis (analysis of variance (ANOVA), t-test, F-test). The same procedure was repeated for an assessment of position effect to surface roughness (Kruskal–Wallis test) and material corrosion resistance. On the build platform, the course of hardness, roughness, and corrosion rate values that can be expected in individual positions was mapped in detail.
