Abstract: This work aimed at optimizing the robustness and controllability of the production of porous Ti6Al4V structures using selective laser melting (SLM) by reducing the mismatch between designed and as-produced morphological and mechanical properties in two runs. In the first run, porous Ti6Al4V structures with different pore sizes were designed, manufactured by SLM, analyzed by microfocus X-ray computed tomography (micro-CT) image analysis and compared to the original design. The comparison was based on the following morphological parameters: pore size, strut thickness, porosity, surface area and structure volume. Based on correlations between designed and measured properties, their mismatch was in the second run decreased significantly from 45% to 5% for pore size. The demonstrated protocol is furthermore applicable to other 3D structures, properties and production techniques
