ABSTRACT
The paper presents the results of research on the surface geometric structure (SGS) of objects made of H13 tool steel reinforced with titanium carbide (TiC) nanoparticles with a concentration between 2.5 and 15 % vol., manufactured using the additive manufacturing method (AM) - selective laser melting (SLM). The variable parameters were the percentage of the reinforcing phase and the spatial orientation of the analysed surfaces, while the SLM process parameters were constant. The altitudinal and spatial SGS parameters obtained for the studied samples and surfaces are summarised and compared. The results showed a strong influence of the reinforcing phase content on the values of the surface roughness parameters - with the significant deterioration noted for samples with min. 10% TiC vol. The resulting surface quality was better for upward-facing than downward-facing produced at the same angle.
