Abstract

Raziskava obravnava vpliv različnih geometrijskih struktur na mehanske lastnosti komponent, izdelanih s postopkom aditivne proizvodnje, natančneje FDM 3D-tiskanja. Pri sodobnih pristopih k optimizaciji mehanskih lastnosti materialov, ki se uporabljajo v 3D-tiskanju, igra ključno vlogo notranja struktura oziroma geometrija izpolnilne strukture. V raziskavi so analizirane različne vrste notranjih struktur (heksagonalna, trikotna in linearna) ter njihova gostota. Posebna pozornost je namenjena vplivu teh parametrov na natezno trdnost natisnjenih komponent, kjer so bili izvedeni praktični preizkusi v laboratorijskem okolju. Rezultati kažejo, da izbira primerne geometrijske strukture pomembno vpliva na mehansko zmogljivost izdelkov in omogoča ciljno prilagajanje lastnosti glede na funkcionalne zahteve. Ugotovitve predstavljajo uporabno osnovo za načrtovanje tehnično in ekonomsko optimiziranih 3D-natisnjenih komponent še posebej na področjih, kjer sta nizka masa in visoka mehanska odpornost ključnega pomena.

Secondary title:	THE INFLUENCE OF DIFFERENT GEOMETRIC INFILL STRUCTURES ON THE MECHANICAL PROPERTIES OF 3D PRINTED COMPONENTS
Secondary abstract:	The research investigates the impact of various geometric structures on the mechanical properties of components produced using additive manufacturing, specifically FDM (Fused Deposition Modeling) 3D printing. In modern approaches to optimizing the mechanical properties of materials used in 3D printing, the internal structure or infill geometry plays a crucial role. The study analyzes different types of internal structures (hexagonal, triangular, and linear) and their densities. Special attention is given to the influence of these parameters on the tensile strength of printed components, with practical tests conducted in a laboratory setting. The results show that the choice of an appropriate geometric structure significantly affects the mechanical performance of the products and enables targeted adjustment of properties based on functional requirements. The findings provide a practical basis for designing technically and economically optimized 3D-printed components, particularly in fields where low weight and high mechanical resistance are essential.
