Abstract:Magistrsko delo obravnava upogibne lastnosti različnih polimernih in kompozitnih materialov, izdelanih s FDM 3D tiskanjem. Osrednji cilj raziskave je analiza vpliva gostote heksagonalne izpolnitvene strukture in izpostavljenosti hladilno-mazilnemu sredstvu (emulziji) na mehanske lastnosti materialov PLA, PLA+CF in PA+CF. V okviru eksperimentalnega dela so bili izvedeni tritočkovni upogibni testi na vzorcih, pri čemer so bile sistematično preučene razlike v odpornosti na obremenitve ter degradacija materialov. Rezultati kažejo, da večja gostota polnila izboljšuje upogibne mehanske lastnosti, medtem ko dolgotrajna izpostavljenost emulziji lahko zmanjša strukturno celovitost vzorcev. Kompozitni materiali PLA+CF in PA+CF so pokazali boljše mehanske lastnosti v primerjavi s čistim PLA, vendar se njihova odpornost na vplive emulzije razlikuje. Ugotovitve prispevajo k optimizaciji parametrov FDM 3D tiskanja in razumevanju vpliva okoljskih dejavnikov na delovanje polimernih kompozitov.

Title:CHARACTERISATION AND ANALYSIS OF THE FLEXURAL PROPERTIES OF 3D PRINTED POLYMER AND COMPOSITE MATERIALS
Abstract:This master's thesis investigates the flexural properties of various polymer and composite materials manufactured using Fused Deposition Modeling (FDM) 3D printing. The primary objective of the research is to analyze the impact of hexagonal infill density and prolonged exposure to a cooling lubricant (emulsion) on the mechanical properties of PLA, PLA+CF, and PA+CF materials. The experimental study involved three-point bending tests on printed specimens, systematically evaluating their resistance to mechanical loads and the effects of material degradation. The results indicate that higher infill densities enhance flexural mechanical properties, whereas extended exposure to emulsion can compromise the structural integrity of the samples. Composite materials PLA+CF and PA+CF demonstrated superior mechanical performance compared to pure PLA, although their susceptibility to emulsion exposure varied. The findings contribute to the optimization of FDM 3D printing parameters and provide deeper insights into the environmental influences affecting the performance of polymer composites.
