Abstract:Magistrsko delo obravnava vpliv debeline slojev, števila konturnih sten, gostote in oblike polnilne strukture ter izpostavljenosti hladilno-mazalnemu sredstvu na mehanske lastnosti materialov PLA in PLA+CF, izdelanih s tehnologijo FDM. Rezultati nateznih preizkusov kažejo, da manjša debelina sloja, večje število konturnih sten ter večja gostota in kompleksnejša oblika polnilne strukture izboljšajo mehanske lastnosti. Dolgotrajna izpostavljenost hladilno-mazalnemu sredstvu vodi v poslabšanje mehanskih lastnosti, pri čemer je učinek izrazitejši pri nižjih gostotah polnilne strukture.

Title:ANALYSIS OF THE INFLUENCE OF STRUCTURAL PARAMETERS AND ENVIRONMENTAL FACTORS ON THE MECHANICAL PROPERTIES OF FDM 3D-PRINTED PLA AND PLA-CF MATERIALS
Abstract:This master's thesis investigates the effect of layer thickness, contour wall number, infill density and pattern, and exposure to coolant-lubricant fluid on the mechanical properties of PLA and PLA+CF materials printed using FDM. Tests show that thinner layers, more walls, and denser infill improve strength, while long-term fluid exposure lowers performance, especially at low densities.
Keywords:Polylactic acid, Carbon fiber reinforced polylactic acid, 3D-FDM printing technology, Mechanical properties of materials, Infill density, Coolant-lubricant fluids, Infill pattern
