Abstract

Pri aditivni tehnologiji ciljnega nalaganja (FFF) so izdelki anizotropni. Ta magistrska naloga se osredotoča na izboljšanje medslojne trdnosti 3D-tiskanih izdelkov, zlasti v smeri Z-osi tiskanja, kar zmanjšuje anizotropijo. Raziskava se osredotoča na oblikovanje, izdelavo in testiranje različnih 3D-natisnjenih vzorcev s kompozitnimi strukturami narejenimi med sloji. Vzorci ojačani z ogljikovimi vlakni so dosegali do 382 % večjo natezno trdnost v smeri pravokotno na smer tiskanja kot vzorci, narejeni izključno iz polilaktične kisline (PLA). Rezultati meritev so potrdili skladnost s teoretično izračunanimi vrednostmi.

Secondary title:	Interlayer reinforcement of polymer products printed by fused filament fabrication
Secondary abstract:	In additive manufacturing technology, particularly Fused Filament Fabrication (FFF), the products exhibit anisotropic characteristics. This master's thesis focuses on enhancing the interlayer strength of 3D-printed objects, especially in the direction of the Z-axis of printing, which reduces anisotropy. The research emphasizes the design, fabrication, and testing of various 3D-printed samples with composite structures created between layers. Samples reinforced with carbon fibers achieved up to 382 % greater tensile strength perpendicular to the printing direction compared to samples made solely from Polylactic acid (PLA). The measurement results have confirmed their consistency with the theoretically calculated values.
