Medslojna ojačitev polimernih izdelkov natisnjenih z metodo ciljnega nalaganja

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.

• Title: Interlayer reinforcement of polymer products printed by fused filament fabrication

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.
