20.500.12556/DKUM-89293 Obnašanje toge avksetične strukture izdelane iz PLA filamenta znotraj TPMS celice iz elastičnega TPU filamenta magistrsko delo Behavior of rigid auxetic structure made from PLA filament inside of TPMS cell made from elastic TPU filament Magistrsko delo je eksperimentalne narave. Modelirali smo TPMS celico gyroida in znotraj celice oblikovali avksetično geometrijo. Geometrija je izdelana iz bolj togega PLA filamenta, ostanek celice pa iz elastičnega TPU filamenta. Nato je bil izveden 3D-tisk več vzorcev, vključno z vzorci z majhnimi variacijami, kar je omogočilo primerjavo vpliva različnih sprememb geometrije. Mehansko testiranje je izvedeno tako, da so bili vzorci stisnjeni med dvema ploščama, pri čemer smo beležili sile stiskanja in istočasno snemali za nadaljnjo analizo z DIC programom. Pri analizi rezultatov smo primerjali SEA, CFE in Poissonovo število. The master’s thesis is conducted in an experimental nature, with a focus on auxetic behaviour. We modelled the TPMS cell of the gyroid and formed an auxetic geometry within it. The auxetic geometry is made of rigid PLA filament, while the rest of the cell is made of elastic TPU filament. Subsequently, we 3D-printed multiple samples, including those with minor variations, to compare the effects of different changes. Mechanical testing was performed by compressing the samples between two plates, while simultaneously recording compression forces and video footage for further analysis with DIC software. For the analysis, we will compare SEA, CFE and Poisson’s ratio. avksetična struktura 3D-tiskanje PLA filament TPU filament TPMS celica gyroid SEA CFE Poissonovo število Auxetic structure 3D print PLA filament TPU filament TPMS cell gyroid SEA CFE Poisson's ratio true true false [D.
