Vpliv sestave 3D natisnjenih kompozitnih gradiv na oblikovno in dimenzijsko stabilnost v spreminjajočih klimatskih pogojih : diplomsko delo = Influence of the composition of 3D printed composites on shape and dimensional stability under changing climatic conditions : B. Sc. thesisKokot, MatevžV okviru diplomske naloge smo proučevali osnovne mehanske lastnosti in dimenzijsko stabilnost 3D natisnjenih vzorcev iz štirih različnih materialov v spreminjajočih se klimatskih pogojih. Uporabili ... smo čisti PLA ter tri lesno-plastične kompozite z različnimi deleži lesa (do 40 %, 15 % in 25 %). Vzorce smo najprej navlaževali, nato pa smo jih sušili ter spremljali njihove dimenzijske spremembe. S pridobljenimi informacijami o izbranih materialih smo se lotili priprave in izdelave vzorcev iz dveh različnih materialov (PLA in lesno-plastični kompozit) v različnih debelinah plasti v sestavljenem vzorcu. Za lažjo predstavo, kako se bodo naši preizkušanci odzivali, smo izpeljali računalniške simulacije v programu SolidWorks ter izbrali optimalne kombinacije debelin plasti in materialov, ki naj bi v spreminjajočih se klimatskih pogojih dosegli največje spremembe oblike. Material PLA je bil v vseh primerih izbran za pasivno plast, za aktivno plast smo izbrali materiala s 15 % in 25 % deležem lesenega prahu. Pri tako natisnjenih elementih smo ugotavljali njihov odziv na izpostavitev v vlažni klimi (RZV 88 %). S kombinacijo dveh materialov v enem elementu in z izpostavitvijo teh elementov v vlažni klimi smo sprožili avtonomen odziv sistemov (vzorci so se samodejno odklonili). Najbolj so spremenili obliko % se odklonili vzorci, ki so imeli v aktivni plasti material z večjim deležem lesa, na velikost in hitrost odklona pa vpliva tudi razmerje med debelino plasti PLA in lesno-plastičnega kompozita.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
