Abstract
Aditivna proizvodnja je proces trodimenzionalog ispisivanja tijela prethodno dizajniranog u računalnom programu koji se temelji na nanošenju materijala sloj po sloj do konačnog proizvoda. Proizvodnja rastaljenim filamentom jedan je od postupaka aditivne proizvodnje koji se temelji na nanošenju zagrijanog materijala sloj po sloj. Ovim postupkom 3D-ispisane su epruvete od poli(vinil-butirala) i plastomernog poliuretana pod kutovima 0° i 45° u različitim debljinama sloja. U svrhu karakterizacije 3D-ispisanih dijelova izrađenih različitim debljinama slojeva i pod različitim kutovima provedeno je mehaničko ispitivanje statičkim vlačnim testom. Provedeno je ispitivanje kemijskih svojstava testom bubrenja kako bi se ispitala topljivost ovih materijala u različitim otapalima i FTIR analiza za potvrdu kemijskog sastava uzorka. Ispitivanje toplinskih svojstava istraženo je razlikovnom pretražnom kalorimetrijom. Rezultati ispitivanja svojstava pokazali su kako uzorci ispisani pod kutom od 0° imaju veću vlačnu čvrstoću od uzoraka ispisanih pod kutom od 45°. Testom bubrenja utvrđena su otapala u kojima materijali najviše bubre, a FTIR analizom potvrđene su karakteristične skupine za oba materijala. Razlikovnom pretražnom kalorimetrijom utvrđeno je da plastomerni poliuretan sadrži amorfnu i kristalnu fazu, dok poli(vinil-butiral) pokazuje amorfna svojstva.
Abstract (english)
Additive manufacturing is the process of three-dimensional printing of a body previously designed in a computer program. Fused filament fabrication is one of the processes of additive manufacturing, which is based on the application of heated material layer by layer to the desired model. Using this process, test tubes made of poly(vinyl-butyral) and thermoplastic polyurethane were printed at angles of 0° and 45° in different layer thicknesses. For the purpose of characterizing 3D-printed parts made with different layer thicknesses and at different angles, mechanical a static tensile tests were performed. Chemical properties were tested by swelling test to test the solubility of these materials in different solvents and FTIR analysis was perfomed to confirm the chemical composition of the sample. Thermal properties were tested by differential scanning calorimetry. The test results showed that samples printed at an angle of 0° have higher tensile strength than samples printed at an angle of 45°. The swelling test determined the solvents in which the materials swell the most, and the FTIR analysis confirmed the characteristic groups for both materials. Differential scanning calorimetry showed that thermoplastic polyurethane contains amorphous and crystalline phases, while poly(vinyl-butyral) shows amorphous properties.
