INFLUENCE OF PRINT PARAMETERS AND NOZZLE PATHWAY ON MECHANICAL PROPERTIES OF PRODUCTS OBTAINED BY ADDITIVE TECHNOLOGIES

Tema ovog diplomskog rada su aditivne tehnologije i utjecaj različitih parametara prilikom izrade tehnologijom taložnog očvršćivanja. U prvom dijelu rada prikazana je podjela polimernih materijala i različiti načini izrade istih. Zatim se detaljnije opisuju različite vrste aditivnih tehnologija kako bi se jasnije shvatilo koji su parametri testirani u eksperimentalnom dijelu rada. Eksperimentalni dio opisuje postupak izrade ispitnog tijela taložnim očvršćivanjem s nekoliko različitih parametara te se na istim ispituju rastezna i savojna svojstva.The main topic of this graduate thesis is additive technologies and the influence of different print parameters during the process of fused deposition modeling on mechanical properties of the final product. First part of the thesis presents the classification of polymer materials and different methods of producing them. Later on different methods of additive manufacturing are explored in more detail in order to better understand the parameters that were tested in the experimental part of the thesis. The experimental part describes the process of making specimens by fused deposition modeling with several parameters being altered. Later all the specimens are tested for tensile strength and flexural stress
