20.500.12556/RUL-171621 Zasnova in izdelava naprave za pridobivanje 3D filamenta iz plastenk Design and manufacturing of a device for obtaining 3D filament from plastic bottles Diplomska naloga obravnava zasnovo in samo izdelavo naprave, ki odpadne plastenke spremeni v uporabni filament za 3D tiskalnik. V prvem delu naloge je predstavljena PET plastika kot surovec za pridobivanje filamenta. Sledi opis 3D tiska in možnosti uporabe 3D tiska v industriji. V diplomski nalogi so opisane komponente, ki so uporabljene v napravi, ki smo jo zasnovali. Razložene so vezave prej omenjenih komponent, ter kako so uporabljene komponente pritrjene na samo napravo. Opisan je postopek uporabe naprave in stvari, ki se jih izogibamo. Sledi iskanje optimalnih parametrov temperature in hitrosti navijanja, ter parametrov za tiskanje s pridelanim PET filamentom. Na koncu je na osnovi natisnjenega izdelka predstavljena ˇse primerjava pridelanega PET filamenta s kupljenim filamentom PLA. The thesis deals with the design and construction of a device that turns waste plastic bottles into usable filament for a 3D printer. The first part of the thesis presents PET plastic as a raw material for obtaining filament. This is followed by a description of 3D printing and the possibilities of using 3D printing in industries. The thesis describes the components used in the device we designed. The connections of the mentioned components are explained and how the used components are attached to the device itself. The process of using the device and things to be avoided are described. This is followed by the search for optimal temperature and winding speed parameters for the device and parameters for printing with the produced PET filament. At the end, there is a comparison of the produced PET filament with the purchased PLA filament, where the filaments are compared on the basis of the printed product.
