20.500.12556/ReVIS-11637 Izdelava prototipov polimernih in kompozitnih konstrukcijskih elementov z uporabo sodobnih 3D tehnologij in FDM tehnologije aditivne proizvodnje Production of prototypes of polymeric and composite structural elements using modern 3d technologies and fdm technology of additive manufacturing Konstrukcijski elementi so ključni za prenos moči in gibanja v strojništvu, pri čemer se pogosto izdelujejo iz kovin z zahtevnimi in dragimi postopki. Aditivna proizvodna s tehnologijo nanašanja staljenega materiala omogoča izdelavo kompleksnih polimernih in kompozitnih oblik, vendar ostajajo odprta vprašanja glede njihovih mehanskih lastnosti in vzdržljivosti. Ta naloga preučuje možnosti in omejitve izdelave polimernih in kompozitnih zobnikov s to tehnologijo. Cilj je bil razviti CAD model, natisniti prototipe in oceniti njihove mehanske lastnosti. Študija analizira trdnost, odpornost proti obrabi, prenos navora in deformacijo pod obremenitvijo. Eksperimentalni testi s posebej zasnovano preizkusno napravo omogočajo merjenje navora in obrabe. Rezultati prispevajo k optimizaciji izdelave polimernih zobnikov za zanesljivo industrijsko uporabo. Structural components are fundamental to power transmission and motion in mechanical engineering, traditionally manufactured from metals using complex and costly processes. Additive manufacturing, particularly the fused deposition modelling (FDM) technique, enables the fabrication of intricate polymeric and composite structures; however, concerns regarding their mechanical properties and long-term durability persist. This study investigates the feasibility and limitations of producing polymer and composite gears using this technology. The objective was to develop a CAD model, fabricate prototypes, and evaluate their mechanical performance. The research encompasses and analysis of strength, wear resistance, torque transmission efficiency, and deformation under load. Experimental testing, conducted using a custom-designed test rig, facilitates precise torque measurement and wear analysis. The findings contribute to the optimization of polymer gear manufacturing, enhancing their reliability for industrial applications. 3d tiskanje aditivna proizvodnja fdm tehnologija kompozitni materiali konstrukcijski elementi polimerni materiali zobniki 3d printing additive manufacturing composite materials fdm technology gears polymeric materials structural elements true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-04-25 13:44:29 2025-04-25 13:44:29 2025-05-06 12:55:31 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 5366 233237507 DIP_Ropic_Matic_2025.pdf DIP_Ropic_Matic_2025.pdf 1 D794BA0FC64FB5C98C12825351AD19D2 ccba0cc1ae7bcd7de47ec700572ad4ca5c684ccddb6722ef9892b56d65d2e87e a5bcd38a-21ca-11f0-963a-001a4af901a5 https://revis.openscience.si/Dokument.php?lang=slv&id=13420 Univerza v Novem mestu - Fakulteta za strojništvo 0 0 0
