20.500.12556/DKUM-94085 Primerjava kakovosti profesionalnih in industrijskih fdm 3d tiskalnikov Comparison of the quality of professional and industrial fdm 3d printers V diplomskem delu je predstavljana primerjalna analiza treh FDM 3D-tiskalnikov, pri čemer sta bila v ospredju primerjava domačih naprav z industrijsko rešitvijo ter ocena njihove zmogljivosti pri izdelavi funkcionalnih komponent. V teoretičnem delu so podane osnove tehnologije FDM tiskanja, princip delovanja 3D optičnega skeniranja, računalniške tomografije in metode za merjenje deformacij. V eksperimentalnem delu so bili natisnjeni standardizirani natezni preizkušanci (ISO 527-2 tip 1A) v zahtevnejši vertikalni orientaciji. Natisnjeni vzorci so bili najprej analizirani z vidika geometrijskih odstopanj in poroznosti, nato pa natezno preizkušeni. Z optičnimi in volumetričnimi analizami je bila ocenjena natančnost izdelave, z nateznimi preizkusi pa mehanska zmogljivost v smeri slojev. Na koncu so bili rezultati statistično obdelani in medsebojno primerjani. Rezultati so pokazali pomembne razlike med napravami, tako glede dimenzijske natančnosti kot tudi mehanske trdnosti, ponovljivosti in notranje strukture. Delo omogoča boljše razumevanje prednosti in omejitev posameznih pristopov pri FDM tiskanju ter predstavlja podlago za premišljeno izbiro naprave glede na končne zahteve uporabe. This thesis presents a comparative analysis of three FDM 3D printers, focusing on the comparison between consumer-grade devices and an industrial solution, and evaluating their performance in the production of functional components. The theoretical section introduces the fundamentals of FDM printing, the principles of 3D optical scanning, computed tomography (CT), and deformation measurement techniques. In the experimental part, standardized tensile specimens (ISO 527-2 type 1A) were printed in a challenging vertical orientation. The printed samples were first analysed for geometric deviations and porosity, followed by tensile testing. Dimensional accuracy was assessed through optical and volumetric analyses, while mechanical performance in the Z-direction was evaluated with tensile testing. The results were then statistically processed and compared across the three devices. The findings revealed notable differences in dimensional precision, mechanical strength, repeatability, and internal structure. The study offers insight into the strengths and limitations of different FDM approaches and provides a foundation for informed printer selection based on end-use requirements. 3D-tiskanje FDM dimenzijska natančnost poroznost računalniška tomografija natezni preizkus mehanske lastnosti 3D printing FDM dimensional accuracy porosity computed tomography tensile testing mechanical properties true true false [M.
