20.500.12556/RUL-109774 Vpliv hitrosti podajanja nitke na natančnost izdelave z metodo ciljnega nalaganja Influence of filament feeding speed on FDM manufacturing precision 3D-tisk je pogosto uporabljen za domačo uporabo, kjer je težko zagotavljati ves čas iste pogoje, zato je razumevanje zunanjih vplivov v povezavi s procesnimi parametri ključen del kvalitetnega izdelka. Predstavljen je vpliv hitrosti podajanja filamenta na kvaliteto izdelka pri metodi ciljnega nalaganja. Obravnavani so vzorci, natisnjeni pri različni hitrosti podajanja filamenta in enakih ostalih parametrih ter zunanjih vplivih. Obravnavali smo vpliv hitrosti podajanja na dimenzije in ugotovili da je potrebno ob novem filamentu vedno prvo kalibrirati proces. Z višanjem ali nižanjem hitrosti podajanja se debelina sten sorazmerno povečuje oziroma zmanjšuje. Zunanje dimenzije so večje kot debeline sten, zato je vpliv manjši, vendar vseeno prisoten. 3D printing is often used for home use, where it is difficult to ensure the same conditions at all times. That is why understanding external influences in relation to process parameters is crucial for making a quality product. Presented in this thesis is the effect of filament flow rate on the quality of the product using fused deposition modeling. We researched the samples, printed at various filament flow rates while other paramaters and external influences are constant. We also researched the influence of various flow rates on the dimensions of the samples and found that it is necessary to calibrate the process before the new filament. By increasing or decreasing the flow rate, the thickness of the walls increases and decreases proportionally. The outside dimensions are larger than the thickness of the walls, so the impact is smaller, but still present. 3D tisk FDM metoda ciljnega nalaganja PLA polimlečna kislina hitrost podajanja filamenta natančnost izdelave kalibracija 3D tiskanja 3D print FDM fused deposition modeling PLA polyactic acid flow-rate manufacturing precision 3D print calibration true false false [A.
