20.500.12556/RUL-188905 Optimizacija VPP (DLP) 3D-tiskanja z uporabo metode načrtovanja eksperimentov (DOE) Optimization of the VPP (DLP) 3D printing using the design of experiments (DOE) method Magistrsko delo obravnava optimizacijo procesa VPP (DLP) 3D-tiskanja z namenom izboljšanja dimenzijske natančnosti izdelanih vzorcev. Delo je obravnavalo konstrukcijsko nadgradnjo laboratorijskega 3D-tiskalnika z izdelavo po višini nastavljive platforme optičnega sistema in razvoj merilnega sistema za spremljanje temperature fotopolimera med procesom tiskanja. Za vrednotenje vpliva procesnih parametrov je bil zasnovan testni poligon z različnimi geometrijskimi značilkami. Optimizacija procesnih parametrov je temeljila na metodi načrtovanja eksperimentov (DOE), kjer je bila uporabljena ortogonalna matrika. Obravnavani so bili vplivi debeline sloja, časa osvetlitve posameznega sloja in temperature fotopolimera. Dimenzijske meritve izbranih geometrijskih značilk so bile izvedene z digitalnim optičnim mikroskopom, rezultati pa statistično obdelani z analizo aritmetičnih sredin, razmerja signal-šum (S/N) in analizo variance (ANOVA). Na podlagi izvedenih eksperimentov in statistične analize rezultatov je bil določen optimalni nabor procesnih parametrov za obravnavani sistem tiskanja VPP (DLP). This master's thesis addresses the optimization of the Vat Photopolymerization (VPP) process based on Digital Light Processing (DLP) technology with the aim of improving the dimensional accuracy of fabricated specimens. The research included a structural upgrade of a laboratory DLP 3D printer through the development of a height-adjustable platform for the optical system and the design of a measurement system for monitoring the temperature of the photopolymer during the printing process. To evaluate the influence of process parameters, a test specimen incorporating various geometric features was designed. The optimization of the process parameters was carried out using the Design of Experiments (DOE) methodology based on an orthogonal array. The effects of layer thickness, exposure time per layer, and photopolymer temperature were investigated. Dimensional measurements of the selected geometric features were performed using a digital optical microscope, while the obtained results were statistically analysed using analysis of arithmetic means, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA). Based on the conducted experiments and statistical analysis of the results, the optimal set of process parameters for the investigated VPP (DLP) printing system was determined. fotopolimerizacija v kadi (VPP) načrtovanje eksperimentov (DOE) aditivne tehnologije 3D tiskanje fotopolimeri ortogonalne matrike optimizacija procesnih parametrov vat photopolymerization (VPP) design of experiments (DOE) additive manufacturing 3D printing photopolymers orthogonal arrays process parameter optimization true false false [A.
