20.500.12556/RUL-172794 Reprodukcija taktilnih naravnih materialov za slepe in slabovidne s tehnologijo 3D-tiska Reproduction of tactile natural materials for the blind and visually impaired using 3D-printing Dostop do narave in botanike ostaja za slepe in slabovidne omejen. Z diplomsko nalogo smo zato želeli raziskati načine modeliranja, 3D-tiska in naknadne obdelave taktilnih reprodukcij rastlin za slepe in slabovidne. Pri reproduciranju smo se omejili na dve rastlinski vrsti, in sicer na srhkodlakavi oman in alpsko možino. V teoretičnem delu smo predstavili taktilno zaznavanje slepih in slabovidnih, tehnologijo 3D-tiska in načine za oblikovanje ter naknadno obdelavo 3D-tiskanih taktilnih reprodukcij. V eksperimentalnem delu smo reprodukcije socvetja srhkodlakavega omana oblikovali na dva načina – z digitalnim kiparjenjem in z generiranimi višinskimi mapami. Reprodukcijo socvetja in podpornih listov alpske možine smo oblikovali s kombinacijo obeh postopkov. Stebelne liste srhkodlakavega omana smo oblikovali s sivinsko sliko, ki smo jo ustvarili sami. Modeli so bili natisnjeni s PLA filamentom in glede na željene površinske lastnosti različno naknadno obdelani. Metode naknadne obdelave za doseganje gladkosti so obsegale vse od brušenja do lakiranja z mat sprejem in lakom z elastičnim učinkom. Mehkobo površine reprodukcije stebelnih listov srhkodlakavega omana smo poskušali doseči z brušenjem, žametnim prahom in pasto z učinkom mahu. Da bi bile reprodukcije prilagojene tudi za slabovidne, smo modele barvali z akrilnimi barvami, pod katere smo nanesli temelj za plastiko. Taktilne reprodukcije smo s 3D-tiskom in z naknadno obdelavo uspešno izdelali in dobili pozitiven odziv slepih in slabovidnih pri tipnem testiranju. Access to nature and botany remains limited for individuals who are blind or visually impaired. This diploma thesis aimed to explore methods of designing, 3D-printing, and post-processing tactile plant reproductions for the blind and visually impaired. The reproduction was limited to two plant species: Inula hirta and Eryngium alpinum. The theoretical part presents the tactile perception of blind and visually impaired individuals, 3D-printing technology and approaches to designing and post-processing 3D-printed tactile models. In the experimental part, we reproduced the inflorescence of Inula hirta using two methods – digital sculpting and AI-generated depth maps. The reproducted model of the inflorescence and bracts of Eryngium alpinum was created by using a combination of both approaches. The stem leaves of Inula hirta were modelled from a custom-made grayscale image. The models were printed with the use of a PLA filament and post-processed in different ways depending on the desired surface properties. Methods to achieve smoothness of the model included everything from sanding, matte spray coating, to the use of elastic-effect varnish. To create a soft surface for the stem leaves, we used sanding, velvet powder, and moss-effect paste. To ensure the models were suitable for the visually impaired as well, we painted them with acrylic colours and applied a plastic primer underneath. The tactile reproductions were successfully created using 3D-printing and post-processing, resulting in positive feedback from blind and visually impaired participants during tactile testing. 3D-tisk 3D-modeliranje digitalno kiparjenje taktilna reprodukcija slepi in slabovidni rastline 3D-printing 3D-modelling 3D-sculpting tactile reproduction blind and visually impaired plants true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-11 09:02:44 2025-09-11 09:02:46 2025-10-24 03:43:16 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 107509 26188.pdf 26188.pdf 1 2AF9A509CFBC7F2A0B2163C1A2571A90 4dbbb6079d2453695d8036199b387053f2ef2e8e670bce60fb7a25ea9f0309c1 2872912d-8edd-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=216843 Naravoslovnotehniška fakulteta 0 0 0
