Modeliranje, priprava in 3D tisk igralnega lika

Reberšek-Gavrič, Žan (author), Muck, Deja (mentor)

Namen diplomskega dela je bil modelirati, pripraviti model za tisk ter na koncu 3D natisniti igralni lik oziroma karakter za video igro z dvema različnima tehnikama tiska in jih primerjati. Začeli smo z risanjem koncepta, pri čemer smo za inspiracijo izhajali iz japonskega stila animejev in video igre Overwatch. Ko smo skico dokončali, smo uporabili odprtokodni program Blender, v katerem smo z različnimi operacijami zmodelirali dele našega lika, jih ustrezno združili v celoto, model pregledali in ga na koncu izvozili v datoteko .stl. V programih tiskalnikov, ki so namenjeni pretvorbi datoteke .stl modela v kodo G (Simplify3D in PreForm), smo še enkrat pregledali celoten karakter, ga ustrezno popravili, mu določili podporne strukture in uporabili primerne nastavitve. Prvi model smo natisnili na Wanhao Duplicator i3 Plus, ki deluje na osnovi tehnologij ekstrudiranja materiala oziroma termoplastov. Drugi model pa smo natisnili z uporabo tiskalnika Form 2, ki deluje na tehnologiji stereolitografije. Po končanem tisku smo igralnima likoma odstranili podporne strukture in ju analizirali. Izvedli smo časovno primerjavo tiska, analizirali kakovost izdelanih detajlov in površine ter izvedli celotno primerjavo. Analizirali smo tudi nekatere težave, do katerih je prišlo pri tisku. V sklopu diplomskega dela in njegovih raziskav smo prišli do ugotovitve, da je za tisk modelov z veliko detajli bolj primerna stereolitografija, ki je tudi dražja, kot tehnologija ekstrudiranja termoplastov, ki je cenejša in bolj primerna za enostavnejše modele.

• Title: Modeling, preparation and 3D printing of a video game character

Abstract

The aim of the diploma thesis was to model, prepare and 3D print a video game character with two different technologies, and compare them. We started by drawing the concept, while taking Japanese anime and the video game Overwatch for inspiration. After we finalized the sketch, we used the open source program Blender to model parts of our character using different techniques, joined them into one mesh, examined the model and exported it to the .stl format. We used printing software designed specifically for transforming the .stl files to G-code (Simplify3D and PreForm), to analyse the entire character again, correct it accordingly, add support structures and apply the appropriate settings. The first model was printed on the Wanhao Duplicator i3 Plus printer, which uses technology based on material extrusion. The second model was printed using the Form 2, a printer that works with stereolithography. When the printing was finished, we removed the support structures from the video game characters and analyzed them. We conducted a time comparison of printing, analyzed the quality of the details and surface, and made a complete comparison. We also analyzed some of the problems encountered in the press. As part of the thesis and its research, we came to the conclusion that stereolithography is more suitable for printing models with a lot of details and is also more expensive, while extrusion technology is cheaper and more suitable for simple models.
