V diplomski nalogi je podrobno opisan postopek izdelave lutke z menjajočimi se obrazi za uporabo pri stop-motion animaciji. Glavni fokus naloge je: izdelava in animacija 3D-modela v računalniškem programu; izvoz, tisk in naknadna obdelava modelov; barvanje modelov ter izdelava funkcionalne lutke. 3D-tisk je hitro razvijajoča se panoga tehnologij, ki so v porastu posebej v zadnjih letih. Na voljo imamo različne tehnologije, ki nam ponujajo številne možnosti tiska, vsaka od njih pa ima svoje prednosti in slabosti. Cilji naloge so izdelava funkcionalnega 3D-modela lutke s pomočjo referenčnih slik, animacija 3D-modela in izvoz modelov za tisk, priprava modelov za tisk, tisk modelov in naknadna obdelava ter barvanje modelov in izdelava funkcionalne lutke za stop-motion animacijo. Najprej je bil izdelan načrt luke, po katerem smo v programu Blender s pomočjo referenčnih slik izdelali 3D-model človeške glave. Tako izdelan model smo nato razrezali na več delov, da smo dobili lutko z gibljivo glavo in menjajočimi se obrazi. Ko je bil model lutke končan smo animirali obraz s pomočjo ključev za preoblikovanje (ang. shape key). Izdelali smo ključno sličico za nasmeh, ter izdelali animacijo obraza iz resnega v nasmejanega, s 16-imi sličicami. Model obraza iz vsake posamezne sličice smo izvozili kot .stl datoteko. Poleg tega smo izvozili tudi modela glave ter ramen. Izvožene datoteke smo odprli v programu PreForm, ter jih v njem pripravili za tisk na SLA tiskalniku Form 2. Po tisku je sledila naknadna obdelava modelov. Modele smo najprej za 20 min potopili v kopel iz 90% raztopine izopropilnega alkohola, nato pa še odstranili podporne strukture. Na koncu smo natisnjene modele še pobarvali ter nanje nalepili magnete. Pri izdelavi 3D-modelov, ki jih nameravamo animirati je zelo pomembna topologija, saj ta vpliva na premikanje točk v mreži. Če je topologija neustrezna lahko pri animaciji modela pride do čudnih deformacij. Pri 3D-tisku, ki uporablja podporne strukture je potrebno le-te pravilno generirati. Prevelika gostota podpor oteži njihovo odstranjevanje, lahko pa tudi spremeni površino modelov. Po drugi strani pa premajhna gostota podpornih struktur povzroči, da se modeli sploh ne natisnejo. Odstranjevanje podpor s kleščami je pri modelih s tankimi stenami skoraj nemogoče, saj model poškodujemo. Tako smo prišli do zaključka, da je boljša metoda odstranjevanja podpor z vročim olfa nožem, saj modela ne poškoduje.

Naslov:3D-print in stop-motion animation
Izvleček:
The diploma thesis describes the process of making a puppet with replacement heads for use in stop-motion animation. The main focus of the diploma thesis was: creating and animating a 3D-model in a computer program; exporting, printing and post-processing of the models; and finally dyeing of models and making a functional puppet. 3D printing is a rapidly developing technology, which has been on the rise in recent years. We can choose between a variety of technologies that offer a wide range of printing options, each of which has its advantages and disadvantages. The goal of this project was to produce a functional 3Dmodel of the puppet, using reference images, animation of the 3D-model and export of models, preparation of models for print, model printing and post-processing, and in the end, the coloring of models and production of a functional puppet for stop-motion animation. First, a blueprint for the puppet was made, by which, a 3D-model of the human head was created in Blender program, using reference images. The model thus made was cut into several parts so we got a puppet with a moving head and a changing face. When the model of the puppet was finished, we animated the face with the shape keys. We created a keyframe for a smile, and made an animation from a serious to a smiling face with 16 different frames. The model of the face from each individual frame was exported as .stl file. In addition, we also exported head and shoulder models. The exported files were opened in the PreForm program and prepared for printing on the SLA Form 2 printer. The print was followed by post-processing of the models. The models were first immersed for 20 minutes in a bath of 90% solution of isopropyl alcohol, and then the removal of the support structures followed. In the end, the printed models were painted and glued with magnets. When creating 3D-models that we intend to animate, a very important thing to consider is the topology since it affects the movement of the mesh points. If the topology is inadequate, the model animation can cause strange deformations of the mesh. In 3D printing, which uses support structures, these must be properly generated. The excessive density of supports makes it difficult to remove them, and can also change the surface of the model. On the other hand, the unsufficient density of support structures can cause models not to print at all. Removing the supports with the pliers is almost impossible for thin-walled models, since the model can be damaged. In the end we came to the conclusion that the method with a hot utility knife is a better method of separation because it does not damage the model.
