The thesis focused on the field of 3D modeling and 3D printing of ball-jointed dolls. In the theoretical part, we explored the history of ball-jointed dolls (shortened BJD) and their characteristics. We presented 3D modeling techniques, 3D printing technologies, and how these two areas were connected to doll design. In the experimental part, we described the process of designing and sketching a BJD doll using the Paint Tool SAI software with the help of a graphics tablet. We explained the process and techniques of 3D modeling a BJD doll using the 3D modeling software Blender. During the modeling process, we delved into various joints and the range of movement that the doll achieved. We familiarized ourselves with important file preparation features for 3D printing in the PreForm software and the 3D printer Form 2 made by FormLabs. The Form 2 printer operated on the technology of stereolithography (shortened SLA), which hardened photopolymer resin with laser ultraviolet (UV) light. We described the post-processing of the doll, printed in white photopolymer resin, which involved rinsing it in isopropyl alcohol (IPA) and further curing it with UV light. The process of stringing parts of the BJD doll and creating a wooden stand was also described. Finally, we delved into the range of movement achieved by the doll, described the process of photographing the final product, commented on the achievement of set goals and potential improvements, and evaluated the results.
