This diploma thesis examined the development of a three-dimensional printed puzzle based on three-dimensional modelling and a selected motif of Slovenian cultural heritage. Avgust Černigoj’s portrait of Srečko Kosovel was used as the visual source because of its clear constructivist structure and suitability for conversion from a two-dimensional image into a three-dimensional model. The purpose of the work was to develop and evaluate a prototype in which assembly would not rely only on conventional visual or edge-based puzzle logic, but also on spatial information created by height transitions between individual pieces.
The experimental work followed a design process with gradual phases. Initial relief puzzles without a motif were created to isolate the role of height transitions in assembly. The selected motif was then digitally prepared, manually reconstructed in Blender, converted into a three-dimensional form, adapted to a relief surface and divided into square pieces. The final model and frame were prepared for three-dimensional printing in Orca Slicer and printed using material extrusion technology with a thermoplastic polylactic acid filament.
The developed prototypes confirmed that height transitions can support the assembly of a three-dimensional puzzle, although their effectiveness depends on the clarity of the relief structure and on additional orientation cues such as surface texture and motif readability. The final prototype preserved the main visual characteristics of the selected portrait while also establishing a tactile and spatial form of interaction.
The work demonstrated that a three-dimensional puzzle can function as a distinct approach to assembling, interpreting and experiencing visual content. Its potential was identified in education, museum and gallery interpretation, accessibility for blind and visually impaired users, play and further design research.
