Design and fabrication of a demonstration model for promoting low-carbon energy technologiesPezdevšek, Marko (Avtor) Kosinac, Garsija (Avtor) Pišotek, Boštjan (Avtor) Predin, Andrej (Avtor) Roger, Andraž (Avtor) Fike, Matej (Avtor) Hren, Gorazd (Avtor) modelnuclear power planthydro power plant3D printingCADThis article presents the design, construction and educational application of a large-scale model representing renewable energy facilities that do not yet exist. The model features a circular layout with a diameter of 2 metres, divided into two halves: the Mokrice Hydropower Plant and a nuclear power plant with an accompanying low- and intermediate-level radioactive waste repository. The Mokrice half highlights key ecological and technical features, including two fish passages and a solar power plant installation, with realistic water effects achieved using epoxy resin. The nuclear half includes a removable low- and intermediate-level radioactive waste repository, allowing viewers to explore the storage arrangements via a cross-sectional view. All the components were fabricated using FDM 3D printing, assembled, finished with paint and landscaping materials, and mounted on a wooden base with a metal support structure. While the model was not intended to achieve exact technical scaling, it communicates complex energy infrastructures effectively, facilitating public understanding, awareness and dialogue about low-carbon technologies. The combination of additive manufacturing, interactive features and detailed landscape representation, demonstrates the value of models as tools for education, demonstration, and the promotion of sustainable energy solutions.20252026-01-20 09:34:26Neznano96584UDK: 620.92/.98COBISS_ID: 265023235DOI: 10.18690/jet.18.3.169-176.2025ISSN pri članku: 1855-5748sl
