Abstract: Kyrychuk R.V., Demchyna B.G. (supervisor). Glass domes made with the use of 3D printing. Master’s thesis - Lviv Polytechnic National University, Lviv, 2024. Extended abstract. Modern architectural and construction technologies are undergoing significant changes due to the introduction of innovative production methods, one of which is 3D printing technology. The use of 3D printing to create complex architectural elements, such as glass domes, opens up new horizons in design and construction, allowing for structures with a high level of detail, individual design, and optimized strength characteristics. This master’s thesis is devoted to a detailed study of the process of manufacturing glass domes using 3D printing, analyzing their physical and mechanical properties, technological aspects, and potential for commercial use. Study object. Assessing the strength and deformability of domed glass models made using 3D printing is one of the main objectives of this study. We plan to investigate in detail how stable and what changes in structure occur in glass domes under the influence of various types of loads. This will include analyzing the changes in the shape and size of the domes under load, as well as studying their ability to withstand internal and external influences in order to determine the optimal structural parameters to achieve the highest level of strength and stability. Scope of research. The created glass models include two types of structures: a glass ring shell dome and a ribbed ring dome. These models were made using an advanced 3D printing method, which allowed to accurately reproduce the geometric and structural features of each configuration. The purpose of the study. The purpose of this study is to comprehensively investigate the methodology for manufacturing glass domes using 3D printing technology, as well as to analyze in detail their technical, aesthetic, and operational characteristics. Research results. The results of the research have shown that the use of 3D printing for the manufacture of glass domes allows achieving a high level of detail and complexity of shapes that cannot be realized using traditional methods. It has been found that photopolymer materials enriched with nanoparticles provide high transparency and strength of structures. Laboratory tests have confirmed that such domes are highly resistant to mechanical stress and weathering. The study showed that 3D printing is a promising method of manufacturing glass domes, which can significantly expand the possibilities of architectural design and construction. This technology ensures the creation of unique structures with high technical and aesthetic characteristics. The economic analysis showed that with the development of technology and an increase in production scale, a significant reduction in the cost of manufacturing glass domes is possible. Further research will be aimed at exploring the possibilities of combining different materials to increase the strength and durability of glass domes, as well as developing new 3D printing methods that will reduce the cost and production time.
