This thesis investigates the development of a topology optimization algorithm for large-scale glass structures in architecture made by 3D printed glass. Previous studies highlighted the lack of transparency in topology-optimized cast glass, prompting this research to explore the unique properties and manufacturing techniques of 3D printed glass instead. The study addresses challenges such as the brittle nature of glass and the difference in its tensile and compressive strength, with an additional focus on integrating in the algorithm the fabrication limitations linked to Additive Manufacturing of Glass as a production method.

A thorough literature review underpins the research, examining glass properties, manufacturing techniques, and topology optimization principles. The study advances the SIMP methodology, adapting it to 3D printed glass constraints like overhangs, path continuity, and nozzle size. Specific adjustments include layer-to-layer overhang filters and advanced computing techniques for path control.

The implementation details and testing within a predefined design domain validate the proposed solutions, leading to the selection of a feasible design for 3D printing. The results emphasize the need for further research, especially on the anisotropy of glass layers.

Two physical glass models were produced through casting and waterjet cutting.
