TO3DPGS – The Future Of Glass: Development of an Algorithm for Topology Optimized 3D Printed Glass Structures

This thesis investigates the use of topology optimization for large-scale glass structures in architecture, focusing on overcoming the limitations of traditional casting or float lamination methods by utilizing 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. The study addresses challenges such as the brittle nature of glass and the differences in tensile and compressive strengths.

Advancing the SIMP methodology (gradient-based), 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 (Dijkstra and medial axis offsets). 

Testing in a predefined design domain validates the solutions, resulting in a feasible design for 3D printing. 

Three physical glass models were produced using printing*, casting, and waterjet cutting!
