Coral reefs are under severe threat, with projections indicating a potential 90% decline by 2050 due to human-induced factors like pollution and global warming. Researchers are actively pursuing strategies for prevention, rehabilitation, and restoration. This thesis delves into the uncharted territory of paste-based printing, specifically Liquid Deposition Modeling (LDM) using clay. Despite clay's natural attributes like porosity and sustainability, its utilization for intricate shapes in 3D printing faces challenges, particularly in dealing with rough overhang angles, viscosity issues, and extended drying times. My research tackles these hurdles head-on, presenting and testing four innovative approaches to enhance clay's 3D printing capabilities for rough overhang angles, intervening in different stages of the traditional 3D-printing process or utilizing completely innovative techniques. The focus on overcoming challenges in printing overhanging elements positions this work at the forefront of advancing clay-based 3D printing for artificial reef creation. The findings not only enrich our understanding of clay's potential but also pave the way for more intricate designs in coral reef rehabilitation and restoration efforts.
