| description | Abstract The advancement of construction 3D printing (C3DP) relies heavily on optimizing the material formulation and hardware configuration. This study reports the development of a customized extrusion system—comprising a hopper, auger, and interchangeable nozzles— designed for use with locally sourced, cost-effective cementitious composites. A series of composite mixes were evaluated, with the CSSAW mix (cement, fine sand, fine soil, admixture, and water) exhibiting superior printability, achieving a slump height of 27 cm after 30 min and maintaining structural integrity across 11 printed layers. Compared to the baseline CSW mix, CSSAW showed a 92.8% improvement in flowability and a threefold enhancement in shape retention. Optimization of printing parameters, including a speed of 25 mm/s and layer height of 10 mm, further improved interlayer adhesion and surface quality. The rectangular nozzle was found to enhance deposition consistency and print stability. The findings establish a practical framework for deploying C3DP in real-world construction setups using sustainable materials and scalable extrusion systems. |
