Abstract

The increasing demand for sustainable construction materials has driven significant interest in eco-brick manufacturing using recycled waste and additive manufacturing technologies. However, prior studies often face challenges such as reduced mechanical strength, anisotropic behavior, weak interlayer bonding, and limited diversity in recycled material utilization. This paper presents a novel framework for fabricating sustainable 3D-printed eco-bricks from recycled waste materials including construction and demolition debris, recycled sand, glass powder, and plastic waste. By optimizing material composition, layer deposition parameters, and interfacial bonding strategies, the proposed method overcomes strength anisotropy and interface weaknesses commonly observed in layered printing. Experimental evaluations demonstrate enhanced compressive strength, durability, dimensional accuracy, and thermal insulation properties compared to conventional concrete bricks. Furthermore, life cycle analysis indicates a significant reduction in carbon footprint and resource consumption, contributing to circular economy objectives. The developed 3D-printed eco-brick system offers a scalable, energy-efficient, and environmentally responsible solution for modern green construction applications
