3D Printing of Reinforced Concrete Components: A Mechanical-Civil Interface Approach
Year: 2025
Type: article
Abstract: The integration of 3D printing technology into the construction sector represents a transformative leap in how infrastructure can be designed, fabricated, and assembled. This research focuses on the development and mechanical-civil interface analysis of 3D printed reinforced concrete components, addressing the challenges of material flow, reinforcement embedding, structural integrity, and automation. A custom-designed extrusion-based printing system was developed to produce complex concrete geometries embedded with continuous and discrete reinforcements. The mechanical behavior under axial, flexural, and cyclic loading was experimentally investigated and compared with conventionally cast specimens. Additionally, finite element simulations were performed to optimize layer bonding, stress distribution, and reinforcement layout. From a civil engineering perspective, the study evaluates the viability of printed components for real-world load-bearing applications and seismic conditions. The findings highlight that with proper reinforcement strategies and print path optimization, 3D printed concrete can meet structural performance criteria while significantly reducing formwork, labor, and material waste. This work demonstrates the potential of interdisciplinary synergy in advancing sustainable and automated construction techniques.
