| Abstract Scope |
Recent advances in additive manufacturing have created new opportunities for concrete constructions, improving design freedom, accelerating fabrication, and reducing reliance on conventional formwork. However, the reliability of 3D-printed cementitious components remains limited by process- induced uncertainties, particularly those associated with layer-wise deformation, interlayer bonding, and material heterogeneity during deposition. These challenges are strongly governed by key printing parameters and continue to hinder large-scale implementations. This study investigates a 3D-printed smart beam concept designed to self-sense structural conditions during fabrication. The sensing functionality is achieved through the incorporation of functionalized layers fabricated by incorporating graphite powder and carbon microfibers within the cementitious mix that boosts the material’s piezoresistive behavior. This work studies how the smart beam’s signal can be leveraged to conduct quality control and quality assessment during the print. Results demonstrate that the electrical signal can be combined with a digital twin to track the layering process. |
