Enhancing inter-layer bond in 3D concrete printing using topological design principle: Research on effect of topological interlocking in extrusion-based 3D printable concrete

Conventional construction techniques are unsustainable and expensive due to longer construction time, labour-intensive work, and the use of formwork. 3D concrete printing is seen as a potential substitute to overcome these issues. However, extrusion-based 3D printed structures exhibit a weak interlayer bond, and researchers have tried to address...
