Concurrent Topology and Orientation Optimisation of 3D-Printed Concrete Under Drucker–Prager Strength Constraints: Numerical and Experimental Validation

The layer-wise deposition process of three-dimensional concrete printing (3DPC) induces anisotropic behaviour, while cementitious materials exhibit pronounced tension–compression strength asymmetry. This study develops a concurrent topology and printing-direction optimisation framework for plain 3DPC under Drucker–Prag...
