STRESS-BASED DESIGN

For 3D concrete-printed horizontal structures

DLightBeam+ is the second iteration of the 3DLightBeam research project, which aims to combine computational design with the freedom of form provided by 3D Concrete Printing (3DCP) technology to challenge conventional reinforced concrete structures by exploring new design solutions for carbon-efficient concrete beams. 3DLightBeam+ enables structurally reliable, load-bearing printed beams with reduced carbon impact through multi-hierarchical stress-based design optimisation. 3DLightBeam+ is shape-optimised to maximise bending capacity while reducing weight. Its internal infill design is inspired by the structure of bones, enabling it to work in pure compression and tension. High-resolution material deposition is achieved through data-driven robot control, allowing concrete and steel reinforcement to be placed only where needed, avoiding material inefficiencies. The structure can be applied on existing construction sites and, at this stage, reduce concrete CO2 emissions by 19.3%.
