Robotic 3D printing has the potential of revolutionising the concrete industry and contributes towards more sustainable concrete construction through material optimisation, carbon emission and waste reduction, design freedom and greater precision. This study aims to develop a prototype of bespoke infrastructure elements using Robotic 3D printing technology. Optimised mix design for low carbon 3D printed concrete with enhanced fresh and hardened properties will be proposed. The structural performance will be enhanced through incorporation of short fibres and embedding reinforcing bars. The outcomes will give positive impact to precast drainage, sewerage and civil infrastructure industries.
