Summary of A 01

This project focusses on high-resolution particle-bed 3D printing of reinforced cementitious composites as a novel technology in the construction industry. To pioneer the understanding of governing mechanisms affecting the material-process interaction, basic interdisciplinary research addressing particle surface functionalisation, tailoring of particle size distribution, particle-bed compaction, liquid intrusion, interparticle and interlayer bonding, active structural build-up control of the matrix, high precision geometries as well as reinforcement integration will be conducted.
