Project description

Within this project we will further develop and prototype our patented, novel twin-pipe technology for fast 3D printing of concrete. A prototype device for the stiffening control of 3D printable concrete will be built, providing (1) a new type of static mixer specifically designed for fresh concrete 3D printing (high yield stress, high viscosity, and the presence of aggregates); and (2) a fully automated twin-pipe extrusion of blended fresh concrete. Altogether, the results will be used to further strengthen the technology readiness of the twin-pipe technology. This will provide a solid base for communication with commercial players interested in licensing and will create potential to start a spin-off and to establish the best licensing strategy.
