Fiber-Reinforced 3D Concrete Printing for Structural Applications
3D concrete printing
3D concrete printing is rapidly evolving from a laboratory-based technology into a viable construction method for real-world structural applications. To enable this transition, printed elements must exhibit sufficient robustness during manufacturing, transportation, and service life. However, concrete produced through extrusion-based printing has limited tensile strength and ductility. Therefore, effective reinforcement strategies are essential. Among the available options, the integration of fiber reinforcement is particularly promising, as it can enhance mechanical performance without compromising the geometric freedom that makes 3D concrete printing attractive in the first place.
In this MSc graduation project, conducted in collaboration with Weber Beamix, you will investigate the relationship between fiber reinforcement and the printability of cementitious materials. The research will focus on the trade-off between manufacturing performance (including mixing, pumping, extrusion, and process stability) and structural performance after hardening (such as strength, toughness, and durability).
The project combines experimental work with data analysis. You will design and perform laboratory experiments involving both conventional mechanical testing and advanced monitoring techniques using online and inline sensor systems. The collected data will be analysed to identify key parameters governing material behavior throughout the printing process and in the hardened state.
The outcomes of the project will contribute to the development of robust, fiber-reinforced 3D printing solutions for structural applications. In close collaboration with the industrial partner, the most promising findings may be translated into a practical application case, providing an opportunity to demonstrate the technology and its performance in a realistic setting.
