The construction industry is facing serious problems, mainly resulting from low productivity and an increasing shortage of skilled workers. The targeted digitalisation and automation of all relevant processes - from planning and dimensioning to the actual construction process - seem to be the only viable solution to overcome the urgent challenges. In this context, concrete 3D printing mainly focuses on the production of unreinforced component structures, while the proposed solutions for the integration of reinforcement are still rudimentary.
The current state of research of CONPrint3D® allows solid wall printing of unreinforced concrete components under laboratory conditions at a scale of 1:1. In the next development step, the application scenarios are to be expanded to include more highly stressed components.
This requires reinforcement integration in CONPrint3D®-printed components. Since steel is by far the most commonly used reinforcement material in concrete construction both in Germany and worldwide, the proposed project focuses on this type of reinforcement, i.e. on the production of reinforced concrete walls through additive manufacturing. This ensures that the project results can be transferred relatively quickly into construction practice within the framework of the existing standardisation of concrete structures.
