Design and Construction with 3D Concrete Printing (2025-12)¶

Digital processes, such as thin-walled concrete 3D printing, have enabled the production of geometrically complex concrete components for some time now. Through the formwork-free production of load- and material-optimised components, the technology can play a decisive role in the development and manufacture of efficient concrete components. However, there is no standardised procedure for dealing with material properties and structural design. Research on printing geometry and construction, as well as reinforcement technology, should lay the groundwork for initial steps towards structural design, ultimately ensuring the production of optimised components. Based on the design of prototype projects, the basic research on construction details and structural mechanics is carried out up to the stage of realisation. The theoretical work is always accompanied by experimental validation. A significant amount of concrete and reinforcing steel can be saved in reinforced concrete ceilings by using innovative, thin-walled formwork elements. Reinforcement and prestressing technology, along with innovations in printing technology, enable the production of filigree façade panels. The research results clearly show, based on practical construction applications, that concrete 3D printing can contribute to reducing material consumption and the environmental impact of components in an economical way.
