Digital manufacturing methods and, in particular, the additive manufacturing of formwork elements expand the geometric repertoire of precast concrete members and thus form the basis for the production of highly differentiated and load-adapted concrete components. In order to be able to use the full potential of digital manufacturing methods in modular precast concrete construction, computer-based methods are necessary for the design and planning of the corresponding components and structures. By feeding back production-specific parameters, these methods are able to inform the early design process in a targeted manner and thus ensure efficient and material-appropriate planning of specific components and enable dividing the entire structure into appropriate individual members [1]. Within the scope of the research presented here, the large-format additive manufacturing of formwork (3DPF) using the robotic fused layer process was investigated and used as a basis for the simulation-based and production-ready splitting of given concrete structures into individual modules.
