Concrete has advantageous properties and is therefore, from a quantitative point of view, by far the most used construction material worldwide. This in combination with the amount of emissions arising, especially within the cement production, makes it a relevant factor regarding environmental pollution. With high labour and low material costs the material utilisation regarding structural properties shows great potential for improvement. In addition, the transformation of the society away from craftsmanship towards higher digitisation and automation must finally also impact the still low level of automation in the construction industry. Structural optimisation, apart from other approaches like optimising the material itself, to reduce the required material and improve the environmental performance, is essential for the future development within the sector. Unfortunately, the production of these kind of structures is still very expensive, yet automated manufacturing processes could have the potential to enable an economic production. Therefore, the authors started to develop a disruptive automated production process for structurally-optimised concrete components, using 6-axis industrial robots for placing and stripping the formwork. The system consists of various elements that can be assembled and extended as required. The geometry is adjustable to the openings predefined by the topology optimisation, with certain limitations set according to design. A literature study followed by a parametrical investigation of the existing formwork solutions further defined focus points for the development. Preliminary tests of the shuttering system in regard to the fillets and the longitudinal elements of the kit were conducted using different materials to assess the interaction with the concrete, the stripping by a robot and the placement accuracy. Further steps include a performance analysis and large-scale testing of the automated production process. The first tests have already been carried out and show promising results for further investigation and testing, especially for the system by itself including the flexibility and the used materials.
