In every field of engineering, the material used plays a central role in the design of structures and components. Additive manufacturing allows more freedom in design than with conventional manufacturing methods. 3D printing is also becoming increasingly important in many sectors, including the construction industry. The material of choice is concrete. However, concrete has the property of shrinking and possibly deforming or warping during curing. These material-related problems could be solved with the use of 3D printing. They can be compensated by specific pre-deformations. The goal of this work is to characterize these deformations and to work out suitable pre-deformations and verify them with test prints. In addition, it is necessary to make adjustments to the control of the 3D printer in order to print nonplanar and curved geometries.     «
