Project content According to the current state of the art, bricks are manufactured using the extrusion process. This limits the shape and load-bearing capacity of the bricks. Since considerable compressive, tensile and combined loads act on building supports for structures with more than 6 storeys, brick building supports must be so large that they become uneconomical. These limitations take business out of the brick market. A systematic approach that combines the accuracy of additive manufacturing with the advantages of the ceramic material will be used to develop slender, economical and practical masonry building columns for structures > 6 storeys. 3D printing enables larger bodies, arbitrary geometries and the integration of an interlock and prestressing system into the building support. The result is hybrid bodies that can optimally withstand the high loads. In addition to geometries, materials and the building support itself, the ability to assemble the brick elements into a building support and a transport system must also be developed. New test methods are being developed for the static tests.
