This was largely displaced by the first industrial revolution and replaced by industrialized building materials such as concrete. With the fourth industrial revolution and the growing awareness of the impact of resource waste and waste production on the environment, traditional earthen construction is set to regain economic momentum through digitization and automation. Building with clay offers the opportunity for a systematic transformation of the construction industry towards carbon neutrality. Currently, the construction industry is responsible for more than 30\% of global greenhouse gas emissions. This could change in the future by using regional, circular materials that are ideally obtained from the construction site itself. Clay occurs extensively and abundantly in almost all parts of the world and can be supplemented with various regionally available additives. Through product standardization and technological advances, earthen construction could be mass produced and compete with conventional reinforced concrete construction or timber construction in the future. This master thesis focuses on the modernization of earthen buildings in the form of digitized and automated additive manufacturing processes such as rammed earth construction or 3D printing with clay for wall components. The aim of the master thesis is to develop a technical design for one of the mentioned additive manufacturing processes. In order to achieve this goal, the different manufacturing processes and types are compared according to the state of the art. The best evaluated one is chosen. Exemplary investigations using a clay 3D printer serve as a practical basis for the choice of manufacturing process. In the process, test specimens are printed with and without additives, also there are test specimens created with different degrees of filling. The specimens are tested in the laboratory for their compressive strength. The following work shows the many potentials of earthen building as a circular and modern construction method, while also shedding light on the challenges that still need to be solved.}, language = {de} }
