Wet-extruded compounds used in Liquid Deposition Modeling (LDM) pose a challenge in the manufacturing process due to their sustained plasticity. The printed object does not match the digital CAD model. Deformations and geometry constraints limit the design process. Perforations and material overhangs can only be produced to a certain extent. Furthermore, material-specific properties and user influence play a decisive role in the implementation. At the same time, precise manufacturing processes using digital models are comparatively fast, cost-effective, and sustainable. In industry and construction, they enable a new look at established and material-related design and shaping.

In order to be able to control the deformation behaviour and process-typical limitations in the production process, a ceramic composite material is being developed within the project which can be controlled via an electromagnetic field. The material should be stabilized and reshaped by equipment modification. The electromagnetic shaping of ceramics (=EMUK) allows for the first time the design of overhangs and perforations according to the model and without support structures. The extension of the processable materials to Al2O3 also promises a wide range of technical applications.
