Additive manufacturing of ceramic materials has been the focus of conferences for years. The manufacturing possibilities lead to the presentation of new types of products. Micro- and power electronic components are a broad field of application for additively manufactured components. Here, the LCM process, which enables components based on anisotropic voxels with high geometric complexity, is one of the most promising manufacturing technologies. In order to ensure improved materials performance, the directional dependence of the dielectric properties has to be investigated, among. In doing so, the investigations are supported by µ-CT images, which for the first time allow 100% control of structural defects such as pores, cracks and surface defects.
