Integrated ceramic devices with complex geometry can be produced using existing rapid prototyping methods (RPT). Yet, all rapid prototyping methods have significant disadvantages compared to production technologies for serial components (e.g. multilayer technology). So laboratory demonstrators can be produced for new devices but their functional performance cannot be compared with serial components. In the present project this disadvantage will be overcome by a new approach: the combination of microfluidics and electrophoretic forming. Using microfluidics the structuring and the material selection will be achieved, whereas electrophoretic deposition provides the formation of a homogeneous microstructure. The performance of the new method will be demonstrated by production of model samples of different materials. For that, a lab device will be developed and suitable process parameter will be identified. The microstructure formation during electrophoretic deposition will be modeled and optimized by multiscale simulation. Sintering properties of structured model samples will give insight into sintering phenomena during co-firing.

具有复杂几何形状的集成陶瓷器件可以使用现有的快速成型方法（RPT）来生产。然而，所有的快速成型方法都有显着的缺点相比，生产技术的串行组件（例如多层技术）。因此，可以为新设备生产实验室演示器，但其功能性能无法与串行组件进行比较。在本项目中，这一缺点将通过一种新的方法来克服：微流体和电泳成形的组合。使用微流体将实现结构化和材料选择，而电泳沉积提供均匀微结构的形成。新方法的性能将通过生产不同材料的模型样品来证明。为此，将开发实验室设备，并确定合适的工艺参数。在电泳沉积过程中的微结构形成将建模和优化多尺度模拟。结构化模型样品的烧结特性将使我们深入了解共烧过程中的烧结现象。
