Rapid prototyping of functional demonstrators for integrated ceramic components using microfluidics and electrophoretic deposition

利用现有的快速成型方法(RPT)可以制造出具有复杂几何形状的集成陶瓷器件。然而，与系列化元件的生产技术(如多层技术)相比，所有的快速成型方法都有明显的缺点。因此，可以为新设备生产实验室演示器，但它们的功能性能无法与系列组件相比较。在本项目中，这一缺点将被一种新的方法克服：微流控和电泳法的结合。使用微流体将实现结构和材料的选择，而电泳沉积提供了均匀微结构的形成。新方法的性能将通过制作不同材料的模型样品来演示。为此，将开发一种实验室设备，并确定合适的工艺参数。将通过多尺度模拟来模拟和优化电泳沉积过程中的微结构形成。结构模型样品的烧结特性将有助于深入了解共烧过程中的烧结现象。

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.
