Rapid Prototyping of microstructured ceramic and metal parts by Powder Fused Deposition modeling

这项名为粉末熔融沉积成型微结构陶瓷和金属部件快速成型的提案的主要目标是开发一种新的工艺链，用于实现范围小于100微米的具有几何特征的陶瓷或金属部件。关键问题是fdm工艺的进步，使新的工艺链粉末熔融沉积成型能够直接制造烧结陶瓷或金属部件。由粘结剂混合物、添加剂和陶瓷或金属填料、3D打印和热后处理组成的各个步骤的模塑材料的开发必须进行全面的研究。主要的结果是，除了成功地印刷致密和无缺陷的微结构陶瓷或金属部件外，还必须评估工艺参数与器件性能之间的相关性，以从中得出设计规则。

The main objective of this proposal entitled Rapid Prototyping of microstructured ceramic and metal parts by Powder Fused Deposition modeling is the development of a novel process chain for the realization of ceramic or metal components with geometric features in the range of less than 100 µm. Key issue is the advancement of the FDM process enabling the direct fabrication of sintered ceramic or metals parts by the new process chain Powder Fused Deposition Modeling. The indi-vidual steps moulding material development, consisting of a binder mixture, additives and ceramic or metal fillers, 3D-printing, and thermal postprocessing have to be researched comprehensively. As a main result, besides the successful printing of dense and defectfree microstructured ceramic or metal parts, correlations between the process parameters and device properties have to be evaluated, from which design rules can be derived.
