AB - Microceramic injection molding (µCIM) has shown great potential in making small-scale intricate near-net-shape parts with the competitive price for mass production. In this study, multi-exposure multi-development UV-Lithographie, Galvanoformung, Abformung (LIGA), µCIM, variothermal temperature control, and Taguchi experimental method are integrated and applied to develop a multilayer micropart with zirconia (ZrO2) feedstock. With the variothermal temperature control, a 335 μm thickness multilayer micropart having 100 microholes of 21.6 μm in diameter has been successfully molded. Optimization of the molding parameters to achieve high microhole replication quality molding was carried out with Taguchi experimental method. Results from Taguchi experiments reveal that mold temperature (40.9%), back pressure (31.8%), and injection speed (26.8%) contribute most to the replication quality, while ejection temperature has little effect on it. After further sintering processing, the thickness of the part is 200 μm, the final microhole diameter is 17.3 μm and its depth is 35.3 μm while the width of the channel is 38.5 μm and its height is 35.3 μm, and the accumulated aspect ratio of the dual layer structure is 2.95.
