Abstract

The stresses generated during ceramic vat photopolymerization can lead to significant dimensional deformation of the ceramic green body, severely limiting the practical application of this technology. In this work, the alternate projection method was successfully applied to ceramic vat photopolymerization for the first time. The effects of different alternate projection parameters on the accuracy and properties of the ceramic green bodies were compared. By optimizing the parameters and lattice skeleton, the low-deformation ceramic green bodies were successfully prepared. In addition, ceramic parts with complex structures were fabricated after thermal binder removal and sintering. Alternate projection optimization enables the preparation of high-precision ceramic parts without requiring modifications to the ceramic material or printing equipment. This method is highly practical and cost-effective, especially suitable for rapid iteration of high-precision complex structural parts, and can be widely used in semiconductor, aerospace, and other technical fields.

陶瓷槽光聚合中的替代投影优化

陶瓷大锅光聚合过程中产生的应力会导致陶瓷绿体发生明显的尺寸变形，严重限制了该技术的实际应用。本文首次成功地将交替投影法应用于陶瓷大桶光聚合。比较了不同交替投影参数对陶瓷绿体精度和性能的影响。通过优化参数和晶格骨架，成功制备了低变形陶瓷绿体。此外，通过热去除粘结剂和烧结制备了结构复杂的陶瓷零件。交替投影优化使高精度陶瓷部件的制备不需要修改陶瓷材料或打印设备。该方法实用性强，性价比高，特别适用于高精度复杂结构件的快速迭代，可广泛应用于半导体、航空航天等技术领域。
