摘要
针对传统陶瓷3D打印存在打印效率低和成型件具有各向异性的不足和局限性,提出一种连续面曝光陶瓷3D打印新工艺,通过采用自主研发的复合富氧膜并结合配制的树脂基陶瓷浆料实现陶瓷素坯件的连续打印.阐述连续面曝光陶瓷3D打印的基本原理和工艺流程;研究陶瓷浆料的配制,并利用搭建的实验平台揭示了关键工艺参数对成形过程的影响和规律;最后,结合优化的工艺参数,通过两个典型案例(镂空件和薄壁件)连续3D打印,以及所打印的素坯件经脱脂烧结后性能的表征和测试,证实了提出方法的可行性和有效性.实现了陶瓷零件连续3D打印工艺,为探索高效、低成本连续陶瓷3D打印提供了一种全新的解决方案.
In order to resolve the problems of the low efficiency and the anisotropy of printed object in the traditional ceramic 3D printing techniques, a novel continuous digital light processing(DLP) ceramic 3D printing implemented by utilizing the combination of an oxygen-rich composite thin film and the resin-based ceramics slurry has been proposed and developed. The basic principle and the process flow of the proposed continuous ceramic 3D printing are described. Then, the ceramic slurry used for this proposed 3D printing technique is investigated and optimized, and the effects and the rules of primary process parameters on forming process are revealed by conducting a series of experiments. Finally, two typical cases are provided to demonstrate the feasibility and validity of the proposed process. As a result, a continuous DLP ceramic 3D printing has been fulfilled, which provides a promising and novel solution for high-efficiency, low-cost ceramic 3D printing.
