碩士 === 國立臺北科技大學 === 機電整合研究所 === 105 === This study, dissertates the Vat Photopolymerization Process for Ceramic (VPPC) system with solvent-free slurry, utilized to large-size ceramic workpieces with a hollow structure. It utilizes a light source to cure the slurry to form three dimensional parts. By using Bottom-Up approach and solvent-free slurry, there occurs very less wastage and the slurry is reusable. The VPPC system is configured with two Full HD projectors to generate a build volume of 128mm*114mm*150mm in length, width and height. It also consists of a scraper installed on X-axis platform to clean the uncured slurry from the bottom of the tank. The viscosity of the solvent-free slurry is adjusted to 1000cP (5rpm) to attain a good fluidity. By optimizing different parameters, the shortest time achieved to form each layer is 15 seconds. This research also discusses in depth about the process, system design, control system, PC interface setting, image deformation correction and followed by benchmark tests. The VPPC system has shown the capability in fabricating the hollow structures. This study can also adapt different ceramic materials and produce tailored mechanical properties of the resultant parts. This process also can be utilized to fabricate the biomimicking bone implants or similar lattice structures. By using biocompatible ceramic materials, the implant structures not be used for prototyping but also be used for implant surgeries.
