Abstract Scope |
This study focuses on the fabrication of transparent Yttria polycrystalline ceramics using a Hyrel Systems 30M printer and an EMO-25 extruder for Direct Ink Writing (DIW) 3D printing with the combination of vacuum sintering and other post-sintering methods. This Yttria powder was homogenously mixed with water-soluble copolymer isobutylene and maleic anhydride ISOBAM-104 (ISO-104) as a dispersant/gelling agent and DI water as a medium. Various recipes were systematically created and characterized in order to create a quality suspension. Following printing the samples undergo different stages of processing to achieve a fully dense and transparent product including drying, burnout, vacuum sintering, and polishing for transmittance testing in the UV-Vis/IR spectrum range. Utilizing this posting printing processing stages and the high customizability of computer modeling with DIW suspension printing the fabrication of transparent ceramic that not only matches conventional CIP methods but offers the freedom to design complex shapes without restraint. |
