Fabrication of Complex Three-Dimensional Structures of Mica through Digital Light Processing-Based Additive Manufacturing

Mica is a group of clay minerals that are frequently used to fabricate electrical and thermal insulators as adsorbents for the treatment cationic pollutants. However, conventional subtractive manufacturing has drawback poor three-dimensional (3D) shape control, which limits its application. In this study, we propose digital light processing (DLP)-based additive (AM) one most effective ways address drawback. Two major challenges ceramic DLP process production homogeneous stable slurry with required rheological properties maintenance printing precision. The mica green body was fabricated using 53 vol.% solid loading through DLP, exhibited good dimensional resolution under an exposure energy dose 10 mJ/cm2. precise, complex 3D structure maintained without any defects after debinding sintering at 1000 °C. use AM overcome shape-control limitations demonstrated in study offers great potential expanding applications mica.
