| Abstract Scope |
Binder jetting additive manufacturing has enabled enormous design freedom and formed new fabrication paths for advanced ceramic materials. Therefore, this promising technology has been utilized in various application scenarios, in which both mechanical and thermal properties of the printed and densified parts are of high interest. This study investigated the effects of the bimodal particle size distribution of a SiC feedstock powder on the mechanical and thermal properties of densified SiC-Si composites printed from binder jetting additive manufacturing. The bimodal SiC powder was prepared by mixing two unimodal powders. Printed parts from both powders were densified liquid silicon infiltration (LSI). Resultant relationships in terms of green density, densified density, flexural strength, and thermal conductivity were studied among the densified parts from both bimodal and unimodal feedstock powders. |
