Abstract Scope Ultra-high temperature ceramics (UHTC) and their composites (UHTCMCs) are of interest for use in harsh environments encountered by next-generation aerospace vehicles but are limited by their ability to be processed into complex-shaped components. A solution is through additive manufacturing (AM) via direct ink writing (DIW), which allows for the complex shaping of ceramics and composites with high feature resolution. To create complex ceramic shapes, shear-thinning, visco-elastic tailored inks are developed with both preceramic polymers and aqueous slurries and are extruded layer-by-layer. Each set of preceramic- or aqueous-based inks contained zirconium diboride (ZrB2), an UHTC, and various loadings of silicon carbide (SiC) chopped fibers. This study includes an analysis of the rheology and printability of inks and the effects of printing parameters on final ceramic development. Additionally, a description of ceramic conversion processing parameters is given, focusing on porosity comparison between preceramic and aqueous-based inks.
