| Abstract Scope |
Vat-photopolymerization-based additive manufacturing of ceramics has become increasingly popular due to its capability to fabricate geometrically complex components with high spatial resolution and high sintered density. However, developing suitable ceramic slurries remains a key challenge due to delicate balance of material properties required for successful printing and post-processing. Moreover, slurries optimized for one machine often perform poorly on others, as print performance is sensitive to differences in hardware and process parameters. As such, slurries with tunable rheological and photoreactive properties are highly desirable. In this study, we demonstrate the use of ethoxylated acrylate-based organic monomers as a foundation for preparing alumina slurries. These slurries exhibit strong photo-reactivity under blue light (460 nm) exposure and possess excellent rheological characteristics that can be tailored by selecting monomers of varying molecular weights. This approach offers a flexible platform for designing high-performance ceramic resins compatible with a wide range of printing systems. |
