Special Issue Information

Dear Colleagues,

Additive manufacturing (AM) has emerged as a novel technology for the design and fabrication of advanced ceramics and composites with complex structures and novel features. Significant progress has been achieved in the AM processing of ceramic materials and composites in recent years. Specifically, laminated object manufacturing (LOM), fused deposition modeling (FDM), selective laser melting (SLM) and photopolymerization represent some noteworthy technological examples. This Special Issue aims to explore state-of-the-art processing technologies, applications and challenges, and evaluate the potential application of AM in ceramics and composites. This Special Issue welcomes contributions addressing a range of topics related to ceramics and composites with elaborately designed components, structures and configurations; this includes, but is not limited to, the AM processing and property regulation of oxide; nitride and carbide ceramics; glass ceramics; and composites. Furthermore, this Special Issue welcomes submissions that address methodologies regarding the design and advanced characterization of this technology, as well as its specific applications.

This paper examines the application of non-synthetic particle suspensions as a support medium for the additive manufacturing of complex doubly curved ceramic shells with overhangs between 0° and 90° using clay paste. In this method, the build-up material is injected within a constant volume of air-permeable particle suspension. As the used clay paste does not solidify right after injection, the suspension operates like a support medium and enables various print path strategies. Different non-synthetic suspension mixtures, including solid and flexible components such as quartz sand, refractory clay, various types of wood shavings, and cotton flocks, were evaluated for their ability to securely hold the injected material while allowing drying of the water-based clay body and its shrinkage. The balance between grain composition, added water, and the compressibility of the mixture during printing and drying played a pivotal role in the particle suspension design and assessment. Furthermore, the moisture absorption of the particle suspension and the structural integrity of the layer bond of the fired ceramics were also assessed. The examined additive manufacturing process not only enables the production of meso-scale doubly curved ceramic shells with average overhang of 56° but also introduces a new practice for designing specialized surfaces and constructions.

The sintering of high-performance ceramics with complex shapes at low temperatures has a significant impact on the future application of ceramics. A joint process of digital light processing (DLP) 3D printing technology and a nitrogen-gas pressure-assisted sintering method were proposed to fabricate AlN ceramics in the present work. Printing parameters, including exposure energy and time, were optimized for the shaping of green bodies. The effects of sintering temperature, as well as nitrogen pressure, on the microstructure, density, and thermal conductivity of AlN ceramics were systematically discussed. A high thermal conductivity of 168 W·m−1·K−1 was achieved by sintering and holding at a significantly reduced temperature of 1720 °C with the assistance of a 0.6 MPa nitrogen-gas pressure. Further, a large-sized AlN ceramic plate and a heat sink with an internal mini-channel structure were designed and successfully fabricated by using the optimized printing and sintering parameters proposed in this study. The heat transfer performance of the ceramic heat sink was evaluated by infrared thermal imaging, showing excellent cooling abilities, which provides new opportunities for the development of ceramic heat dissipation modules with complex geometries and superior thermal management properties.
