“…First, partial delamination at the interface occurred ( Fig. 4a and c): during the drying process, the built-up layer bent upwards at its perimeter, and since the adhesion of the single layers proved superior to the adhesion between the green body and the substrate [20], the green body was separated from the substrate. Furthermore, the high solid content caused an enhanced risk of blocking the nozzle of the airbrush system, which involved serious problems from a technological viewpoint.…”

“…The present work addresses to the first of these two challenges, investigating the feasibility of a glass-derived coating by airbrush spraying of SiO 2 -CaO-Na 2 O-Al 2 O 3 (SCNA) glass powder suspensions followed by thermal treatment. Airbrush spraying of ceramic slurries is a versatile method that allows the coating of substrates having complex shape with an adequate control of coating thickness [17][18][19][20]; however, there is a paucity of studies about its use in the field of bioceramics. Very recently, Pardun et al reported the characterization of wet nanopowder-sprayed zirconia/HA composite coatings on dental implants (screws) [21].…”

“…Waetjen et al [91] investigated slurry deposition by means of an airbrush for direct SLS of alumina and zirconia parts. It was possible to generate dense powder beds with densities of up to 98% using conventional sintering in a furnace at 1500°C for 2 h. However, selective laser sintering of these powder beds was not possible, which was ascribed to the lack of the liquid phase.…”

This paper offers a review of present achievements in the field of processing of ceramic-based materials with complex geometry using the main additive manufacturing (AM) technologies. In AM, the geometrical design of a desired ceramic-based component is combined with the materials design. In this way, the fabrication times and the product costs of ceramic-based parts with required properties can be substantially reduced. However, dimensional accuracy and surface finish still remain crucial features in today's AM due to the layer-by-layer formation of the parts. In spite of the fact that significant progress has been made in the development of feedstock materials, the most difficult limitations for AM technologies are the restrictions set by material selection for each AM method and aspects considering the inner architectural design of the manufactured parts. Hence, any future progress in the field of AM should be based on the improvement of the existing technologies or, alternatively, the development of new approaches with an emphasis on parts allowing the near-net formation of ceramic structures, while optimizing the design of new materials and of the part architecture.

“…With integrated processes such as laser powder bed melting, currently the approach still faces various challenges, e.g., the difficulty of performing direct sintering of ceramic powder and the existence of thermal residual stress-induced cracks. 15,16 On the other hand, although the multi-step process approach often results in increased fabrication time and costs, it takes advantage of the extensive knowledge base of traditional ceramic manufacturing techniques such as sintering and slip casting, therefore posing less technical challenges for application development.…”

Custom ceramic structures possess significant potentials in many applications such as dentistry and aerospace where extreme environments are present. Specifically, highly customized geometries with adequate performance are needed for various dental prostheses applications. This paper demonstrates the development of process and post-process parameters for a dental porcelain ceramic material using binder jetting additive manufacturing (AM). Various process parameters such as binder amount, drying power level, drying time and powder spread speed were studied experimentally for their effect on geometrical and mechanical characteristics of green parts. In addition, the effects of sintering and printing parameters on the qualities of the densified ceramic structures were also investigated experimentally. The results provide insights into the process-property relationships for the binder jetting AM process, and some of the challenges of the process that need to be further characterized for the successful adoption of the binder jetting technology in high quality ceramic fabrications are discussed.
