“…A major concern at that time was, however, the deposition of uniform layers with a flat and smooth surface. Since then, technologies capable of repeatedly depositing thin layers of ceramic slurries to build up dense powder beds for S‐3DP and S‐SLS have been developed . A survey of recently published work reveals a great potential of this technology for the manufacture of dense powder compacts, comparable to those produced by classical powder processing, that is with low organic content.…”

“…In this context, one of the most successful technologies is stereolithography (SL), using ceramic slurries containing photosensitive resins for the layerwise buildup of ceramic compacts. So far, little work has been devoted to the development of AM processes for the deposition of thin layers using water‐based ceramic suspensions or pastes with low organic content …”

“…So far, little work has been devoted to the development of AM processes for the deposition of thin layers using water-based ceramic suspensions or pastes with low organic content. [70][71][72] Slurries facilitate the use of powders with a size ranging from <100 nm to >100 lm, and classical ceramic processing know-how can be applied for their preparation. Moreover, interparticle interactions can be very well controlled and the mobility of particles within the slurry enables their free settling, both a prerequisite for an effective powder packing.…”

Additive manufacturing (AM) is a technology which has the potential not only to change the way of conventional industrial manufacturing processes, adding material instead of subtracting, but also to create entirely new production and business strategies. Since about three decades, AM technologies have been used to fabricate prototypes or models mostly from polymeric or metallic materials. Recently, products have been introduced into the market that cannot be produced in another way than additively. Ceramic materials are, however, not easy to process by AM technologies, as their processing requirements (in terms of feedstock and/or sintering) are very challenging. On the other hand, it can be expected that AM technologies, once successful, will have an extraordinary impact on the industrial production of ceramic components and, moreover, will open for ceramics new uses and new markets.

“…The VAT process was initially developed for polymeric materials; however, in recent years, there has been an increase in the manufacturing of ceramic parts using this technology. 19,[25][26][27] Chartier et al 28 have investigated the use of SLA for manufacturing ceramic structures and have demonstrated successful production of detailed and precise complex lattice systems. [21][22][23][24] Thus, the use of Stereolithography (SLA), based on photopolymer resins with suspended ceramic particles (by at least 40% volume) appears to be an alternative technology for producing complex 3D printed ceramic parts.…”

In this work, metal-ceramic composite parts based on aluminum and alumina were manufactured in a two-stage process. First, silica was printed using a vat photopolymerization technique, followed by a curing and sintering stage, which resulted in ceramic precursors. Subsequently, these samples were subjected to a metal infiltration process to form interpenetrating metal-ceramic composites (IPCs). These composites have attracted considerable attention in the aerospace and defense sector due to the ductility associated to the metal phase and the strength offered by the ceramics. A novel application with utility includes composite tooling which requires a low coefficient of thermal expansion (CTE) for high temperatures. The investigated specimens were tested for surface quality and shrinkage, followed by a mechanical characterization. It was recorded that the samples presented a 12%-18% of shrinkage after the sintering process. The mechanical testing showed that the hardness, compression, and flexural strength of the composites were superior to the printed and sintered ceramics. A thermal analysis on the composite showed that its CTE is more than two times lower than the common composite tooling materials. It is expected that the present work can provide the foundations for further studies on these systems in the refractory, automotive, and armor-based fields.
