Laser additive manufacturing of Al2O3 and ZrO2-based eutectic ceramic oxide: An overview

This review aims to summarize fundamental aspects and recent progress in the production of eutectic ceramic oxide systems, specifically Al 2 O 3 /ZrO 2 systems, using laser additive manufacturing technologies (LAM). As is well-known, the building process of ceramics in LAM carries certain challenges, including the development of thermal stresses, crack formation, and distortion of the samples. Due to these challenges, this review focus on the recent advancements in laser printing of Al 2 O 3 and ZrO 2 based eutectic ceramic oxides. Key process parameters and material properties are thoroughly discussed, with special attention given to critical factors such as characteristics of ceramic powders and printing parameters. In conclusion, this review provides a set of guidelines, along with relevant data, to support the development of ceramic eutectic systems using LAM techniques, such as Laser Powder Bed Fusion (L-PBF) and Direct Energy Deposition (DED). • Production of Al 2 O 3 based directionally solidified eutectics ceramics by LAM • Al 2 O 3 -based ceramics process necessitates precise control over process parameters. • The absorptivity of the ceramic material by the laser is one of the most important factor. • Crucial role of both process parameters and material properties
