    Prospects for using 3d printing to form ceramic membranes: a brief review
    (КПІ ім. Ігоря Сікорського; ТОВ «Українська водна спілка», 2024) Diachenko, Anastasiia; Hutsul, Khrystyna; Dontsova, Tetiana
    The article presents a discussion of the potential applications of 3D printing in the formation of ceramic membranes. In recent years, additive technologies for ceramic materials have become a prominent area of research, suggesting that they can be effectively employed to design and produce hierarchical porous ceramic structures, combining flexible design and advanced approaches to their formation. The objective of this paper is to analyse the potential of additive technologies for the production of ceramic membranes, identify the most promising technologies, and provide a comprehensive evaluation of their achievements, challenges, and limitations. The present study considers seven principal additive manufacturing processes, which are based on the utilization of diverse 3D printing technologies. It is demonstrated that the most promising technologies for the manufacture of ceramic membranes are currently Vat Photopolymerisation, which enables the production of products with complex geometry and high accuracy, and those that utilize Powder Bed Fusion processes, which ensures the mechanical strength and density of ceramic products. The article presents an analysis of the printing parameters of Stereolithography, Liquid Crystal Display and Selective Laser Sintering technologies, and their potential for the production of ceramic products in general and membranes in particular. The problems and challenges of creating ceramic membranes by 3D printing, such as optimization of the composition of ceramic suspensions and post-processing of products, are noted. Possible ways to solve them are discussed, including the improvement of printing materials and technological processes. The prospects for the use of the obtained ceramic membranes in various industries are also considered. The directions of further research aimed at improving additive technologies for printing ceramic membranes and expanding their application in industry are identified.
