Binder Jetting Additive Manufacturing Of Ceramics: A Literature Review

Ceramic materials are more difficult to process than metals and polymers using additive manufacturing technologies because of their high melting temperature, high hardness and brittleness. Binder jetting additive manufacturing has been used to fabricate ceramic parts for various applications. This paper presents a literature review on recent advances in ceramic binder jetting. The paper begins with listing applications and material properties investigated in reported studies followed by the effects of raw materials and process parameters on resultant material properties. Raw materials include binder (material, application method, concentration, and saturation) and ceramic feedstock (preparation method, quality metrics, and particle size and shape), and process parameters include layer thickness and postprocessing method. Resultant material properties of interest include density, strength, hardness, and toughness. This review will provide guidance for the selection of raw materials and process parameters to obtain desired material properties for various applications. This paper is concluded by proposing future research directions.
