Ceramic materials have many characteristics including high strength, wear and corrosion resistance and high temperature resistance, which are favorable for the applications of aerospace, biomedicine, and electronic information, etc. However, the fabrication of complex-shaped ceramic parts has become a great challenge. Additive manufacturing (AM) is believed to be an effective solution to resolve this issue. In this paper, ceramic materials for AM and their forming technologies were introduced. According to the different forms of ceramic materials for AM, ceramic materials for AM could be divided into four categories: powder, filament, sheet and slurry/paste. On this basis, several mainstream ceramic AM technologies and their applications, such as selective laser sintering (SLS), selective laser melting (SLM), three-dimensional printing (3DP), fused deposition manufacturing (FDM), laminated object manufacturing (LOM), stereolithography (SL), digital light processing (DLP) and direct ink writing (DIW), were detailedly discussed. Finally, according to the up to date researches on AM of ceramics, the future prospects for ceramic materials for AM and their forming technologies were carried out.
