Three-dimensional (3D) printing of ceramics has gained widespread attentions in recent years. Many excellent reviews have reported the printing of ceramics. However, most of them focus on printing of dense ceramics or general ceramic aspects, there is no systematical review about 3D printing of porous ceramics. In this review paper, the 3D printing technologies for fabricating of porous ceramic parts are introduced, including binder jetting, selective laser sintering, direct ink writing, stereolithography, laminated object manufacturing, and indirect 3D printing processes. The techniques to fabricate hierarchical porous ceramics by integrating 3D printing with one or more conventional porous ceramics fabrication approaches are reviewed. The main properties of porous ceramics such as pore size, porosity, and compressive strength are discussed. The emerging applications of 3D printed porous ceramics are presented with a focus on the booming application in bone tissue engineering. Finally, summary and a perspective on the future research directions for 3D printed porous ceramics are provided. 相似文献

Coal fly ash (CFA) is a solid waste generated by coal-fired power plants, and its massive accumulation problem needs to be solved urgently. There are many ways of resource utilization of CFA, but the applications of high added value are rare. Preparation of porous materials is an effective way to realize its high value-added applications. In this paper, porous materials are divided into ceramic membranes, thermal insulation materials and adsorption materials according to application fields. The research progress of porous materials prepared from CFA and used for filtration, thermal insulation and adsorption is reviewed. Ceramic membranes can filter different types of wastewater from different industries at different levels. Thermal insulation materials, with relatively low added value though, are easier to achieve large-scale production. Zeolites, geopolymers and various composite materials are crackerjack adsorbents, which can effectively purify wastewater and exhaust gas. After summary, comparison and discussion, it is concluded that ceramic membrane is the most ideal and feasible material to realize high value-added application of CFA among the three porous materials. Finally, the existing problems and future prospects of the three porous materials are stated. 相似文献
