3D printed functional ceramic has enormous application prospects in many fields such as construction,industry,aerospace,especially in the field of medicine.Relative to conventional 3D printed polymer and metal materials,3D printed ceramichasthe advantages of high temperature capability,high strength and stable physical and chemical properties.Among 3D printed ceramic materials,beta-tricalciumphosphate(β-TCP) is a promising candidate thanks to its no variability and good biocompatibility[1].At present,however,there is few research conducted a systematic research on 3D printed ceramic material,and technical problems like material proportion and post processing still needs to be solved.In this article,high quality β-TCP powders for3D printingwere successfully fabricated by solid state method.And the effect of silica doping on the properties of powders was investigated thoroughly in order to further improve the properties ofβ-TCP ceramic powders.As is shown in Fig.1,it is obvious that the average particle sizes decreased as the with the increasing amount of silica doping,andthe dispersity of as prepared β-TCP powders dramatically optimized when the silica doping concentration reached to 1 wt.%,indicating that silica is a promising activatorto further improve the propertiesβ-TCP powders for 3D printing.
