Abstract：The ceramic slurry with 55vol％ solid phase content was prepared with micron calcium silicate／β-tricalcium phosphate powder，photosensitive resin，dispersant and photoinitiator．The effect of the amount of dispersant on the viscosity of ceramic slurry was studied．The debinding and sintering processes of calcium silicate／β-tricalcium phosphate ceramic green body were explored．The influence of sintering temperature on the properties of ceramics was studied．The results show that the calcium silicate／β-tricalcium phosphate bioceramics with micron and submicron microporous structures are prepared by sintering at 1 100℃，and the open porosity is 33．5 1％，cumulative density is 2．01 g·cm-3，bending strength is 26．97 MPa．
Key words：bioceramic；stereolithography；ceramic slurry viscosity；3 D printing ceramic sintering
