摘要：
Photosensitive Al2O3-resin slurries with high solid loading, low viscosity used for stereolithography based additive manufacturing were prepared in this paper. The dispersion behavior and rheological behavior of the Al2O3-resin slurries were studied by rheology observation and sedimentation tests. The dispersant type, concentration and solid loading had significant effects on the rheological behavior and stability of the photosensitive Al2O3-resin slurries. A long term stability and homogeneity slurry was obtained when the dispersant and concentration were KOS110 and 5 wt%, respectively. The Al2O3 slurry prepared with a high solid loading up to 60 vol%, low viscosity of 15.4 Pa s at 200s(-1) was chosen for stereolithography based additive manufacturing.
