Direct ink writing technology is conducive to molding personalized and customized products with complex structures. However, it is easy to produce pores and an-isotropic problems of mechanical properties when printing a dense solid structure. In this paper, Al2O3 was used as a raw material and a nozzle with a diameter of 2.0 mm was selected for direct ink writing. The results show that the layer height is 0.8 mm, the internal structure of the printed sample is relatively dense, and no pores appear after writing. Also, the mechanical properties parallel to/perpendicular to the inter-layer are similar, and the anisotropy index is close to 100%, thus alleviating the anisotropy problem of mechanical properties.
