Porous alumina ceramics have many superior properties, such as high-temperature resistance, corrosion resistance, and low thermal conductivity. Alumina ceramics with solid and hollow lattices were prepared by a digital light processing (DLP) 3D printing technique. Stable alumina ceramics were sintered at 1 550℃ for 4h. The experimental results show that alumina ceramic with the solid lattice has a higher compressive strength rather than that with the hollow lattice, and the maximum compressive strength of alumina ceramic with the solid lattice is 4.80 MPa. The maximum compressive strength of the ceramic with the hollow lattice is 1.59 MPa. The results of mechanical tests are similar to the simulation data. Alumina ceramic with the hollow lattice formed by DLP technique can be used in industrial thermal insulation applications.
