Pores is one of the most defects during laser additive manufacturing of ceramic material. In this paper, different structures of Al2O3–ZrO2 ceramics are deposited by using powder-feeding laser additive manufacturing. The ceramic structures can be simplified into three typical structures: linear-type, face-type and body-type structure. The formation mechanism and quantitative analysis of pores in different ceramic structures are studied. The pores of ceramic structure is mainly divided into four types: intercrystalline pore, interlayer pore, in...
