Abstract In this study, we developed a unique defect healing method for 3D printed ceramic compact via cold isostatic pressing ( CIP ) after debinding, and typical features of interlayer interface defects 3D‐printed zirconia were characterized found to be reduced significantly. The characteristic sintering kinetics window microstructure evolution the healed sintered bodies systematically investigated, which was quite different from conventional shaping methods. three stages are probed by their feature details such as mechanically flattening surface at early stage, heterogeneous high porosity in region middle slightly ripple‐like structural combined with final stage. pore structure traced mechanical properties Young's modulus, hardness, fracture toughness measured understand significance heal effect.
