Abstract: The process of photoresensitive resin binder jetting additive manufacturing ZrO₂ green part was investigated. By jetting the photoresensitive resin binder, the UV light source induced the photoresensitive resin cross-linking and bonded ZrO₂ powder, and the green part was formed, which had sufficient strength for direct post-processing without thermal curing. Then, the green part was sintered in air atmosphere at 1200, 1400 and 1600℃ to remove the cured photosensitive resin and realize the sintering between the powder particles. The effects of the layer thickness and sintering temperature on the dimensional accuracy, relative density, apparent porosity, phase composition and mechanical properties of the green part and sintered part were investigated. The results show that with the increase of the powder thickness, the diffusion effect of photosensitive resin adhesive leads to the deterioration of the green part's dimension accuracy, the relative density of the green part decreases, the apparent porosity increases and the compressive strength decreases. With the increase of sintering temperature, the shrinkage of sintered parts becomes larger, the relative density becomes bigger, the phase composition remains unchanged, and the mechanical properties are greatly improved compared with those before sintering. When the green part formed at 100 滋m of layer thickness is sintered at 1600 ℃ for 4 h, it has the best parameters with the relative density of 57%, the apparent porosity of 21.4% and the compressive strength of 62.9 MPa.
