目的：研究增材制造（AM）技术制备的氧化锆材料的力学性能和表面性能，以及制备方向对其力学性能和表面性能的影响。方法：采用基于立体光刻（SLA）原理的ZrO2浆料（3DMix ZrO2; 3DCeram）和三维打印系统（CeraMaker 900; 3DCeram）制备标本。在平行、对角线和垂直3个构建方向上，评价了氧化锆的力学性能（抗弯强度、维氏硬度、断裂韧性、弹性模量和泊松比）和表面性能（化学成分和表面观察），探讨了构建方向与氧化锆力学性能和表面性能各向异性之间的关系。统计分析采用单因素方差分析和Tukey's诚实显著性差异检验。结果：竖向建筑方向弯曲强度最高。垂直方向的抗弯强度显著高于平行和对角方向；在对角线方向上也显著高于平行方向(p
Purpose:This study investigates the mechanical and surface properties of zirconia manufactured using additive manufac-turing (AM) technology and the effect of the building direction on the mechanical and surface properties.Methods: Specimens were prepared using ZrO2 paste (3DMix ZrO2; 3DCeram) and a three-dimensional printing sys-tem (CeraMaker 900; 3DCeram) based on the principles of stereolithography (SLA). The mechanical properties (flexural strength, Vickers hardness, fracture toughness, elastic modulus, and Poisson's ratio) and surface properties (chemical com-position and surface observation) were evaluated for three building directions (parallel, diagonal, and perpendicular) to investigate the relationship between the building directions and the anisotropy of the mechanical and surface properties of SLA-manufactured zirconia. Statistical analysis was performed using a one-way analysis of variance and Tukey's honestly significant difference test.Results: The highest flexural strength was obtained for a perpendicular building direction. The flexural strength was significantly higher in the perpendicular direction than in the parallel and diagonal directions; it was also significantly higher in the diagonal direction than in the parallel direction (p
