The present article aims to explore the printability of scandia-stabilized zirconia ceramic parts using desktop and low-cost DLP 3D printer. The acrylate-based homogeneous slurries with zirconia powder stabilized by 6 mol.% of Sc₂O₃ (6ScSZ) and 10 mol.% of Sc₂O₃ and 1 mol.% of Y₂O₃ (10Sc1YSZ) were prepared with appropriate rheological and UV-curing properties. In comparison with yttria-stabilized zirconia, slurries filled with 6ScSZ and 10Sc1YSZ powders reviled lower viscosity at the same solid content. The cure depth of the suspensions was suitable to print the objects with 50 μm of layer thickness, good interlayers connection, and surface finishing. No critical defects in ceramics such as cracks or delamination were observed. Both ceramics have the Vickers microhardness value of 11 GPa and the high ionic conductivity up to 0.2 S/сm at 900 °C demonstrating that the DLP is a promising method of fabricating scandia-stabilized zirconia parts as electrolyte material for SOFC application.

本文旨在探讨使用台式机和低成本DLP 3D打印机的scan稳定氧化锆陶瓷零件的可打印性。具有6摩尔％Sc ₂ O ₃（6ScSZ）和10摩尔％Sc ₂ O ₃和1摩尔％Y ₂ O ₃稳定的氧化锆粉末的丙烯酸酯基均质浆料（10Sc1YSZ）具有适当的流变和紫外线固化性能。与氧化钇稳定的氧化锆相比，填充6ScSZ和10Sc1YSZ粉末的浆料在相同的固体含量下具有较低的粘度。悬浮液的固化深度适合于以50μm的层厚度，良好的层间连接和表面光洁度打印物体。没有观察到陶瓷中的关键缺陷，例如裂纹或分层。两种陶瓷的维氏显微硬度值均为11 GPa，并且在900°C时具有高达0.2 S /μm的高离子电导率，这表明DLP是一种有前途的方法，可以制造scan稳定的氧化锆零件作为SOFC应用的电解质材料。
