Ceramic components require very high energy consumption due to synthesis, shaping, and thermal treatment. However, this study suggests that combining the sol-gel process, replica technology, and stereolithography has the potential to produce highly complex geometries with energy savings in each process step. We fabricated light-frame honeycombs of AlO, BaCaZrTiO (BCZT), and BaTiO (BT) using 3D-printed templates with varying structural angles between -30° and 30° and investigated their mechanical and piezoelectric properties. The AlO honeycombs showed a maximum strength of approximately 6 MPa, while the BCZT and BaTiO honeycombs achieved a d above 180 pC/N. Additionally, the BCZT powder was prepared via a sol-gel process, and the impact of the calcination temperature on phase purity was analyzed. The results suggest that there is a large energy-saving potential for the synthesis of BCZT powder. Overall, this study provides valuable insights into the fabrication of complex ceramic structures with improved energy efficiency and enhancement of performance.
由于合成、成型和热处理，陶瓷部件需要非常高的能量消耗。然而，本研究表明，将溶胶-凝胶工艺、复制技术和立体光刻相结合，有可能在每个工艺步骤中节省能源，生产出高度复杂的几何形状。我们使用3D打印模板制造了AlO、BaCaZrTiO（BCZT）和BaTiO（BT）的轻框架蜂窝结构，模板的结构角度在-30°至30°之间变化，并研究了它们的力学和压电性能。AlO蜂窝结构的最大强度约为6MPa，而BCZT和BaTiO蜂窝结构的d值超过180pC/N。此外，通过溶胶-凝胶工艺制备了BCZT粉末，并分析了煅烧温度对相纯度的影响。结果表明，BCZT粉末的合成具有很大的节能潜力。总体而言，本研究为制造具有更高能源效率和性能提升的复杂陶瓷结构提供了有价值的见解。
