中文摘要：
配制了一种具有光敏特性的陶瓷浆料，并用此浆料通过直写精细无模三维成型技术制备了线条直径为300μm的BaTiO3陶瓷基木堆结构．系统地讨论了光敏浆料的配制方法、浆料直写无模成型的工作原理以及采用的烧结工艺．制备过程中不同阶段的研究表明，光敏浆料中的BaTiO3纳米颗粒在烧结前未发生团聚，从而保证挤压成型顺利进行；烧结后样品成瓷效果好，各向收缩均匀，整体无变形、开裂．该技术具有成型速度快、制造周期短、可用材料范围广等特点．
英文摘要：
A novel kind of photosensitive ceramic inks was developed for Direct-Write Assembly and a BaTiO3 based woodpile structure with filament diameter of about 300μm was fabricated through this method. The preparation of the photosensitive inks, the principle of the Direct Ink Write （DIW） and the sintering schedule were investigated. The analyses at different states in the process show that the BaTiO3 particles keep monodisperse before sintering, which ensures a feasible extrusion of the ink. Moreover, the sintered products exhibit a fine ceramic forming result and isotropie contraction, with little deformation and few cracks. As a powerful molding technique, the DIW has merits of rapicl processing and good compatibility with various materials.
