利用光固化快速成型技术，可以制作出具有与传统工艺相似烧结性能的三维复杂陶瓷零件。高浓度可固化陶瓷系统（46. 64体积%已经开发了具有合适的流变行为和足够的UV反应性的粉末）。本文重点研究了影响UV反应性的两个关键参数，即固化深度和宽度，它们将控制尺寸分辨率和加工时间。在恒定的紫外激光照射（110 mJ·cm-2）条件下，研究了粉末浓度、粉末性质和平均粒径等因素对这两个关键参数的影响。激光曝光的效果和紫外光与反应体系的相互作用将在即将发表的论文中详细介绍。
Three-dimensional complex ceramic parts can be elaborated with sintered properties similar to those obtained by classical processing techniques, using stereolithography as rapid prototyping method. Highly concentrated curable ceramic systems (46...64 vol.% powder) with suitable rheological behaviour and adequate UV reactivity have been developed. This paper is focused on two critical parameters of the UV reactivity, i.e. cure depth and width, witch will control the dimensional resolution and the processing time. The influence of several factors as powder concentration, nature of powder and the mean particle size on these two critical parameters, was studied under a constant UV-laser exposing (110 mJ·cm -2 ). The effect of laser exposure and the interaction of UV light with the reactive system will be detailed in a forthcoming paper.
