Additive manufacturing of silica glass by stereolithography is a new technology. Improving the efficiency of this technology is an important issue. In this work, a stereolithography system using top-down approach and a compatible suspension for this approach was developed. The debinding behavior of the green part (the solidified suspension) was discussed in detail based on the results of thermogravimetric analysis and Fourier transform infrared absorption spectroscopy. A fast heat treatment within 16 hours was adopted for debinding and sintering of the green part which took only 1/3 of the time of previous report. Designed glassware which could not be processed by conventional technologies was manufactured in this way, and the products showed similar properties with fused silica, as confirmed by X-ray diffraction and UV-vis-IR spectrometer.
通过立体光刻法进行石英玻璃的增材制造是一项新技术。提高该技术的效率是一个重要问题。在这项工作中，开发了一种采用自上而下方法的立体光刻系统以及适用于该方法的兼容悬浮液。基于热重分析和傅里叶变换红外吸收光谱的结果，详细讨论了生坯部件（固化悬浮液）的脱脂行为。对生坯部件采用了16小时内的快速热处理进行脱脂和烧结，这仅占先前报道时间的1/3。通过这种方式制造出了传统技术无法加工的设计玻璃器皿，并且经X射线衍射和紫外 - 可见 - 红外光谱仪证实，产品具有与熔融石英相似的性能。
