The digital fabrication of oxide glasses by three-dimensional (3D) printing represents a major paradigm shift in the way glasses are designed and manufactured, opening opportunities to explore functionalities inaccessible by current technologies. The few enticing examples of 3D printed glasses are limited in their chemical compositions and suffer from the low resolution achievable with particle-based or molten glass technologies. Here, we report a digital light-processing 3D printing platform that exploits the photopolymerization-induced phase separation of hybrid resins to create glass parts with complex shapes, high spatial resolutions and multi-oxide chemical compositions. Analogously to conventional porous glass fabrication methods, we exploit phase separation phenomena to fabricate complex glass parts displaying light-controlled multiscale porosity and dense multicomponent transparent glasses with arbitrary geometry using a desktop printer. Because most functional properties of glasses emerge from their transparency and multicomponent nature, this 3D printing platform may be useful for distinct technologies, sciences and arts.

使用相分离树脂对多组分玻璃进行三维印刷。

通过三维（3D）打印对氧化物玻璃进行数字制造代表了玻璃设计和制造方式的重大转变，这为探索当前技术无法实现的功能提供了机会。3D打印玻璃的一些诱人示例在化学成分上受到限制，并且受基于粒子的玻璃或熔融玻璃技术所能达到的低分辨率的困扰。在这里，我们报告了一个数字光处理3D打印平台，该平台利用了光致聚合引起的杂化树脂的相分离，以创建具有复杂形状，高空间分辨率和多氧化物化学成分的玻璃部件。与传统的多孔玻璃制造方法类似，我们利用相分离现象来制造复杂的玻璃零件，并使用台式打印机制造出具有任意几何形状的光控多尺度孔隙度和致密的多组分透明玻璃。由于眼镜的大多数功能特性都来自于其透明度和多组分性质，因此该3D打印平台可能对独特的技术，科学和艺术有用。
