摘要:

3D打印技术目前能够制造具有复杂结构和定制特性的物体。在这样的框架中,3D光学结构的生产仍然受到印刷结构的不良均匀性的限制,所述3D光学结构通常基于光学透明基质,任选地掺杂有活性分子化合物和纳米颗粒。打印结构的体积不均匀性和表面粗糙度都会对3D打印光学组件中的光传播产生负面影响。在这里,我们调查光聚合为基础的印刷过程中,激光共聚焦显微镜。我们开发的实验方法允许原位研究打印过程,具有微尺度空间分辨率和实时性。光聚合动力学的建模允许不同的聚合制度进行调查和合理化的过程变量的影响。此外,打印材料中限制光传播的因素的起源是合理的,其目的是设想有效的实验策略,以提高打印材料的光学性能。

英文摘要:

3D printing technologies are currently enabling the fabrication of objects with complex architectures and tailored properties. In such framework, the production of 3D optical structures, which are typically based on optical transparent matrices, optionally doped with active molecular compounds and nanoparticles, is still limited by the poor uniformity of the printed structures. Both bulk inhomogeneities and surface roughness of the printed structures can negatively affect the propagation of light in 3D printed optical components. Here we investigate photopolymerization-based printing processes by laser confocal microscopy. The experimental method we developed allows the printing process to be investigated in-situ, with microscale spatial resolution, and in real-time. The modelling of the photo-polymerization kinetics allows the different polymerization regimes to be investigated and the influence of process variables to be rationalized. In addition, the origin of the factors limiting light propagation in printed materials are rationalized, with the aim of envisaging effective experimental strategies to improve optical properties of printed materials.
