We developed a series of photo-curable liquid resins containing silsesquioxane or silsesquioxane-structured molecules, which were subsequently utilized in a two-photon polymerization printing strategy. The printed structures underwent a controlled thermal treatment, converting them into inorganic glass while maintaining a temperature below the glass transition temperature of silica. Our investigation focused on elucidating the influence of the molecular composition of the resin on its intrinsic properties, print quality, and dimensional changes during the thermal conversion process. Our results underscore the capability of this approach to fabricate micro-optics with exceptional precision and complexity, thereby showcasing its potential for advancing micro-optical device fabrication.
