Silica: 3D Printed Optical Quality Silica and Silica–Titania Glasses from Sol–Gel Feedstocks (Adv. Mater. Technol. 6/2018)

In article 1700323, Rebecca Dylla-Spears and co-workers form optical quality silica and silica-titania glasses by three-dimensional (3D) printing silica inks formulated directly from molecular precursors, followed by heat treatment and polishing. This method demonstrates the potential of sol-gel chemistry for creating alternate glass compositions for optical 3D printing applications, which may lead to chemical and structural tuning of optical components.
