Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures (Adv. Funct. Mater. 82/2026)

Silica Glass 3D-printed complex silica glass micro- and nanostructures of unprecedented quality and accuracy are manufactured via a 3D-printing route that combines high-speed two-photon grayscale lithography with a custom high-sensitivity organic-inorganic pre-glass feedstock resist. By smoothly blending contours the technique overcomes layering artefacts without sacrificing throughput, substantially advancing precision glass fabrication at the smallest scales.
