From: One-photon three-dimensional printed fused silica glass with sub-micron features
a Illustration of OμSL configuration and its forming process; bottom left inset: schematic of the 3D miniature Hong Kong dioramas structure in printing; and optical & electron microscopic images of the 3D-printed fused silica glass miniature Hong Kong dioramas microstructure. b Chemical structures of the nanocomposite precursor. PEG-functionalized colloidal silica as the silica source, PEGDA and TET as the PEG-based bifunctional and trifunctional monomer, hydroquinone as the stabilizer, Irgacure TPO as the photoinitiator, and SOG and Sudan I as the photo-absorbers. c High-temperature stability demonstration of an OμSL 3D-printed transparent fused silica glass MLA at hundreds of degrees. d Optical & electron microscopic images of the 4 × 6 honeycomb structure with slender threads centrally suspended. e Plot of the finest resolution against the maximum printing speed of the 3D-printed transparent fused silica glass in our work, together with the data of other reported 3D-printed transparent fused silica glass for comparison11,12,16,18,19,20,21,22,23,31,32,33,34,35.
