Using a casting nanocomposite 5, here we create transparent fused silica glass components using stereolithography 3D printers at resolutions of a few tens of micrometres.
These drawbacks have made glasses inaccessible to modern manufacturing technologies such as three-dimensional printing (3D printing). However, glasses and especially high-purity glasses such as fused silica glass are notoriously difficult to shape, requiring high-temperature melting and casting processes for macroscopic objects or hazardous chemicals for microscopic features 3, 4.
Glass is one of the most important high-performance materials used for scientific research, in industry and in society, mainly owing to its unmatched optical transparency, outstanding mechanical, chemical and thermal resistance as well as its thermal and electrical insulating properties 1, 2, 3.
