Abstract
Known methods of producing a three-dimensional glass object comprise the step of shaping of a glass fiber, wherein the glass fiber provided with a protective sheath is fed continuously to a heating source, the protective sheath is removed under the influence of heat, and the glass fiber is softened. In order to facilitate the production of filigree or optically distortion-free and transparent glass objects as much as possible, and also enable the adjustment of optical and mechanical properties with high spatial resolution, in one aspect the glass fiber has a protective sheath with a layer thickness in the range of 10 nm to 10 μm.
