Abstract:

A sol, aq. soln.-based ink is presented for fabrication of 3D transparent silica glass objects with complex geometries, by a simple 3D printing process conducted at room temp. The ink combines a hybrid ceramic precursor that can undergo both photopolymn. reaction and a sol-gel process, both in a soln. form, without any particles. The printing is conducted by localized photopolymn. with the use of a low-cost 3D printer. Following printing, upon aging and densifying, the resulting objects convert from a gel to a xerogel and then to a fused silica. The printed objects, which are composed of fused silica, are transparent and have tunable d. and refractive indexes. [on SciFinder(R)]
