The article presents the development of a technique for producing transparent silica glass products using LCD-stereolithography using a photopolymer composite. It is shown that ultrasonic treatment of the composite makes it possible to destroy agglomerates of SiO2 nanoparticles and achieve a more uniform distribution of them in the organic matrix, significantly reducing the sintering temperature. Optimal printing and removal modes of the polymer matrix have also been determined. As a result of sintering at a temperature of 1175 °C, transparent monolithic silica glass samples with a density of 2,19 g/cm3 and a shrinkage of ~30 % were obtained. The light transmission investigation showed that the samples provide 83,5 % transmission in the visible region of the spectrum.
