Glass slurry, preparation method thereof and method for 3D printing of glass device

Abstract

The invention belongs to the technical field of glass device preparation, and particularly relates to glass slurry, a preparation method thereof and a method for 3D printing of a glass device. A high-temperature melting and casting process is adopted for preparing a macroscopic object through a traditional method, a chemical method is adopted for preparing a fine structure, the preparation processis dangerous, environmental pollution is large, energy consumption is high, and efficiency is low. The invention provides the glass slurry. The glass slurry comprises 600-1000 parts of silicon dioxide, 600-800 parts of acrylic resin, 1-13 parts of a light absorber, 1-15 parts of a photoinitiator, 1-15 parts of a polymerization inhibitor, 1-10 parts of glycerol, 1-18 parts of polyvinyl alcohol, 1-18 parts of a defoaming agent and 1-15 parts of a sintering aid. By adding the sintering aid, the problem that high-viscosity slurry affects the printing precision is avoided, and a high-precision micro-lens glass device is obtained; through reasonable preparation of the glass slurry and the oxygen inhibition polymerization printing process, cracking is effectively inhibited, and the yield is increased.

Description

technical field [0001] The application belongs to the technical field of glass device preparation, and in particular relates to a glass paste, a preparation method thereof and a method for 3D printing glass devices. Background technique [0002] Micro-stereolithography is a new type of microfabrication technology developed on the basis of the traditional 3D printing process—stereolithography (SL). Compared with the traditional SL process, it uses a smaller laser spot (several microns), the resin undergoes a photocuring reaction in a very small area. Surface projection micro-stereolithography has the outstanding advantages of high molding efficiency and low production cost. It has been considered as one of the promising microfabrication technologies at present. Microstereolithography has been used in many fields such as tissue engineering, biomedicine, metamaterials, micro-optical devices, and microelectromechanical systems (MEMS). [0003] Glass is one of the most importa...

AI Technical Summary

Problems solved by technology

However, glass, especially high-purity glass, such as fused silica glass, is difficult to form. The traditional method of preparing macroscopic objects uses high-temperature melting and casting processes, and chemical methods are used to prepare fine structures. The preparation process is dangerous, environmentally polluted, and energy consumption is high. , low efficiency, the application provides a glass paste and its preparation method and a method for 3D printing glass devices
