Problems solved by technology

Among them, the traditional grinding process has a long cycle, low yield, and low material utilization rate, and cannot process complex-shaped optical elements such as diffractive aspheric surfaces; diamond single-point turning can process complex-shaped optical elements with high precision, but the material utilization rate is low. Low processing efficiency and high cost; precision molding is suitable for batch forming of optical components with complex shapes, but the cost of precision forming molds is too high, and the ability to meet product diversity is poor

Abstract

The invention discloses a 3D printing device used for chalcogenide glass components, relating to the technical field of chalcogenide glass preparation. The 3D printing device provides a stable preparation environment for chalcogenide glass, can achieve 3D printing of chalcogenide glass and has short production cycle and high production efficiency. The 3D printing device comprises a printing cavity, a control platform system, an atmosphere control system and a vacuum system, wherein a nozzle is arranged at the top end of the printing cavity and is used for spraying glass frit; the control platform system is arranged in the printing cavity; an operative surface of the control platform system is opposite to the nozzle and is used for bearing the glass frit sprayed by the nozzle; the atmosphere control system is communicated with the printing cavity and is used for providing protective gas for the inside of the printing cavity; the vacuum system is communicated with the printing cavity and is used for vacuumizing the inside of the printing cavity.

Description

technical field [0001] The invention relates to the technical field of chalcogenide glass preparation, in particular to a 3D printing device for chalcogenide glass components. Background technique [0002] Chalcogenide glass refers to the glass formed by the elements of group VIA of the periodic table of elements S, Se, and Te as the main elements and a certain amount of other elements introduced. Compared with oxide glass, chalcogenide glass has larger mass and weaker bond strength, and is an excellent infrared optical material with a spectral transmission range (0.9-15 μm). As an infrared optical material, chalcogenide glass has a wide transmission spectrum in the infrared band, stable photothermal characteristics, excellent chemical stability, continuously adjustable performance, and low preparation cost. are complementary. In the design of infrared optical components, the combination of chalcogenide glass with low thermal difference coefficient and crystal material wit...
