Abstract

The invention relates to a preparation method of a chalcogenide glass element based on 3D printing technology. The preparation method comprises: wiredrawing basic chalcogenide glass consumables, winding the obtained filaments onto a reel of a 3D-printing machine, and performing laser sintering, layer-by-layer filament paving, and post-treatment to obtain the chalcogenide glass element with a required shape. In the preparation method, a die is not required, and the dimensional precision is controllable, so that the method is suitable for fast and low-cost manufacture of chalcogenide glass elements with miniature and complex shapes. Problems of glass material transportation and feeding, high-temperature melting, and moulding in the prior art of glass 3D-printing moulding are overcome, and 3D printing of a chalcogenide glass element can be efficiently completed.

Description

technical field [0001] The invention relates to a method for preparing a chalcogenide glass element, in particular to a method for preparing a chalcogenide glass element based on 3D printing technology. 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. It is a special glass material with excellent infrared transmission performance. It has a wide range of transmission spectrum in the infrared band, stable photothermal characteristics, excellent chemical stability, continuously adjustable performance, low preparation cost and easy processing, and it is compatible with single crystal Infrared crystal materials such as germanium have complementary advantages in some properties, and can be widely used in military (night vision gun sights, infrared shoulder-launched missiles, fighter night vision cruise, etc....
