Abstract

The invention relates to photocuring ceramic 3D printing equipment and method. A controller is used for controlling an irradiating area of an ultraviolet light source; geometric shapes of components are set on a computer; a photocuring area is controlled; a scraper module is cooperatively used for layer-by-layer printing to continuously print out Si-(M)-N composite ceramic components; and the printed Si-(M)-N composite ceramic components are degreased, aged and sintered to finally obtain ceramic components. Compared with the prior art, the forming and continuous printing problems of Si-(M)-N composite ceramic on substrates are realized.

Description

technical field [0001] The present invention relates to the technical field of printing Si-(M)-N composite phase ceramics, in particular to equipment and methods for photocuring 3D printing of Si-(M)-N composite phase ceramic components. Background technique [0002] Light-curing molding technology is a kind of ceramic 3D printing technology. Light-curing ceramic 3D printing technology is an advanced ceramic preparation method for low-temperature 3D printing. It can form complex geometric shapes on substrates and can be used to manufacture high-performance ceramics-metals Composite complex components. However, the current photo-curable ceramic printing technology cannot enable Si-(M)-N composite ceramics to be effectively shaped and continuously printed on the substrate. Contents of the invention [0003] The object of the present invention is to provide a light-cured ceramic 3D printing device and method in order to overcome the above-mentioned defects in the prior art. ...
