Abstract

The invention discloses a 3D-printing-based method for making a three-dimensional luminous character. The 3D-printing-based method for making the three-dimensional luminous character comprises the steps that (1) a character-shaped face plate is engraved; (2) surrounding edge materials of the luminous character are deposited along the edge of the face plate through a three-dimensional printing device so as to obtain a surrounding edge; (3) the periphery of the surrounding edge is milled; (4) a bottom plate is engraved, a character-shaped fixing groove is engraved in the bottom plate, LED particles are distributed on the bottom plate, the bottom plate provided with the LED particles is arranged on the surrounding edge machined in the step (3), and machining of the whole three-dimensional luminous character is finished. According to the 3D-printing-based method, a high automation degree is achieved, machining of the surface plate and processes of the surrounding edge of the three-dimensional luminous character are combined by creatively adopting 3D printing and engraving technologies, and therefore machining and fixing procedures of the surface plate and the surrounding edge are automated. A character bending machine is omitted, a great deal of manpower consumed in the fixing procedures of the surface plate and the surrounding edge is also avoided, and the machining speed is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of making luminous characters, and in particular relates to a method and device for making three-dimensional luminous characters based on 3D printing. Background technique [0002] Three-dimensional luminous characters (advertising signs) are more and more widely used, which has played a very good advertising effect. The structure of a typical three-dimensional luminous character is composed of a panel, a border, a base, and LEDs. The LED particles are installed on the base, and the light emitted is emitted from the transparent panel, which has a strong visual appeal. The surrounding edge is mainly used to form a closed cavity with the panel and the base to protect the LED particles from external rainwater and the like. [0003] The typical method of three-dimensional luminous characters is to first cut the panel and the base, bend the plastic strip or stainless steel strip into the shape of the character t...
