Problems solved by technology

This method will have some problems in actual operation. For example, the method uses a three-dimensional printing device to deposit the surrounding material of the three-dimensional luminous characters along the edge of the panel, but the three-dimensional printing device cannot accurately find the edge of the panel and deposit the surrounding material along its edge; and the printing The resulting border has defects, which need to be milled, which not only increases the production cost, but also cannot be made into a transparent border, thereby limiting the style of the luminous characters; in addition, this method needs to engrave a fixing groove on the bottom plate, which is Not only need to increase the thickness of the bottom plate, but also further increase the time cost and raw material cost of making luminous characters

Embodiment 1

[0041] A 3D printing method for luminous characters, the preparation process is as follows:

[0042] ①. Drawing and modeling:

[0043] Design the size and shape of the luminous characters, make a wireframe graphic, import the graphic into ZWCAD, break the lines in the graphic into a large number of points, then connect the line segments and smooth them into circular arcs, and the broken points Connect them into continuous smooth lines (the accuracy of the tangent point is set to 0.01mm, and the arc tolerance value is set to 0.01~0.1mm), and the repair of the defect of the glyph wireframe is completed; the repaired wireframe is made into a wall thickness Word frame diagram, as a wireframe diagram for panel engraving and stored as a file in .dxf format, then open the file with Adobe illustrator software and convert it into a file in .eps format, and finally open the file with Wentai engraving software and convert it into a file in .ac6 format. Thus the NC machining path is derive...

Embodiment 2

[0054] The difference from Example 1 is:

[0055] The nozzle diameter of the 3D printer used in step ③ is 0.4mm, the wall thickness is 1.0mm, the layer thickness is 0.3mm, the temperature is 200°C, the hot bed is 40°C, and the printing speed is 40mm / min.

Embodiment 3

[0057] The difference from Example 1 is:

[0058] In step ③, the shape of the rib 31 on the light board 3 is designed as a hollow figure and printed, and the length of the finally obtained luminous characters is 400 mm.

Abstract

The invention aims to provide an efficient and energy-saving 3D printing method of luminous words. The 3D printing method of the luminous words includes the technical steps that 1, a drawing is designed and a model is made; 2, a luminous word panel is carved; 3, a vertical wall and a lamp panel are printed; 4, a light source is pasted; and 5, assembling is performed. The method has the beneficial effects of being high in printing precision and printing speed, easy to operate, nontoxic, dustfree, environment-friendly, efficient, capable of saving cost and the like. The obtained luminous words are easy to assemble and disassemble and convenient to maintain later, have flexible and varied patterns and styles and have a wider application range. The demands of various occasions can be met by matching colors of the words at will.

Description

technical field [0001] The invention relates to luminous characters commonly used in the field of advertising signs, and in particular provides a simple and efficient 3D printing method for luminous characters. Background technique [0002] Luminous characters are luminous fonts made of light-emitting diodes as light sources. They have many advantages such as beautiful in the daytime, bright in the night, energy saving, durable, and good publicity effects. They are widely used in the field of advertising. At present, the preparation of luminous characters is mainly based on the use of engraving machines, bending machines and other equipment combined with manual preparation. This method requires the cooperation of large-scale equipment, site space and technical proficiency to complete the production. Not only is the efficiency low, but it will also cause Raw material waste. [0003] With the advent of the national innovation boom, 3D printing technology has developed explosi...
