Problems solved by technology

[0002] Color models can theoretically be printed and manufactured using color 3D printers, but color 3D printers are few and expensive in the market, and can only print limited colors
In addition, in terms of manufacturing time and cost, traditional color 3D printing is also time-consuming and expensive
In addition, in terms of the structural design of colored lampshades, most of the current methods are texture maps, and there are few studies on obtaining colored structural lampshades through structural design, and the traditionally designed structure can only be realized by color 3D printers
Therefore, the wide application of colored lampshades is limited.

Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0043] A method for designing and implementing a complex-structured colored lampshade suitable for 3D printing, which can be divided into several main steps: designing the porous shell structure inside the lampshade, constructing the lampshade, printing the base structure of the lampshade, and pouring the colored solution:

[0044] (1) Porous shell structure design inside the lampshade

[0045] Taking the G surface as an example, there are many

[0046] Porous shell structure, first construct multi-scale three-period minimal surface:

[0047]

[0048] Among them, r is a three-dimensional vector, X=2tπx, Y=2tπy, Z=2tπz, x, y, z are the corresponding coordinates, and t is the period control parameter (the value interval is [0.5,2]).

[0049] Next, the porous shell structure of two color spaces is constru...

Abstract

The invention belongs to the technical field of computer-aided design and industrial design and manufacturing, and relates to a method for designing and realizing a color lampshade with complex structure suitable for 3D printing. Firstly, the representation of porous shell structure based on three-period minimal curved surface and the design method of corresponding porous shell structure are presented. Then, a color lampshade model with adjustable space and structure is designed, and the base junction of the lampshade is printed by 3D printer. At last, that base structure of the lampshade is poured by the color solution, and a variety of complex color lampshades are obtained. The porous shell-like structure obtained by the invention has the characteristics of smoothness, full connectivityof partition space and the like, and the type of the porous shell-like structure and the void ratio are simple and adjustable. Compared with full-color 3D printing technology, this method has the advantages of controllable color space classification, less printing time and lower manufacturing ratio.
