Problems solved by technology

[0005] At present, the products printed by 3D printers are mostly colorless or single-color 3D entities due to the limitation of the performance of the molding materials themselves. Such 3D models cannot attract people's attention due to their monotonous and dull colors. Therefore, such 3D printing Gradually unable to meet the increasing individual needs
However, in the current 3D printers that can print colored entities, it is necessary to provide a variety of molding materials of different colors, resulting in a rather complicated overall structure and high manufacturing costs. At the same time, it is limited by the molding material itself, so it is difficult to achieve high-precision printing of 3D solids with rich colors

Abstract

The invention discloses a color three-dimensional printing molding material and a preparation method thereof. The molding material comprises the following components in parts by weight: 80-90 parts of plastic raw materials, 0.45-3 parts of diffusion oil, 0.5-1.5 parts of coupling agent and 4-10 parts of photochromic materials. The preparation method comprises the following steps: (1), dispersing and mixing 80-90 parts by weight of plastic raw materials with 0.45-3 parts by weight of diffusion oil to obtain a fist material mixture; (2), mixing 0.5-1.5 parts by weight of coupling agent with 4-10 parts by weight of photochromic materials to obtain a second material mixture; (3), mixing and stirring the first material mixture with the second material mixture to obtain a third material mixture; and (4), extruding the third material mixture by virtue of a plastic extruding machine, and producing a wire-shaped molding material by virtue of wire drawing. According to the invention, the integral structure of the color three-dimensional printer can be simplified, the manufacturing cost can be lowered, and color three-dimensional solid printing with relatively high precision and rich color can be realized.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a molding material applied to a color three-dimensional printer, and also to a preparation method of the molding material. Background technique [0002] Three-dimensional printing, also known as 3D printing, belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using molding materials, and constructing objects by stacking and accumulating layer by layer (that is, "layer-by-layer modeling method") ). In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. [0003] The process of 3D printing is firstly modeled by computer-aided design (CAD) or computer animation modeling software, and then the built 3D model is "divided" into layer-by-layer sections, and then the processing path is obtained acc...
