Colored 3D (Three Dimensional) printing equipment using fused deposition modeling method

Abstract

The invention provides colored 3D (Three Dimensional) printing equipment using a fused deposition modeling method. The colored 3D printing equipment comprises three sets of feeding mechanisms for filamentary raw materials with red, yellow and blue base colors, a material mixing heater (4), a static / dynamic pipeline material mixer (5), a replaceable type printing nozzle (6), a three-dimensional motion molding platform (7) with a heating function and an equipment control system, wherein the feeding mechanisms are composed of a discharging scroll (1), a stepping type motor feeding machine (2) and a feeding guide pipe (3). The colored 3D printing equipment is characterized in that a three-primary-color principle is utilized, namely the red, yellow and blue colors are mixed according to a proper ratio to obtain nearly all colors in the natural world; thermoplastic raw material fused wires or powder with the red, yellow and blue colors can be heated and mixed according to different ratios to form different colored printing materials, and then the fused deposition modeling (FDM) method is used for carrying out 3D printing to obtain a colored product. The colored 3D printing equipment has the beneficial effects that the disadvantage that a current colored 3D printing equipment using the fused deposition modeling method only can be used for printing a single-color or double-color product is overcome; the post-period coloring and processing time of the product is shortened, the working efficiency is improved and a 3D printing application is enriched.

Description

technical field [0001] The invention belongs to the field of 3D printing technology, and relates to a principle of using the principle of three primary colors, that is, the principle that almost all colors in nature can be obtained by mixing the three colors of red, green and blue in an appropriate proportion, through the thermoplasticity of the three colors of red, green and blue After the raw material fuse or powder is heated and mixed in different proportions to form different color printing materials, the color products are 3D printed by using the fusion deposition molding method (FDM method). Background technique [0002] 3D printing production technology is a kind of rapid near-net shape additive manufacturing technology. Its principle is that the software decomposes the three-dimensional parts and components designed by the computer into several layers of plane slices, and prints them out through 3D printers to produce the required materials of different materials.
