Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a color mixing full-color coloring device for 3D printer consumables based on entity color recognition. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. The working principle of a 3D printer is basically the same as that of an ordinary printer. It superimposes the "printing materials" layer by layer through computer control, and finally turns the blueprint on the computer into a real object. This technology is often used in mold making, industrial design and other fields to make models or for direct manufacturing of some products. There are currently a variety of 3D printing technologies, and commonly used technologies include 3D printing of adhesive materials, 3D printing of light-curing materials, and 3D printing of molten materials....

Problems solved by technology

[0003] However, most of the FDM printers on the market can only print with single-color consumables or alternately print with two-color consumables. There are also a small number of three-color mixed-color rapid prototyping systems, but they are relatively expensive and mainly rely on the DELTA-style 3D printing mechanical structure to achieve printing. Whether it is a Cartesian 3D printing system or a DELTA 3D printing system, and the mechanical structure is a fixed dead structure, it cannot be modified according to the functions required by the user. Most color rapid prototyping systems are The precise algorithm is used to control the PLA printing consumables of different colors to enter the extrusion system of the 3D printer for heating and melting, so as to realize color 3D printing.

However, this printing method requires a very sophisticated algorithm to support the improved complex 3D printing mechanical structure, and this type of color 3D printer is expensive, and it is easy to replace different color consumables in a short period of time. As a result, the mixed consumables are broken, resulting in uneven discharge, and due to the continuous mixing and melting of PLA printing consumables of different colors in the extrusion system, the consumables of various colors will have a certain degree of difference in chemical composition. , it will lead to blockage of the extrusion system, and it is more likely to cause problems such as uneven color mixing and aesthetics

[0004] In addition, there is also a color 3D printer with inkjet coloring principle on the market, but it also has some technical and cost problems. The requirements are relatively high, and the requirements for ink types are mainly nano-scale inks and bio-based inks, whose prices are relatively high, and at the same time, due to the chemical reaction caused by high temperature, there is still a certain impact on the ink itself

And for the selection of printing colors, if the user encounters the desired color, he can only rely on memory to make a later selection, and there will be a large deviation from the expected color, which will affect the final molding effect

Moreover, the mainstream printers on the market only have a fixed mechanical structure, do not have a modular concept design, and only have fixed functions. There is no matching of different modules to achieve different printing effect requirements. It is inconvenient to modify and it is difficult to meet the diversification needs of users. art print effect
