Multi-color automatic material changing 3D printer

Abstract

The invention discloses a multi-color automatic material changing 3D printer, and relates to the field of 3D printing. The 3D printer comprises a bottom plate, a printing platform, a plurality of material discs, a plurality of printing devices, a Y-axis movement assembly, an X-axis movement assembly and a Z-axis movement assembly. Each material disc corresponds to one printing head, the taking head body and each printing head are configured to be of an automatic detachable connecting structure, the taking head body selects the corresponding printing head according to printing requirements, the corresponding printing head is automatically installed on the taking head body, and printing of different printing materials is completed. In other words, the materials of each color correspond to one independent printing head, only the specific printing head needs to be replaced for color changing each time, the head changing action is simple and convenient, redundant actions are not needed, nozzles do not need to be washed, printing and material changing towers do not need to be boiled, and the printing efficiency can be greatly improved. Meanwhile, due to the fact that each color material is provided with the corresponding printing head, the problem of color pollution does not exist, and the printing effect is better.

Description

technical field [0001] The present application relates to 3D printers, in particular to a multi-color automatic refill 3D printer. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technique of constructing objects by layer-by-layer printing using bondable materials such as powdered metal or plastic, based on digital model files. And multi-color printing is an inevitable direction for the development of 3D printers. [0003] Nowadays, most of the multi-color schemes of fuse-filament manufacturing 3D printers are multiple-in and one-out, that is, multiple color filaments enter the print nozzle from different channels together, and are ejected from one nozzle. [0004] The multi-color printing solution with one input and one output, because many materials are extruded through one nozzle, when changing materials of different colors, it is necessary to clean the nozzle, otherwise it will cau...
