3D printer for multicolor stacking printing

Abstract

The invention discloses a 3D printer for multicolor stacking printing. The 3D printer comprises a support main body, a feeding control device and a rotary main body. The feeding control device is arranged at the upper end of the support main body and is used for controlling the flowing direction of raw materials. The rotary main body is arranged at the lower end of the support main body and can rotate around the axis of the rotary main body. A plurality of extrusion heads are arranged at the lower end of the rotary main body and are arranged evenly at intervals in the peripheral direction of the rotary main body. The feeding control device comprises a frame provided with a feeding hole for guiding solid raw materials. The upper end of the support main body is provided with a guide groove used for guiding the frame to move in the horizontal direction. The support main body is provided with single-color melting channels and color mixing feeding channels which are located in the guide groove and are in spacing alternative distribution in the guide direction of the guide groove. The frame is connected to a guide switching mechanism, through power output by the guide switching mechanism, the feeding control device can move in the guide direction of the guide groove, and switching is achieved between a color crossing guide state and a color mixing guide state.

Description

[0001] This invention is a divisional application for an invention patent with an application date of August 28, 2017, an application number of 2016103542006, and an invention title of "integrated color 3D printer with cross-color and color-mixing". technical field [0002] The invention relates to a 3D printer, in particular to a color 3D printer. Background technique [0003] 3D printing has brought about a global manufacturing revolution. In the past, component design was completely dependent on whether the production process could be realized. The emergence of 3D printers will subvert this production idea, which makes enterprises no longer consider production when producing components. Process issues, the design of any complex shape can be realized by 3D printer; 3D printing can directly generate objects of any shape from computer graphics data without machining or molds, thus greatly shortening the production cycle of products and improving production efficiency. produc...

Problems solved by technology

[0004] Existing 3D printers mostly use monochrome printing, and color printers mostly use mixed-color raw materials for printing, that is, mixed materials produced by mixing raw materials of various colors; 3D printers currently on the market do not use cross-color raw materials for printing , the cross-color raw material is made of multiple sections of different-color raw materials connected in series. Since different printing objects require different cross-color lengths and color distribution schemes, it is impossible to make cross-color raw materials before printing. Therefore, constraints The realization of cross-color printing
