Multi-nozzle free-switching color 3D printer

Abstract

The invention discloses a multi-nozzle free-switching color 3D printer comprising 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 mainbody. The rotary main body is arranged on the lower bottom face of the support main body obliquely, and the included angle between the center axis of the rotary main body and the vertical plane is delta. The extrusion heads arranged on the lower bottom face of the rotary main body are arranged obliquely. The intersection angle between the center axes of the extrusion heads and the center axis ofthe rotary main body is beta. The included angle delta is equal to the intersection angle beta. The planes where the center axes of the extrusion heads 250 and the center axis of the rotary main bodyare located are reference surfaces a. The included angle between adjacent reference surfaces is gamma. The angle of every time of rotation of the rotary main body is an integral multiple of the included angle gamma.

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
