Cross-color and mixed-material printing method of color 3D printer

Abstract

The invention discloses a cross color and mixing printing method of a color 3D printer. The method comprises the steps that a rotating body is rotated, and extrusion heads communicated with runners are adjusted; due to the fact that the rotating body is arranged on the lower bottom face of a supporting body and can rotate around the axis of the rotating body, the lower bottom face of the rotatingbody is provided with a plurality of extrusion heads arranged in an evenly spaced manner in the circumferential direction, connectors in one-to-one correspondence communication with the extrusion heads are formed in the contact end face of the rotating body and the supporting body, wherein the number of the connectors is the same with that of the extrusion heads, and one connector is communicatedwith one of the runners; each extrusion head can only extrude same raw materials of the single color, through rotation of the rotating body, cross color printing can be achieved; a color mixing runnercommunicated with a single-color runner is formed in the supporting body, the feeding end of the color mixing runner is connected with a mixing mechanism, when the extrusion heads in the vertical state are communicated with the color mixing runner through the single-color runner, mixing materials can be extruded.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a color 3D printer. Background technique [0002] 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. productivity. Although it still needs to be perfected, the market potential of 3D printing technology is huge, and it is bound to become one of the many breakthrough technologies in the future manufacturing industry.

Problems solved by technology

[0003] 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
