Passive differential type feeding system of color crossing type color 3D printer

Abstract

The invention discloses a passive differential type feeding system of a color crossing type color 3D printer. The passive differential type feeding system is characterized by comprising a feeding power mechanism, wherein the feeding power mechanism comprises a power supply component, a differential component a, a differential component b and a linkage part, the differential component a can receive power provided by the power supply component, the linkage part is arranged between the differential component a and the differential component b, and the linkage part is used for receiving the power of the differential component a and transmitting the power to the differential component b. The passive differential type feeding system adopts a single driving mode, and can guide at most four strands of raw materials or consumables to move towards the interiors of runners; a power input component is used for providing the power, and when a first runner communicates with an interface and a second runner and a third runner are closed, accumulated pressures in the second runner and the third runner are increased and reverse resistance is generated on the solid raw materials, so that power wheel bodies used for guiding the raw materials into the second runner and the third runner stop rotating, and feeding is stopped.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printer capable of actively cross-coloring. 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.

AI Technical Summary

Problems solved by technology

[0003] Existing 3D printers mostly use monochrome for printing, and color printers mostly use mixed-color raw materials for printing, that is, mixed-color materials produced by mixing raw materials of various colors; currently, 3D printers 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
