Color 3D printer

Abstract

The invention relates to a color 3D printer aiming to solve the technical problems that in the prior art, the requirement of a 3D printer for part cooperation is high, the 3D printer is damaged easily, and is inconvenient to maintain, when multi-color printing is carried out, colors of materials are mixed unevenly, and color 3D printing can not be completed. The color 3D printer comprises a sprayer and a printer body. The sprayer comprises a heating and mixing assembly and at least two feeding assemblies. The printer body comprises a rack, a tray installed on the rack, an X-axis moving mechanism and a Y-axis moving mechanism, wherein the X-axis moving mechanism and the Y-axis moving mechanism control the tray to move. The rack is further provided with a Z-axis moving mechanism for controlling the sprayer to move. The X-axis moving mechanism, the Y-axis moving mechanism and the Z-axis moving mechanism form a Cartesian coordinate system. The color 3D printer has the advantages that color 3D printing can be achieved without replacing the sprayer; all the parts are convenient to assemble and disassemble; three stepping motors are used for controlling silk conveying in three directions, locating is stable, and maintaining and replacing of the later period are convenient, and the whole process is high in automation degree.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a color 3D printer. Background technique [0002] 3D printers can automatically, directly, quickly and accurately transform design ideas into prototypes with certain functions or directly manufacture parts, thus providing a high-efficiency and low-cost implementation for parts prototype production and verification of new design ideas. means. That is, rapid prototyping technology is to use the data of three-dimensional CAD to accumulate layers of materials into solid prototypes through rapid prototyping machines. [0003] The 3D printers at the present stage often adopt the Cartesian coordinate system, and the movement of the printer nozzle is driven by three motors. For example, refer to the publication number CN104527066A, which is called a patented technology of a 3D printer based on a delta parallel mechanical structure. A 3D printer that uses multiple motors to control the...
