Color 3D (Three Dimensional) printer based on digitization micro jet process and shaping method based on color 3D printer

Abstract

The invention discloses a color 3D (Three Dimensional) printer based on a digitization micro jet process and a shaping method based on the color 3D printer. The color 3D printer comprises an operation platform, wherein an operation opening is arranged on the operation platform; a first moving mechanism which moves along the Y axis direction is arranged on the operation platform on the two sides of the operation opening; a second moving mechanism which moves along the X axis direction is arranged on the first moving mechanism; a nozzle group is arranged on the second moving mechanism; a UV (Ultraviolet) curing light is arranged on one side of the nozzle group; the nozzle group consists of a nozzle C, a nozzle M, a nozzle Y, a nozzle K and a supporting nozzle which are uniformly arrayed and are connected with one another; the nozzle group is connected with an ink supply group; a forming worktable is arranged under the operation platform; the forming worktable is connected with a third moving mechanism which moves along the Z axis direction and is arranged to be parallel to the first moving mechanism. The color 3D printer disclosed by the invention is small in size, relatively low in cost, low in operation cost and high in forming speed; the range of available materials is wide; and no pollution is generated during a forming process.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a color 3D printer and a molding method based on a digital micro-spraying process. Background technique [0002] At present, a variety of 3D printing equipment and methods are emerging, including stereolithography (SLA), selective laser sintering (SLS), layered solid manufacturing (LOM), fused deposition modeling (FDM), and three-dimensional printing. (3DP) etc. 3D printing with droplet jetting is currently the most viable technology in rapid prototyping and has broad application prospects. [0003] Stereolithography (SLA) and selective laser sintering (SLS) are common 3D molding methods used in industrial production. They have high molding precision but high equipment and material costs, complex structures, and high requirements for molding environments. They cannot print colored parts.

AI Technical Summary

Problems solved by technology

[0003] Stereolithography (SLA) and selective laser sintering (SLS) are common 3D molding methods used in industrial production. They have high molding precision but high equipment and material costs, complex structures, high requirements for molding environments, and color parts cannot be printed

Fused deposition modeling (FDM) is low cost, but also low efficiency, poor surface quality, poor stability, cannot print full color parts

Layered entity manufacturing (LOM) and three-dimensional printing molding (3DP) molding methods are high in cost and low in efficiency, the surface of the part is rough, and the dimensional accuracy is low. Printing colored parts is achieved by coloring the printing material, and the color cannot completely restore the true color of the part.
