3D printing product coloring device and method applying same for coloring

Abstract

The invention provides a 3D printing product coloring device and a method applying the same for coloring, which relate to the technical field of 3D color printing, provide references for the accurate positioning of feature points on a model chartlet and a model by utilizing the principle that three points form a line of laser, and allow the operating personnel to complete accurate positioning easily. The generation of a 3D printing model chartlet by a computer is equivalent to the stripping and flattening of surface of a 3D model. The water coating transfer printing is mainly characterized by transferring a planar chartlet converted by the computer onto a 3D printing model reversely through water pressure and the property that a water coating film can extend and retract freely along with water surface. The 3D printing product coloring device and the method applying the same for coloring fully exerts the advantages of high image definition and low cost of traditional 2D printing as well as high precise equipment and low cost material of single color 3D printing, greatly improves precision and color definition of color 3D printing, greatly reduces total cost, substantially widens the application range after coloring, and removes the obstacle of monotonous vision for the 3D printing model to enter people's life fully.

Description

technical field [0001] The invention relates to the technical field of 3D color printing, in particular to a 3D printing product coloring device and a coloring method using the device. Background technique [0002] 3D color printing has become one of the most popular 3D printing technologies because it can not only print the shape of the model that people need, but also make the model have the corresponding surface color. However, there is a big gap between the color schemes of the two existing color printers and the color of the model data in terms of clarity and color reproduction. The details are as follows: [0003] Full-color powder printing is the earliest and most used full-color printing type. The coloring method is to spray the pigment on the white powder consumables to dye the white powder at the corresponding point on the surface of the model into the corresponding color. Since the ink printed on the powder will spread around, the color of the model surface is r...
