Three-dimensional Ink jetting printing equipment and three-dimensional ink jetting printing method

Abstract

The invention relates to the field of three-dimensional printing and particularly relates to a three-dimensional ink jetting printing equipment and a three-dimensional ink jetting printing method. The three-dimensional ink jetting printing equipment comprises a control module, a movement module and a three-dimensional printing module, wherein the three-dimensional printing module is used for printing a thermoplastic material by layers according to data read by the control module; the movement module is used for controlling the movement of a printing object in a layered control process under the control of the control module; the three-dimensional ink jetting printing equipment further comprises an ink jetting module; the ink jetting module is connected with the control module and is used for carrying out ink jetting dyeing treatment on a current layer after an entity of the current layer is printed by the three-dimensional printing module; the movement module is used for controlling the movement of the printing object in an ink jetting process under the control of the control module; and the ink jetting module, the movement module and the three-dimensional printing module work independently under the control of the control module. According to the three-dimensional ink jetting printing equipment, a colorful plane printing technology can be applied to a complicated three-dimensional object and the printing cost is low.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to an inkjet 3D printing device and a printing method. Background technique [0002] At present, a variety of 3D printing equipment and methods are emerging, including laser stereolithography (LSF), three-dimensional printing technology (3DP), selective sintering (SLS), lamellar stacking molding (LOM), thermal Fusion deposition molding (FDM), stereolithography (SLA), etc. [0003] Among the various 3D printing methods, methods that can better realize full-color 3D printing include three-dimensional printing technology (3DP), stereolithography (SLA), etc., but the printing costs are relatively high; Although the printing cost of the stacking solidification molding method (FDM) is relatively low, it is difficult to achieve full-color 3D printing because the materials used for three-dimensional molding are difficult to mix and dye when ejected. In addition, although inkjet printing can ach...

Problems solved by technology

However, this patent has the following disadvantages: it is impossible to achieve light-colored spray dyeing by using colored solid materials for mixing

The 3 kinds of raw materials involved in color mixing all have a certain color, and only a darker color can be obtained after mixing, but a lighter color or even white cannot be obtained

Since the color ink is oily or water-based,
