Problems solved by technology

However, due to the difference in material properties between the printed material and the inkjet ink, the ink is easily peeled off from the printed material
At the same time, when printing and coloring three-dimensional objects layer by layer, due to the material characteristics of the ink, it is easy to cause insufficient bonding strength due to the existence of ink between different forming layers

Embodiment Construction

[0039] figure 1 It is a partial schematic diagram of a three-dimensional printing apparatus according to an embodiment of the present invention. figure 2 display figure 1 A partial schematic diagram of the printing assembly. Please also refer to Figure 1 to Figure 2 In this embodiment, the 3D printing apparatus 100 includes a frame 110, a platform 120, and a printing assembly 130. In addition, rectangular coordinates are provided to facilitate description. Here, the 3D printing device 100 is, for example, a fused deposition modeling (FDM) device, which can print the printing layer layer by layer on the platform 120 through the printing nozzle 131 of the printing assembly 130, and stack 3D objects layer by layer. . Furthermore, the printing assembly 130 further includes a coloring nozzle 132, which is, for example, an inkjet head, for coloring the surface of the printing layer or the three-dimensional object. In this embodiment, the colored nozzle 132 includes a plurality o...

Abstract

The invention provides a three-dimensional printing method adapted for a three-dimensional printing device to print a three-dimensional object, and the method includes: providing structure informationand coloring information of a three-dimensional object, performing a slicing process on the structure information of the three-dimensional object by a processor to obtain information of a plurality of printing layers, controlling the coloring information of the three-dimensional object to correspond to the information of the plurality of printing layers by the processor to obtain the informationof color layers corresponding to each of the printing layers, and disposing an adhesive layer on each of the printing layers and the color layer corresponding thereto, such that the adhesive layer covers at least a part of the color layer.

Description

Technical field [0001] The invention relates to a three-dimensional printing method. Background technique [0002] Three-dimensional printing is also known as additive manufacturing and additive manufacturing (AM). Its working principle is to layer raw materials under computer control to print three-dimensional objects with different shapes and geometric characteristics. Nowadays, a variety of three-dimensional printing technologies have been developed. Among them, Fused deposition modeling (FDM) is taken as an example. This technology is a method of heating and melting printing materials, and extruding the printing materials into filaments through the printing head. A printing layer is formed, and the printing layers are stacked layer by layer, and the printing material is cooled and solidified to form a desired three-dimensional object. [0003] Furthermore, there are often additional inkjet modules to color the aforementioned printed layer or three-dimensional objects. Of cour...
