    摘要: A method for printing colored 3D object adopted by a 3D printer (1) comprising a 2D nozzle (4) and a printing platform (4) is disclosed. The method comprises following steps of: reading coordinate information and color information of a colored model (5) of a 3D file if the 3D file is inputted; performing a slicing process according to the coordinate information and the color information for respectively generating a route file (6) and an image file (7) for each of a plurality of printing layers when the 3D file is inputted, wherein each route file (6) records a printing route of one printing layer, each image file (7) records color information of one printing layer; providing a boundary mark (22) on the printing platform (2); accepting a paper setting upon the printing platform (2), wherein the set paper is aligned with the boundary mark (22); and, controlling the 2D nozzle (4) to move and perform a 2D printing action for printing words or image contents on the paper.

    摘要: A three-dimensional printing method for a three-dimensional printer(100) is provided. The three-dimensional printer (100) includes a model printing head (131) and a color printing head (132) arranged along an X-axis and co-constructed, wherein the model printing head (131) prints a forming layer (200) on an X-Y plane of a platform (120) of the three-dimensional printer, and the color printing head (132) colors a coloring zone of the forming layer (200) along a Y-axis. The three-dimensional printing method includes: providing information of the coloring zone of the forming layer (200); determining the number of colorings of the color printing head (132) according to the information of the coloring zone by a processor; and driving the model printing head (131) by the processor to print the forming material outside a region of the forming layer (200).

    摘要: A three-dimensional printing method for a three-dimensional printer (100) is provided. The three-dimensional printer(100) includes a model printing head (131), a color printing head (132), and a platform (120). The model printing head (131) prints a forming layer (200) on an X-Y plane of the platform (120). The model printing head (131) and the color printing head (132) are arranged along an X-axis and co-constructed. The three-dimensional printing method includes:providing information of the forming layer (200) and a coloring zone thereof;driving the model printing head (131) by a processor to print the forming layer (200) and at least one material barrier (300) outside the forming layer (200);and after printing the forming layer (200) and the material barrier (300), driving the color printing head (132) by the processor to color the coloring zone along a Y-axis, such that the material barrier (300) is located on a moving path of the model printing head (131) during the coloring.
