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).
