In the conventional 3D printer head, when printing an output, it is possible to print and output the output with only one color per head as shown in FIG.

More specifically, the lower pigment outlet 2 from the material inlet formed in the upper portion of the printer head 1 is formed with one passage. Accordingly, in the case of printing an output, since only one color per head can be realized on the output, there is a problem in that when expressing a product formed by 3D printing, the expressiveness of the printed matter is low.

As a more specific example, when outputting a wood texture is to be outputted as shown in FIG. 2, the monochromatic expression method as described above is such that the color of the tree trunk portion (A) and the leaf (B) Or a method of rendering a variety of colors to overprint the printing process has complicatedly changed the quality of the output.
