Abstract: It discloses a high-speed reciprocating color 3D printer; said printer includes a nozzle assembly that is horizontally movable in one direction, preferably an X-axis direction, and a workbench that is vertically movable in the Z-axis direction. A plurality of spray pipes are mounted on the nozzle assembly, wherein, the spray pipes contains a variety of liquid printing materials, including white matrix material and a variety of color materials. In a movement process, each spray pipe works separately. The white matrix material is used to print out the image firstly, especially the darker area of the image, and then the color of the image is printed through the color material, and the resulting image partially protrudes outward.
