Abstract: The present invention relates to a paper-based 3D printing device and a printing method. The paper-based 3D printing device comprises a printing platform, a three-axis linkage platform, a cutting head and an inkjet head. The printing platform is used for placing paper, and the three-axis linkage platform is arranged to, firstly, drive the cutting head to cut the corresponding paper along the contour of a preset model to form a cutting seam, and then drive the inkjet head to inkjet color toward the cutting seam along the contour of the preset model. The paper-based 3D printing device and the printing method save ink, and can directly spray the ink at the cutting seam, which is equivalent to coloring the outer surface of the model, effectively improving the coloring effect, making the coloring of the outer surface of the model uniform, eliminating the step of printing one by one.
