Disclosed are a 3D printing method, and a decorative panel and a light box made by the method. The 3D printing method includes: printing a sheet material having a convex-concave surface with an ink that is curable by ultraviolet rays or electronic beams, making the printed surface keep the convex-concave shape and appearance of the sheet material surface, wherein the relationship of the printing resolution to the convex-concave density is 5 to 20 times so as to produce a decorative panel having 3D depth of field effects visually speaking. The decorative panel produced by the above-mentioned method can have an added printing ink protection layer on the printed layer surface thereof. A light box having the aforementioned decorative panel further comprises a back light source, the light source is a downward or lateral light-emitting diode or organic light-emitting diode. When the sheet material having a convex-concave surface is a transparent lens, it is possible to combine with a reflective sheet material or a back light source, forming a high contrast decorative panel or light box. |
