A 3D printed decorative film includes a transparent substrate with one-sided or two-sided concave or convex structures and a printing layer. The transparent substrate is a thermoplastic film. The heat softening temperature of concave or convex structures is at least 50 °C higher than that of thermoplastic film. An additional reflective layer was applied on top or bottom of printed layer. The reflective layer can be reflective powder, metalized film or high reflective index materials. The concave or convex structure lens is prism, half sphere, half cylindrical, pyramidal, Fresnel lens structures or the combination of above. |
