The present invention relates to a method for forming three-dimensional (3D) patterns and products obtained thereby, especially to a method for forming three-dimensional patterns and products obtained thereby in which ink is coated on surface of a transparent substrate by an inkjet printer to form at least one layer of inkjet-printed pattern on the surface of the transparent substrate. Moreover, the transparent substrate is also sprayed with a reflective bottom layer covered over the inkjet-printed pattern. Thereby the inkjet-printed pattern is formed on the transparent substrate by the inkjet printer quickly and easily. A shiny and beautiful 3D effect is generated by the inkjet-printed pattern with a certain thickness and reflection of the reflective bottom layer. Thereby consumers are attracted to purchase related products and the industry's competitiveness is enhanced.
