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.

A thermal transfer light pen and a thermal transfer apparatus favorably perform thermal transfer even using light as a heat source to a thermal transfer sheet and performing thermal transfer to a transfer object with an uneven surface. A thermal transfer light pen includes a hollow pen body including a front end portion, a pressing body in the front end portion of the pen body and including a curved surface projecting toward a front end, a light guide including a first end and a second end, at least a portion of the light guide inside the pen body, and a light source connected to the first end of the light guide. The second end of the light guide is disposed in the front end portion of the pen body and faces the pressing body in the pen body. The pressing body is made of a material transparent to light emitted from the light source.
