Since the manufacturing method of the conventional three-dimensional marking component requires not only molding using a molding device, but also an injection molding device or a foam molding device which is cumbersome and costly to process, a filling material such as a foaming material is filled. Into the pocket, and since the filler is not viscous, it is also required to attach a primer to the bottom surface of the filler so that the finished product can be attached to other articles, and the attachment is attached. After the primer is applied, the steps of attaching the release paper, cutting and removing the edge material are required. In addition, in another embodiment of the method for fabricating the conventional three-dimensional display component, after molding the stereoscopic image, it is necessary to cut a foamed rubber into a shape of a recess and then attach it. Filling the cumbersome and time-consuming process in the cavity, and after the foaming glue is filled, the step of attaching the release paper, cutting and removing the edge material is also required. Therefore, the conventional method for manufacturing the three-dimensional display component has various disadvantages such as complicated process, troublesome time-consuming production, low production efficiency, and high cost.
