Provided is a method for exposure/development machining of 3D glass, comprising: first, spray-coating a colored photosensitive ink onto the entire concave surface of a 3D glass; then, feeding a profiled 3D photomask along with the 3D glass into a device equipped with parallel light, and performing exposure; before exposure, accurately positioning the 3D photomask with the 3D glass; during exposure, the two being tightly fitted together for exposure; the position on the 3D photomask corresponding to a target blank pattern being designed to be opaque; the structure of the ink at the light-transmissive position changing after exposure; after developing in a developer liquid, the photosensitive ink on the target blank pattern being developed; the structure of the ink at the light-transmissive position being stable in the developer liquid, and a surface blank pattern being obtained. The method for processing the surface blank pattern of the 3D glass being changed from screen printing to a means using "spray-coatin
