Abstract: Provided is a method of thermoforming a molding material to have a bent portion and a flat portion extending from the bent portion. The method includes: placing the molding material on a bending mold, the bending mold having a curved surface; and forming the bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold.

Abstract: A printing pad includes a bottom surface extending in a plane defined in a first direction and a second direction intersecting the first direction. A first upper surface faces the bottom surface. A first side surface connects the bottom surface and the first upper surface. A second portion is disposed on the first portion and includes a second upper surface facing the first upper surface and a second side surface connecting the first upper surface and the second upper surface. A width of the second portion in the first direction increases from the first upper surface towards the second upper surface.
