Layer deposition is the deposition of a single layer or many layers. Layer arrangement is an arrangement of layers. A design is an arrangement of layers. A part is an arrangement of layers. AM is an arrangement of layers. A design can be called an arrangement of layers because it does not work unless it is divided into many layers. These layers are arranged in the design as per the design. If a design is different, the arrangement of layers in the design is different. This is how different parts are made. However, if the orientation of a design changes, it changes how layers are arranged. Therefore, for a design, there will be a number of arrangements as per the orientation.
