In all Rapid Prototyping(RP) processes, computer-aided design(CAD) solid model is sliced into thin layers of uniform, but not necessarily constant, thickness in the building direction. Each cross-sectional layer is successively deposited and, at the same time, bonded onto the previous layer, the stacked layers form a physical part of the model. The objective of this study is to develop a method for obtaining necessary coordinates$(x,\;y,\;\theta_x,\;\theta_y)$ to position linear hotwire of the cutting system in three-dimensional space for the Variable Lamination Manufacturing process (VLM-S), which utilizes expandable polystyrene foam sheet as part material. In order to examine the applicability of the developed method to VLM-S, various three-dimensional shapes, such as a spanner, a patterned columm, and a pyramid were made using data obtained from the method.
