Building Sequence of Boundary Model in Layered Manufacturing

Even though building functional metal parts directly from CAD files has been the focus of many researches for many years, parts made by Layered Manufacturing (LM) have limited surface accuracy and long build time due to the sacrificial support structures. The Multi-Axis Laser Aided Manufacturing Process (LAMP) system improves build time by adding two more rotation axes to the system in order to reduce the support structures. The strategy to decompose the part model to sub-volumes or cells and the algorithm to arrange the deposition of those cells are discussed. The problems and questions of how much material should be deposited along the determined directions are also addressed in this paper.
