The 5-axis layered manufacturing technology facilitates fabrication of a part with overhanging features without the use of supports, thereby making a direct-to-use part from the layered manufacturing technology a reality. In this paper a direct slicing procedure for a CAD model, a crucial process-planning task for the 5-axis laser aided DMD process is described. The neutral exchange format IGES is used as the slice format. The machine G and M codes for a CNC 5-axis laser aided DMD machine are generated from the slice format and the deposition process is simulated. Implemented examples are included to explain the slicing procedure.
