Abstract Scope |
Traditional additive manufacturing (AM), though it has revolutionized prototyping and small batch manufacturing, is geometrically limited to parts without overhangs or inclusion of supports at the sacrifice of surface quality. Wire-arc additive manufacturing (WAAM) and other 5-axis AM remove these limitations by rotating both the workpiece and the heat source, allowing for more complex geometries. However, rotating the heat source introduces new thermal variability as old material is reheated in varying directions rather than just downwards into the bed. The affects of these temperature cycles are not well known. This work focuses on finite element (FE) simulations of 5-axis material deposition processes for geometries with varying overhangs sliced multi-directionally. The relationship between cooling and heat source directions relative to deposited material will be explored, as well as the current limitations of FE simulations of 5-axis AM. |
