Abstract
Additive manufacturing techniques such as Selective Laser Melting (SLM) are highly suitable for producing lattice structures with complex unit cell designs. These structures can be designed and built in such a way that their properties match the needs for both medical and structural parts. This paper presents a novel local stress method for fatigue analysis of such SLM lattice structures. The fatigue performance of Ti6Al4V and CoCr structures produced by SLM is assessed with this method. In addition, life-prolonging post-SLM heat and surface treatments are studied. The resulting methods and treatments can be extended to other types of AM structures.
