In additive manufacturing complex parts are built from thin layers of powder material. In the process called selective electron beam melting (SEBM), the powder is fused by the energy of an electron beam. The electron beam is guided by electromagnetic fields which allows a very fast deection, opening the way to various scan strategies. By using these scan strategies it is possible to control the resulting mesostructure in the material, which may range from a columnar to an equiaxed grain structure. With dierent grain structures, dierent macroscopic properties are expected. Long and oriented grains cause highly anisotropic behaviour and a uniform grain stucture will result in isotropic mechanical behaviour. In this contribution the macroscopic behaviour of additively manufactured Inconel 718 will be identified using a crystal plasticity model on the meso-level. The experimentally observed grain structures will be used to generate a representative volume element. Based on this RVE and computational homogenization, macroscopic mechanical param-eters will be identified and compared with experimental results.
