Hello, I'm currently working on a university project which is investigating the use of topology optimisation for additive manufacturing (AM). One of the side effects of some AM processes is that built components will exhibit different mechanical properties along each axis. This is dependent upon orientation of the design within the AM build chamber. In respect to Selective Laser Melting or Electron Beam Melting in Titanium-64, could anybody recommend an approach (within Optistruct) which could account for the varying mechanical properties? Alternatively, if anybody knows of a way to heat treat AM parts so that the anisotropy/orthotropy is negated during optimisation, that too would be helpful. Any help with this issue would be hugely appreciated! Thanks, Dan Walton
