Abstract











This
paper introduces a new manufacturing aware design approach which
exploits the possibilities of additive manufacturing processes to
generate arbitrary geometries and simultaneously adjust the grain
structure of the materials by choosing particular scan strategies. A
combined experimental-simulative approach is developed which
experimentally analyses the producible grain structures in the
selective electron beam process, computes macroscopic material
properties for these grain structures and employs these material
properties in an optimization procedure in which the topology of a
part and the orientation of the grains are optimized. In one example,
the stiffness of a designed part can be increased by 30% when the
grain orientation is taken into account.
