Higher precision in additive manufacturing has enabled engineers to fabricate materials with exotic and extreme mechanical characteristics. Topology optimization is an effective tool in designing microstructures tailored for target macro scale properties. In this work, we consider designing functionally graded microstructure using topology optimization with embedded manufacturability. Homogenization is used to represent the properties of the graded material in the topology optimization algorithm, uniaxial and biaxial material gradations are studied. Also, manufacturability (overhang constraints, etc.) of the microstructures is implemented in the formulation to circumvent design features that may be the likely causes of failure during fabrication using 3D printing technologies. Functionally graded materials from topology optimization provide a greater variety of design options that may enhance the performance and efficiency of the resulting structures.
