INTEGRATED DATA-DRIVEN DESIGN FRAMEWORK FOR ADDITIVE MANUFACTURING OF METALLIC MECHANICAL METAMATERIAL, D
Abstract
Metamaterials exhibit superior properties beyond the properties of conventional bulk materials due to their artificially designed structures. To achieve the unachievable performance with the base material, the internal structure of the metamaterial needs to be designed and fabricated on a scale of millimeters to nanometers. In this respect, the development of advanced additive manufacturing (AM) technologies, such as laser powder bed fusion (L-PBF), has facilitated metamaterial research with the capacity of tailoring geometrically complex structures. However, additively fabrication of the metamaterial structure with as designed geometry and property is not easily manageable due to the uncertainties in the process and the intrinsic geometrical imperfections induced by layer-by-layer fashion.
