Temperature Distribution Design Based on Variable Lattice Density Optimization and Metal Additive Manufacturing

Additive manufacturing (AM) is employed for fabricating industrial products with complex geometries. As topological optimization suitable designing geometries, studies have combined AM and optimization, evaluating the density of lattice structures as a variant optimization. The components fabricated via comprise voids. Models designed using should be modified to ensure AM. unit can easily fewer design modifications, this study uses an product. We propose method optimizing distribution controlling surface temperature uniformity products, such molds. effective thermal conductivity calculated homogenization finite element methods. changes depending on internal pore sizes. proposed methodology validated 3D example; minimization problem variations in target domain considered. variable embedded optimized, we experimentally performance cell optimal structure metal powder bed fusion
