Abstract Lightweight thin-walled structures with lattice infill are widely desired in satellite for their high stiffness-to-weight
ratio and superior buckling strength resulting from the sandwich effect. Such structures can be fabricated by metallic
additive manufacturing technique, such as selective laser melting (SLM). However, the maximum dimensions of
actual structures are usually in a sub-meter scale, which results in restrictions on their appliance in aerospace
and other fields. In this work, a meter-scale thin-walled structure with lattice infill is designed for the fuel tank
supporting component of the satellite by integrating a self-supporting lattice into the thickness optimization of the
thin-wall. The… More >
