This study explores the impact of metallic shells by electroforming method on mechanical behavior thermoplastic polyurethane (TPU)-based lattice structures. First, TPU structures were printed additive manufacturing technique. Then layers Ni and Cu as a thin shell dressed in baths solutions. Finally, uniaxial compression tests achieved samples. Results demonstrated substantial enhancements performance attributable to these coatings. Notably, Ni-coated structure (Ni-LS) exhibited peak yield strength 4.55 MPa, marking 1.08-fold improvement over Ni-Cu-LS 1.35-fold increase relative Ni-Cu-Ni-LS variant. Furthermore, energy absorption density coated was elevated nearly sixfold compared uncoated lattice, with multi-layer coatings providing additional gains. These results underscore potential Cu-coated lattices deliver exceptional strength-to-weight ratios enhanced capabilities.
