 A hierarchical metamaterial manufactured through fused deposition modelling, FDM, is proposed in this work which exhibits simultaneous acoustic and mechanical energy absorbing capacities. The metamaterials absorption bandwidth increases with the growth of the hierarchical order with an ultra-broad half-absorption banned from 0.96 to 6.00 kHz for the fourth order. The unique resonant responses are demonstrated through analytical, numerical, and experimental analysis, revealing the enhancement mechanism through impedance matching and resonant damping states. Compared with its original counterpart, the specific energy absorption of the first order and second order hierarchical metamaterials increases by 228% and 434%, respectively, providing an effective approach for designing multifunctional metamaterials.
