Additive manufacturing has had an exponential growth in recent years. This generates interest in its implementation for the construction of meta-structures. In this work, a one-dimensional computational model of a thin-walled straight beam is introduced, with the inclusion of mechanical mass-spring resonators. A 1D finite element model was built from the weak formulation of the virtual work principle. The model was evaluated through different dynamic tests, on straight beams manufactured with 3D printing technology. In this sense, the spring of the resonators was also manufactured with this technology. As a previous step, tests were carried out to determine the stiffness and effective mass parameters of the resonator, in order to obtain values for later comparison with the model to be evaluated. These parameters can generate a modification in the attenuation band, which makes the study of variability due to uncertainty in these parameters relevant to our analysis.
