Sample Text	This article introduces a novel method to enhance the damping performance of triply periodic minimal surface (TPMS) structures by integrating metamaterials with constrained layer damping (CLD) applications. This objective is accomplished by combining a viscoelastic silicone polymer layer with a primitive TPMS structure fabricated through laser powder bed fusion using aluminum alloy powder. Finite-element method (FEM) models using voxel elements, due to their high accuracy and computational efficiency, are developed to analyze the damping behavior of the TPMS-based CLD structure across various frequencies. Experimental modal test results validate the FEM model with high accuracy. Two distinct damping characterization methods, both time-domain and frequency-based, are employed to quantify the damping performance. The results reveal a fivefold improvement in damping performance in the time domain compared to the metal TPMS structure. In the frequency domain, the structure demonstrates 76% lower cumulative vibration compared to the metallic reference using the integral of frequency response method.
