Abstract In recent times, the usage of polymers has experienced notable growth across diverse manufacturing sectors. Polymeric gears, integral to automation, material handling systems, toys, and household appliances, have become ubiquitous.

Lattice and Triply-Periodic-Minimal-Surface (TPMS) structures are widely employed in different engineering disciplines, combining interesting designs with optimal mechanical properties thanks to the capabilities of Additive Manufacturing. In this framework, a technique based on filling 3D-printed flexible structure shear-thickening fluid (STF) is proposed improve response resulting bi-phase composite under impact loads low-velocity regime up around 3 m/s. Test data indicate that once critical shear rate threshold for reached, STF-filled can effectively smooth peak acceleration by 50%, decrease penetration depth significantly enhance energy absorption capability remarkable 85%. The hybrid paves way novel functional applications, exploiting adaptive behavior non-Newtonian fillers. To end, Finite-Element model further investigate optimize underlying fluid-structure interaction responsible improvement dynamic compressive response.
