What is it about?
This study investigates how 3D-printed plastic structures made from PLA absorb impact energy under both slow and high-speed loading conditions. Different specimen sizes were manufactured using fused deposition modeling (FDM) and tested to evaluate their energy absorption performance. The results show that loading speed and specimen geometry significantly influence the amount of energy absorbed. All specimens performed better under high-speed impacts, while intermediate-sized geometries demonstrated the highest improvement in energy absorption. These findings provide practical guidance for designing lightweight, energy-absorbing components for protective engineering applications such as vehicles, aerospace structures, and safety systems.

Why is it important?
engineering fields. This research provides experimental evidence on how the geometry of 3D-printed PLA components affects their ability to absorb energy under different loading speeds. Unlike many previous studies that mainly focused on static mechanical properties, this work compares both quasi-static and dynamic impact conditions, offering valuable insights for engineers designing protective structures. The findings can support the development of safer, lighter, and more efficient components for automotive, aerospace, defense, and other impact-resistant applications.
Perspectives
This research reflects my interest in advancing the application of additive manufacturing in protective engineering. I believe that combining experimental testing with optimized structural design can significantly improve the energy absorption capability of lightweight 3D-printed components. The findings motivate me to continue exploring innovative geometries, material optimization, and manufacturing strategies that can bridge the gap between laboratory research and practical engineering applications. I hope this work serves as a foundation for future studies aimed at developing safer, more efficient, and sustainable impact-resistant structures.
