This study investigates the problem of impact protection, with an emphasis on enhancing energy absorption and dissipation through advanced design and manufacturing methods. Conventional materials exhibit limitations in their ability to combine high energy absorption, low weight, and durability under repeated loading. To address these challenges, this work utilizes auxetic materials, which are characterized by a negative Poisson’s ratio and exhibit an exceptional capacity for damping and dissipating imposed loads. Their geometric complexity necessitates the use of additive manufacturing (3D printing), which enables the fabrication of complex lattices with precision and flexibility not achievable through conventional methods. The developed models were subjected to impact load simulations and were compared against conventional materials. The results indicated the clear superiority of the auxetic structures, showing a reduction in developed stresses of approximately 2.5%, a significantly lower mass, up to 55% less, and an increased capacity for deformation without catastrophic failure. The more uniform load distribution enhanced damping efficiency and demonstrated the value of these structures in applications requiring high energy absorption and simultaneous mass reduction. Finally, confirmed that the combination of auxetic materials and additive manufacturing can lead to innovative solutions for impact protection, with a wide range of applications in industry, sports, and personal protective equipment.
