Review on Non-pneumatic Tires Fabricated by Metamaterials with 3D-printer

In this article, a review has been made on the types of metamaterials and non-pneumatic tires. The results show that rolling resistance in pneumatic tires was between 4 and 5%, while less than 3% in non-pneumatic tires. As a result, non-pneumatic tires have lower fuel consumption and higher efficiency than pneumatic tires. Moreover, the maximum tension in the non-pneumatic tire produced by the three-dimensional method increased by 12%. However, the vertical stiffness improved by about 82%. The use of metamaterials in the shear layer, if the strain energy in the middle layer was 50% less other than layers, can control the shear bending characteristics. In addition, it has been shown that the high ability of additive manufacturing in the production of complex structures has made 3D printers producing for suitable this type of tire. In some cases, non-pneumatic tires with high-temperature tolerance for use in aerospace have also been taken.
