北京化工大学和山东玲珑轮胎股份有限公司联合开发出3D打印165 70/R12聚氨酯轮胎,并对成品轮胎进行了测试,这是国内首次通过3D打印方式制备出标准规格轮胎(如图1所示)。该轮胎采用热塑性聚氨酯材料、通过熔融沉积法(FDM)完成3D打印,为免充气轮胎,内部为正六边形空心结构。在双方的前期研究中发现,由于聚氨酯材料具有低生热、高耐磨、抗撕裂等特性,因此具 Beijing University of Chemical Technology and Shandong Linglong Tire Co., Ltd. jointly developed 3D printed 165 70 / R12 polyurethane tires, and finished tires were tested, which is the first time in China by 3D printing methods to prepare a standard tire (Figure 1) . The tire uses thermoplastic polyurethane material, through the melt deposition method (FDM) to complete 3D printing, to avoid inflated tires, the interior is a hexagonal hollow structure. In both the preliminary study found that, due to polyurethane materials with low heat, wear resistance, tear and other characteristics, therefore
