Vulcanized and devulcanized ground tire rubber microparticles have been used as a minor phase in acrylonitrile butadiene styrene copolymer (ABS) and thermoplastic polyolefins (TPO) for the development of materials with desired functionalities by 3D printing. These polymers have been selected because they () present part of the plastic waste generated by the automotive industry and () have totally different properties (ABS for its stiffness and robustness and TPO for its softness and ductility). The study aims to improve the circular economy of the automotive industry by proposing a promising route for recycling the generated tire rubber waste. In this respect, emergent technology for plastic processing such as 3D printing is used, as part of the additive manufacturing technologies for the prolongated end of life of recycled plastics originated from automotive waste such as ABS and TPO. The obtained results revealed that () the composites are suitable for successful filament production with desired composition and diameter required for successful 3D printing by fused deposition modeling, and that () the optimization of the composition of the blends allows the production of materials with interesting mechanical performances. Indeed, some of the investigated ABS-recycled rubber tire blends exhibit high impact properties as TPO-based composites do, which in addition exhibits elongation at break higher than 500% and good compression properties, accompanied with good shape recovery ratio after compression.
硫化和再硫化的地面轮胎橡胶微粒已被用作丙烯腈丁二烯苯乙烯共聚物（ABS）和热塑性聚烯烃（TPO）中的次要相，以通过3D打印开发具有所需功能的材料。选择这些聚合物是因为它们（）是汽车工业产生的部分塑料废料，并且（）具有完全不同的性能（ABS具有刚度和坚固性，TPO具有柔软性和延展性）。该研究旨在通过提出一种回收产生的轮胎橡胶废料的可行途径，来改善汽车工业的循环经济。在这方面，使用了诸如3D打印之类的塑料加工新兴技术，作为增材制造技术的一部分，以延长源自汽车废料（如ABS和TPO）的再生塑料的使用寿命。所得结果表明，（）这些复合材料适合通过熔融沉积建模成功生产具有成功进行3D打印所需的组成和直径的长丝，并且（）共混物组成的优化允许生产具有有趣机械性能的材料。实际上，一些研究的ABS-回收橡胶轮胎共混物表现出与TPO基复合材料一样高的冲击性能，此外，其断裂伸长率高于500%，具有良好的压缩性能，压缩后具有良好的形状恢复率。
