3D printing technology, also known as Additive Manufacturing (AM), is revolutionizing the manufacturing industry by directly producing products based on technological advances such as the development of the internet, software, and computing power. Also, the range of applications has been expanded from personal desktop printers to countless industries, including electronics, automobile, medical, and aerospace. Abrasion resistance is a property that a material can resist damage from wear. Such materials are used in various fields such as tiers, bearing, brake pads, shoe outsole, etc., and it is necessary to develop high abrasion-resistant materials for industrial use. Conventionally, carbon black has been used as an abrasion-resistant reinforcing filler, and its surface treatment and dispersing agent mainly have been studied. It is possible to improve the dispersibility of filler in the polymer matrix through surface modification, however, it has limitations, so it is necessary to study the structural aspects of the filler. In this study, high abrasion resistant composite with electrically exfoliated graphite (EG) was fabricated, as a new material for applications of 3D printing. Carbon materials were introduced to thermoplastic polyester elastomer (TPE) via multi-extrusion processes. The composites filled with EG and surface modified EG showed improved abrasion resistance compared with neat polymer and carbon black composites. Since EG has a layered structure like graphene and has a high aspect ratio, it is more advantageous than carbon black. In addition, various types of EG/TPE composite specimens such as tires and insoles were printed through the fused deposition modeling process. We expect that the composites and 3D printing technology could be applied for customized personal sports and leisure products requiring abrasion resistance.
