Now technologies related to 3D printing are strongly leading the industrial revolution in all fields. However, unavoidable basic technical problems of 3D printing have prevented from an ideal technology of manufacturing products with conventional characteristics. This serious problem must be caused by the layer structure of products used by additive process, and the insufficient mechanical strength of the molding materials specific to each type of 3D printer.
In this study, we strongly focused on develop innovative high strength resin-based composite materials reinforced with nanocarbon, i.e. C60, CNT and graphene. These nanocarbon show extraordinary mechanical, physical and chemical properties with each superior characteristics. It is worth noticing that the mechanical properties, such as a strength, elastic modulus, hardness and so on, can be investigated incommensurably high values compared with those of commercial materials. Furthermore, these kinds of nanocarbon have superior geometric and nanometer-scale dimension characteristics as reinforcement materials considering various 3D printing processes. We researched the possibility of the application of nanocabon composite materials with ABS base resin used widely in industry for the purpose of innovative strength increment of 3D printed products. To clarify each characteristic of C60, CNT and graphene to ABS resin composites, these three-type nanocarbon composite specimens were fabricated. The fabrication method with a uniform composite material reinforced with distributed each nanocarbon have established on our own. The uniform and dispersion of nanocarbon around ABS base powder particles should be the key point for fabrication of specimen by melt and solidification method. We applied our original technique using ultrasonic vibration with isopropyl alcohol as a solvent for 4 hours. And we investigated the optimal composition rates of each composite material. Each pellet-type solidified specimens was prepared at about 500 K for 30 minutes by atmospheric furnace cooling.
As the result of one of representative mechanical property, Vickers hardness for each specimen excellently increased up to about 10 % for 7.0 wt.% C60 and 7 % for 1.0 wt.% graphene in comparison with the value of pure ABS resin bulk sample. The evaluation of important other mechanical properties such as pulling strength, break strength, fatigue strength, elastic modulus and so on have been examined in detail. These results should give us great conclusive evidence for achievement of this study.
