The properties of plastic filaments have an essential role in the printability and properties of printed products made by 3D printing FDM. Therefore, graphite oxides reinforced ABS plastic filament were fabricated to investigate the properties change for the purpose of improving the properties of products printed from ABS plastic. Graphite oxides reinforced ABS plastic filament with 1 %, 3 % and 5 % content, respectively, was fabricated and tested for mechanical properties, printability, and printing temperature, which showed some changes in properties compared to original ABS plastic filaments.
