Abstract

3D printer was used to fabricate acrylonitrile–butadiene–styrene (ABS) to identify the friction and wear. This new adaptation technology is starting to attract industry especially medical field since it has longer life span and low cost. Previous investigation focuses the influence of hardness, tensile test and temperature effect. However, the understanding regarding tribological properties need more research. It is great to identify application that suitable since ABS is one of biocompatible material. The aim for this study to compare the tribological performance between 3D printer ABS and molded ABS under dry and wet conditions. The result of coefficient of friction of both samples were taken using ball-on-disc machine. Both samples were formed in disc shape for experiment. 3D printer and molded ABS that tested under wet condition were using paraffin oil as lubrication and others parameter were set as constant such as temperature (27℃) and speed (120 rpm). Different load was applied from 20 – 40 N throughout the experiment both sample and conditions. The result shows that molded ABS has the lowest COF than 3D printer ABS under both conditions. However, specific wear rate of the experiment show 3D printer had the lowest wear compared to molded because of it has porosity to retain the fluid in 3D printer sample. As conclusion, 3D printer sample is good wear resistance compared to molded meanwhile COF improvement need further study
