Abstract
Acrylonitrile butadiene styrene (ABS) is a widely used engineering polymer for various applications as it is of low cost and easily machined. The present work aims to study the effect of build orientation and butadiene content on the tribological properties of ABS parts made by Fused filament fabrication (FFF) process. Fabrication is done on Prusa cura I3 Bear upgrade machine considering the build orientation as the main parameter with two different grades of ABS. Specimens are fabricated with two different orientations, i.e., flat and on edge. Wear test is conducted on the prepared specimens using pin on disc tribometer. From the test results, it was found that ABS with 20% butadiene has a high wear rate compared to ABS with 30% butadiene. Maximum wear rate is observed on an on-edge prepared specimen with 20% butadiene at 20 N load, 200 rpm.
