Abstract
Fused Deposition Modelling (FDM) is the most widely used additive manufacturing method to prepare 3dimensional parts made of polymers. Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer made of three monomers acrylonitrile, butadiene and styrene. ABS is of low cost and easily machined with better mechanical and chemical properties. The aim of the present work is to study the effect of butadiene content on the tribological properties of specimens made of ABS by FDM process. The specimens are prepared by considering the process parameter infill percentage (20%,50%,80%) with two different grades of ABS filaments on Prusa cura I3 Bear upgrade machine. Experiments are conducted on pin on disc apparatus to determine wear behaviour. The test results show that the butadiene content and infill density of the specimens affect the wear rate of ABS. Maximum wear rate is observed at 20% infill specimen containing 20% butadiene at 200 rpm 20 N load.
