Influential analysis of fused deposition modeling process parameters on the wear behaviour of ABS parts

Fused deposition modelling (FDM) is an additive manufacturing process (AM) that comes under rapid prototyping technique in which parts can be manufactured at a faster rate and even more complex parts can be manufactured with high accuracy at low production cost compared to conventional manufactur- ing methods. This research work is aimed to provide insight on the dependency of wear properties on various process parameters of the FDM printed acrylonitrile butadiene styrene (ABS) parts. The process parameters considered in this study are layer thickness, infill density and infill pattern. Unidirectional sliding tests were performed with pin on disc wear testing apparatus. It is found that the wear rate and the coefficient of friction of FDM printed parts can be controlled by varying the process parameters to attain the optimal state which is very difficult in conventional methods. Among the three process parameters layer thickness is found to be a dominant one because it is directly proportional to the wear rate. The infill pattern combined with infill density produces rapid variation in wear performance. (C) 2019 Elsevier Ltd. All rights reserved.
