Abstract

Fused Deposition Modeling (FDM) is one of the popular Additive Manufacturing (AM) processes that can provide functional prototypes of Acrylonitrile butadiene styrene (ABS) plastic. As AM processes build the component in a layer-by-layer manner, they tend to be anisotropic in nature. The fill pattern and process parameters can affect the strength of parts produced in AM. Hence, a study of effect of process parameters like fill density, fill pattern, orientation etc on the mechanical properties was felt necessary. This work presents the results of different types of ABS components fabricated while varying the process parameters and their effect of mechanical strength of component. Young’s modulus and ultimate strength were used for the same. The results will help the user in identifying the right process parameters for a desired object.
