The advancement in digital 3D printing technology is further evolved with the development of new deposition materials. The materials for fused deposition modelling are successfully implemented in the field of medical and electronics engineering application for printing actual working products. The present paper deals with the effect of three different raster orientation angles and a 0.5 wt.% dope of graphene on the tensile strength of samples made of acrylonitrile butadiene styrene as per ASTM-D638 standard. It is interesting to observe that the samples prepared with a raster orientation of 0° degree with respect to the longitudinal axis showed highest tensile strength followed by 45° and 90°. The similar trend is also observed with the samples doped with 0.5 wt.% graphene although the tensile strength is observed to increase by 50% than that of the samples of plain ABS. In order to explore the effect of strain rate on tensile strength of plain and doped ABS specimens, the experiments were also performed at a cross head speed of 300mm/min and found that the strain rate increases the tensile strength by 2 to 3 times depending upon the raster orientation angle during fabrication of the samples.
