3D Printing technology is slowly making its way into the mainstream manufacturing Processes. Fused Deposition
Modelling (FDM) is one of the most popular techniques of manufacturing objects by 3D Printing. Under tension, two types of
failure phenomenon occur in 3D printed specimen i.e. In-layer & Inter-layer fracture. In-layer fracture is considered to be a
desirable failure type as it signifies that the layer separation is not occurring in the specimen and the fusion bond created is
sufficiently strong which leads to superior tensile strength of the specimen. In this study, we have carried out experiments to
study the effect process parameters like Nozzle Temperature, Printing speed & Rastor Angle has on the fusion bond between the
layers by studying the angle made by the fractured surface with the layer. Poly Lactic Acid (PLA) material and FDM 3D
Printing Method is used for making the testing specimens. Results showed that nozzle temperature & Rastor Angle have
significant effect on tensile strength & In-lay
