Mechanical testing and evaluation of the composite developed through fused deposition modelling

In this paper, a composite material is developed through fused deposition model (FDM). The E – glass fibre is used impregnate in the polylactic acid (PLA) plastic as a composite. The material is developed as per the ASTM standard for mechanical testing. The layer thickness (mm), feed speed (mm/min) and the extruder temperature (°C) are the three main input process parameters used to develop the composite material. The samples developed are ensured to standard dimensions before investigation on mechanical testing. Fusion temperature and layer thickness are the two main input process parameters for making FDM samples. With a minimum layer (0.1 mm) and maximum extruder temperature (201 °C) the FDM processed sample found increased strength. Decrease in temperature cause weak bonding and lead to failure.
