Fused Deposition Modelling (FDM) process builds the 3D objects by extruding the material in layer-by-layer fashion from bottom-to-top. In a conventional FDM machine, due to limited degrees of freedom, change in extruder orientation is not possible. Industrial robots with 6 degrees of freedom are capable to move and orient the end effector in 3D space with high resolution and repeatability. The limitation of the conventional FDM machine can overcome by using an industrial robot with a dual nozzle extruder as an end effector. In this work, an attempt is made to print objects with an industrial robot with dual nozzle extruder attached to it. The results showed that the orientation of the extruder can be changed easily so that a strong bonding between the layers is possible while going for dual nozzle extrusion. By extruding the same material with both nozzles, the printing time is less than the conventional FDM process. The methodology adopted for printing the objects using ABB Robotstudio® simulation software and printing a component with ABB IRB1600 industrial robot is presented in this article.
