Abstract

A conventional Fused Deposition Modeling (FDM) machine builds an object layer by layer on a horizontal platform from bottom to top fashion. The major drawback of the FDM machine is limited number of degree of freedom (only 3). Industrial robots with six degrees of freedom are capable to move its end effector in 3D space with high resolution and repeatability. A robot with an extruder as an end effector has the capability to print the objects on multiple planes. In this work, an attempt is made to simulate the FDM process with an industrial robot. Simulation of printing of a cube on horizontal and inclined planes is presented. Tool path for each sliced layer is developed using polygon-filling algorithm. The simulation of printing of 3D objects using 6-axis industrial robot is carried out using ABB RoboStudio simulation software.
