Minimizing error on circularity of FDM manufactured part

Abstract Additive manufacturing (AM) is a technology rapidly growing on a number of industrial sectors. It provides design freedom and ecological/environmental advantages and highly 3D complicated parts also we can make without any restriction. Several investigators have established the direct and indirect use of Fusion Deposition Modeling (FDM) manufactured parts as final products in industrial application, such as turbine blades the concept of rapid tooling and rapid casting of certain aluminum parts using FDM parts as patterns. Albeit industrial application all the component should be expected as highly accurate parts to give up the better output to the end user. The present research work investigates the relationship with the three process parameters namely fill density, horizontal and vertical orientation of part with circularity of FDM manufactured parts. In this research ABS material chosen for experimentation, design of object is made by Creo 3.0 software and is converted to stl file imported to uPrint SE FDM machine and the part is manufactured. The DOE, Taguchi method and ANOVA are used to obtain the optimum combination of the parameter for minimum circularity error on both inner and outer circle. The causes for variation are found and recommended for industrial best fitness functions.
