Fused Deposition Modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping and production applications. It works on an "additive" manufacturing principle by laying down material in layers. A plastic filament or a metal wire is unwound from a coil and supplied to produce a part. Taguchi method is a statistical method developed by Genichi Taguchi to improve the quality of process in engineering, biotechnology, marketing and advertising. It involves the identification of proper control factors to obtain the optimum results for the process. Orthogonal Arrays are used to decide on the set of experiments. Results of these experiments are used to analyze the data and predict the quality of the process used. The objective of this work is to adapt Taguchi and Full factorial methods to fused deposition modeling process. L9 orthogonal array and S/N ratio are used to study the performance characteristics on build time. Print speed, layer thickness and extrusion density are the parameters selected. Accordingly, a suitable orthogonal array (L9) is developed and experiments performed. Based on analysis of S/N ratio, optimum parameter values are obtained and the confirmation experiments are carried out by using full factorial method.
