Abstract : Rapid prototyping is used to manufacture parts for easy validation and proving of new design concepts. Fused Deposition Modelling is an additive manufacturing process and most commonly used technique in rapid prototyping, which generates a three dimensional physical part from a 3D CAD model. Many a times, bulky components are made using this method. However, it takes a lot of time and unnecessary filling of the solid resulting in larger usage of proprietary material. One method to reduce weight and time could be by making it hollow. Hollow parts do not have the same strength and they require to be reinforced. This paper explores the different kinds of inner filling of these bulky parts and how they compare among themselves in the strength of the component. In the present study, a plastic gear used in Leyland wiper motor is replaced by a prototyped gear made by fused deposition modelling method. Analysis was carried out to determine the bending and contact stress. The analysis results were compared with theoretical results. © Research India Publications.
