Title: Strength Optimization and Strength Prediction of Fused Deposition Modelled Specimens Based on Process Parameters
Keywords: fused deposition modelling, strength optimization, strength prediction, design of experiment, process parameters
Abstract: There are many factors, which influence the strength of parts produced by Fused Deposition Modeling. In this study, the effects of main manufacturing process parameters are quantified and optimized using the Design of Experiment approach, in order to produce components with higher tensile strength. First, the main manufacturing parameters, which can be set in the slicing software, are explained. Ten parameters are selected for strength optimization, using standard tensile test specimens. The strength and elasticity modulus resulting from the parameters sets are determined and evaluated. It was found that the nozzle diameter, top and bottom layer orientation, infill amount and layer height have a major influence on strength. Additionally, the effects of filament color and time after building are examined and their effect on strength was found to be negligible. A regression model is developed to calculate optimized parameter sets.
