Study of parametric optimization of fused deposition modelling process using response surface methodology

FDM(fused deposition modelling) is a RP(rapid prototyping)technique used to manufacture prototypes on additive manufacturing technology.The material used is ABS(acronitirile butadiene styrene) plastic.The prototypes are made layer by layer addition of semi molten plastic and their joining by diffusion welding.In the present study effect of different parameters on response is studied.RSM(response surface methodology) is used to build a regression model which can represent response in terms of different parameters. Influence of the process parameters on each factor is essentially studied and regression equation is built for each of strength under study.By using ANOVA analysis significant factors are considered and unsignificant factors are left out. After getting regression equation an optimized solution is obtained for each strengthby using a suitable mathematical software.
