Reliability of Fused Deposition Modelling (FDM) Components on Fatigue Cycles to Failure Using Weibull Analysis


Article Preview

Application of fused deposition modelling components are gaining popularity in functional application. In order to use these components directly for functional application, reliability in service has to be acheived. A Reliability analysis was caried out on components manufactured by fused deposition modelling. A standard test specimen as per ASTM was prepared and tested for fatigue cycles to failure. Bending stress was calculated prior to the fatigue testing by varying the slice thickness. Fatigue test was carried out with differnt loading condition. Fatigue test results were subjected to weibull analysis to determine the reliability of FDM components. The Weibull design values were calculated and Weibull distribution plot for failure was plotted and analyzed. Estimation of reliabilty for different cycles to failure was also found out.
