Abstract Scope |
In this study, the vibration analysis of 3D printed unfilled and filled thermoplastic copolyester (TPC) has been investigated with the purpose of determining the influence of reinforcement on the properties of 3D printed parts, and study the effectiveness of vibration response as an indicator for mechanical properties. Unfilled TPC filaments and filled TPC filaments containing 10 wt% hydrolyzed soybean hull fibers are used to manufacture bars by fused deposition modeling (FDM). Three raster angles (0°; 90°; 0°/90°) are considered while printing the bars, and the natural frequencies and damping characteristics are measured using free vibration analysis. It is observed that the composite bars display improved mechanical properties and natural frequencies than unfilled polymer. Further, storage and loss moduli obtained from dynamic mechanical analysis (DMA) are used as inputs in Digimat simulations for determining the natural frequencies of the 3D printed bars, which compare well with the experimental observations. |
