Abstract
The effects on viscoelastic and thermal properties of fused deposition modeling (FDM) parts fabricated by using Bakelite and ceramic reinforced acrylonitrile butadiene styrene (ABS) based alternative feedstock filaments were evaluated over a wide range of temperature. The dynamic mechanical analysis (DMA) realized the changes in storage modulus, loss modulus and loss factor for reinforced ABS composite materials. The comparative study with respect to virgin ABS material highlighted that, the composites with higher loading of reinforced particles showed maximum storage modulus. A positive shift of loss factor peaks towards higher temperature and reduction in peak height of the composites, validates their suitability to use as feedstock filament material for FDM system. Overall the reinforcement of filler materials in ABS matrix has resulted in enhanced viscoelastic properties which are compared with virgin ABS material thus increasing the range of rapid tooling and rapid manufacturing with FDM system.
