Dynamic Mechanical Properties of ABS Material Processed by Fused Deposition Modelling

چکیده
This paper presents a study of dynamic mechanical properties of Fused Deposition Modelling (FDM) rapid prototyping processed material Acrylonitrile butadiene styrene (ABS). It involves the measurement of modulus and damping properties of the material as it is deformed under periodic stress. In this study, frequency sweep is performed in DMA 2980 equipment to determine modulus, damping and viscosity values. The effect of FDM process parameters of built style, raster width, and raster angle over these properties is investigated. Frequency sweep experiment is done with the range of 10 Hz to 100 Hz in three different isothermal temperatures. The effect of temperature over these properties is also determined. Results show that solid normal built style gives more strength when compared to double dense and sparse built styles. It is also found that the loss modulus increases with increase in temperature, but viscosity values decrease with the increase in the temperature.
