Dynamic mechanical properties of ABS material processed by fused deposition modelling

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