碩士 === 萬能科技大學 === 材料科學與工程研究所在職專班 === 102 === To investigate property of ABS and perfect difference by using different scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermogravimetry analysis (TGA) and Tensile strength test, in this thesis, we discuss about ABS which would be produced during the process of 3D-printing technonlgy and also be produced into three kinds of different modes—Hollow, Solid and Strong. After experiments we can learn that in the dynamic mechanical analysis (DMA), there is no big difference between three models.What worthy to say is that the tanδ of Solid is the lowest one,it shows that its viscoelastic would be better than the others. In the tensile strength experiment, Modulus in Strong has lower coefficients which mean it has good elasticity. However it has a great impact in toughness properties of ABS material, it is a kind of material with no rigid and mechanical properties in nature. In addition, thermal gravimetric analysis shows that ABS not only has a comparatively higher cracking temperature but has a good heat resistance.According to the different scanning calorimetry (DSC),ABS is a kind of non-crystalline copolymer copolymerized by three monomers which shows good processability of thermoplastics.
