Abstract
- This paper presents the dynamic mechanical and thermal analyses of the inkjet 3D printed materials of the Objet Connex 500 printer by Stratasys. The Objet Connex printer uses different ratios of distinct base materials to produce materials with homogeneous bulk properties using an inkjet process. Small dots of the liquidized polymer base materials are deposited on the print bed and cured with ultraviolet light. This paper examines the materials produced using the base materials TangoPlus (FLX930) and VeroWhitePlus (RGD835), which provide materials with varying levels of rubber-like characteristics. These materials are increasingly used to create prototypes of vibration suppression systems. To better understand the damping properties of these materials, it is necessary to characterize their viscoelastic properties. In this work, the viscoelastic properties are characterized by measuring the frequency and temperature dependent complex modulus. A dynamic mechanical analyzer is used to measure the complex moduli of four materials for a range of frequencies and temperatures. The time-frequency equivalence is used to determine a relationship between frequency and temperature; producing a master curve of the complex moduli over a wide range of frequencies and a single reference temperature. The effects of using tensile versus cantilever testing configurations and the effects of print direction are also discussed.
