Direct Ink Writing (DIW) is an extrusion-based additive manufacturing method that has the capabilities of precise spatial temporal controlled multi-material depositions, which enhances the fabrication of well-defined geometrical structures based on a wide range of materials. As an alternative to costly chemically tailored DIW inks, commercially available polymeric elastomers were studied as potential inks for DIW. In addition, these elastomers yield potential groundwork for applications such as dielectric properties, battery charge controller, improvement of electrical and thermal conductivity as significant mechanical properties. Chemical composition, viscoelastic and rheological behaviors were optimized on the NovaBond Hybrid Sealant, which is a commercial acrylic elastomer,chemically formulated as Polyvinyl Ether. The evaluation of this elastomer for DIW was performed under different mechanical, thermal and optical properties testing along with their printability.
