Abstract

Direct ink writing (DIW) has emerged as a promising manufacturing technique owing to its precise spatial, temporal, and controlled multi-material deposition capabilities, which facilitate the fabrication of well-defined geometrical structures from a broad range of materials. As an alternative to costly chemically tailored DIW functional inks, herein, we present a detailed study of well-known inexpensive, commercially available polymeric thermoset elastomers as potential inks for DIW 3D printing. Chemical compositional and rheological characterizations were performed to compare three commercial acrylic elastomer inks, while printability and various performance properties of the corresponding 3D-printed structures were evaluated.
