Abstract Scope Direct ink writing of 3D structures has many advantages, specifically in this study is the ability to print multiple materials with tailored functionalities in a controllable and single-step process. It further allows for net shape printing in ambient conditions of a wide range of materials normally incompatible with each other or with other printing systems. In this work, custom-designed coaxial nozzles have been 3D printed using a stereolithography printer. These nozzles were then used to co-extrude conductive ink cores within shells of ambient or UV-cured elastomeric shells. Initially, conductive fibers were printed to study the interfaces, curing, and electro-mechanical properties of the dual ink system. Further, the core-shell fibers were printed into strain gages and incorporated within direct ink written 3D soft robotic pneumatic actuators. Infrared spectroscopy, nuclear magnetic resonance, and optical and electron microscopy were performed to further characterize the printed structures.
