Abstract

Shape memory alloys (SMAs) have been widely used to manufacture soft functionally integrated structures by embedding SMA wires into various soft matrices manufactured by conventional molding methods or 3D-printing technologies. 3D printing enables rapid prototyping, custom design as well as manufacturing of parts with complex structures and high resolutions. This article presents a 3D printed elastomeric composite with integrated SMA wire. The matrix of the composite was printed using thermoplastic polyurethane (TPU), with the SMA wire embedded during the 3D printing process. While the SMA is being excited, the deformation of the specimen was measured optically using DIC (Digital Image Correlation) and simulated using ANSYS. This research offers a promising approach for developing SMA-based elastomeric composites with customized shapes, sizes, and performance characteristics.
