In this study, samples reinforced with continuous metal wire as both a reinforcing component and a shape memory actuator were printed via the Fused Deposition Modeling (FDM) additive manufacturing method. Shape memory materials are a significant subset of smart materials that can recover their original shape in response to a specific stimulus such as heat, magnetism, electricity, moisture, etc. The stimuli for shape memory materials are generally classified into two main categories: direct and indirect. In some cases, direct stimulation may not be possible for shape recovery, and introducing solutions for adding indirect stimulation capability to these materials can expand their application range. In this study, the chromium-nickel metal wire was used as a reinforcing agent to improve the mechanical properties and introduce indirect stimulation capability to the materials by applying voltage simultaneously using the in-situ impregnation method in the FDM process. Adding continuous fibers through the in-situ impregnation method during the printing of parts significantly enhances the mechanical properties of polymeric samples. According to the obtained results for a 0.15 mm diameter metal wire, the increase in tensile strength for 5% and 10% reinforced samples was 63% and 134%, respectively. The increase in flexural strength for samples reinforced with 5% and 10% metal wire was 10% and 105%, respectively.
