| Abstract Scope |
Thermoplastic Polyurethane (TPU) is best known for its elastic and flexible qualities. In this research, commercially available nickel-titanium alloy (Nitinol) shape memory alloy (SMA) wire is embedded within a 3D printed TPU substrate. 3D printing “Pause and Go” approach is being considered to insert the pause during the printing of the specimen and embeds the SMA wire. After embedding the wire, printing is continued to complete the fabrication of the specimen with embedded wire. Making multiple specimens, these thin strips of TPU with nitinol SMA embedded are assembled to mimic a clamp fixture in the shape of a claw machine. It is expected that, due to the external thermal and electrical excitement, SMA will regain the treated shape which ultimately demonstrates the actuation. This research explores the low-cost manufacturing of soft robotics elements which can be used in many real-life applications in medical, aerospace, and domestic appliances. |
