| contents | High-aspect-ratio polymer materials are widely utilized in applications ranging from everyday materials such as clothing to specialized equipment in industrial and medical fields. Traditional fabrication methods, such as extrusion and molding, face challenges in integrating diverse materials and achieving complex geometries. Additionally, these methods are limited in their ability to provide low-cost and rapid prototyping, which are critical for research and development processes. In this work, we investigated the use of commercially available 3D printers to fabricate fiber preforms, which were subsequently thermally drawn into fibers. By optimizing 3D printing parameters, we achieved the fabrication of fibers with diameters as small as 200 um having complex shapes, with features down to a few microns. We demonstrated the versatility of this method by fabricating fibers from diverse set of materials, such as fibers with different stiffnesses and fibers with magnetic characteristics, which are beneficial for developing tendon-driven and magnetically actuated robotic fibers. In addition, by designing novel preform geometries, we produced tapered fibers and fibers with interlocking mechanisms, also tailored for use in medical steerable catheter applications. These advancements highlight the scalability and versatility of this approach, offering a robust platform for producing high-precision polymer fibers for diverse applications. |
