Area of Science:

  • Materials Science
  • Additive Manufacturing
  • Robotics

Background:

  • Developing advanced materials for smart applications is crucial.
  • Three-dimensional (3D) printing offers versatile fabrication capabilities.
  • Four-dimensional (4D) printing, which involves time-dependent shape changes, requires novel stimuli-responsive materials.

Purpose of the Study:

  • To propose a novel and simple fabrication method for magnetic microfibers using 3D printing.
  • To demonstrate the 4D printing capabilities of these magnetic microfibers.
  • To explore the potential applications of these microfibers in smart sensors, actuators, and bionic motion systems.

Main Methods:

  • Fabrication of a ferromagnetic 3D printing filament by mixing neodymium-iron-boron (NdFeB) and polylactic acid (PLA).
  • Characterization of the filament's properties (mixing ratio, magnetic, mechanical, rheological).
  • Thermal extrusion of the filament through a 3D printer nozzle to create microfibers of varying dimensions.
  • Magnetization of printed microfibers to achieve a permanent magnetic dipole moment.
  • Demonstration of 4D printing through controlled deformations of magnetized microfibers under magnetic fields.

Main Results:

  • Successfully fabricated magnetic microfibers with controllable thicknesses (80-500 μm) and lengths (<5 cm) using 3D printing.
  • Achieved permanent magnetization in the microfibers, enabling them to act as magnetic dipoles.
  • Demonstrated that microfiber deformation in 4D printing can be customized by adjusting the mixing ratio, thickness, and length.
  • Observed unique undulating and oscillating motions in bionic motion actuator applications.

Conclusions:

  • The proposed filament stretching 3D printing method is a simple and effective way to produce magnetic microfibers.
  • Permanently magnetized microfibers exhibit significant potential for use as smart sensors and actuators.
  • The 4D printing capability of these microfibers opens avenues for advanced robotic and biomedical applications.
