Area of Science:

  • Biomimetics and Bioinspired Design
  • Additive Manufacturing
  • Assistive Technology Engineering

Background:

  • Growing demand for accessible, personalized assistive devices.
  • Need for innovative approaches in engineering education.
  • Limited integration of bioinspired design and digital fabrication in current curricula.

Purpose of the Study:

  • To present the outcomes of an international course on "3D Prosthetics and Orthotics."
  • To enable undergraduate students to develop bioinspired assistive devices using additive manufacturing.
  • To demonstrate the value of combining nature-inspired principles with digital fabrication and international collaboration.

Main Methods:

  • Project-based learning approach integrating theoretical and hands-on modules.
  • Utilized digital modeling (CAD), simulation (CAE), and fabrication (CAM).
  • Employed the Mao3D open-source methodology for design and fabrication.

Main Results:

  • Developed functional prototypes including a hand prosthesis (Fin Ray effect), a modular finger prosthesis (tendon-muscle antagonism), and a cervical orthosis (stingray morphology).
  • Prototypes were digitally modeled, mechanically analyzed, and physically fabricated using open-source, low-cost methods.
  • Fostered interdisciplinary teamwork to address real-world rehabilitation challenges.

Conclusions:

  • Bioinspired design and additive manufacturing can be effectively integrated into engineering education.
  • This approach generates functional, socially impactful health technologies.
  • International collaboration enhances the development of inclusive, low-cost assistive innovations.
