- Additive Manufacturing
Background:
- Prosthetic feet are crucial for amputees but are often prohibitively expensive in developing nations.
- Limited accessibility of conventional prosthetic limbs restricts their use for many individuals with special needs.
Purpose of the Study:
- To design an uncomplicated, low-cost prosthetic foot utilizing 3D printer technology.
- To provide an accessible prosthetic solution for a wider range of amputees.
Main Methods:
- Prosthetic foot design using CAD software and analysis via ANSYS.
- Selection of carbon fiber material suitable for 3D printing.
- Mechanical testing (tensile, fatigue) and numerical analysis for an 85 kg patient.
Main Results:
- Carbon fiber demonstrated suitable mechanical properties for 3D-printed prosthetic foot manufacturing.
- Engineering analysis confirmed the prosthetic foot model's reliability and successful design completion.
Conclusions:
- The designed prosthetic foot model, validated through numerical analysis, is reliable for manufacturing.
- This 3D-printed prosthetic offers a viable, cost-effective solution for amputees.
