On Monday, March, 2nd ,2026 Al-Khwarizmi College of engineering held a master thesis defense in the field of Automated manufacturing engineering titled “Design and Manufacture of Below-knee Prosthesis Limb”, for the master candidate (Daniah Saleem Jwair) at the thesis defense hall, where a degree of passing with distinction was awarded for her research findings.
The committee is composed of the following members:
- Professor Dr. Kadhim Kamil Resen, Chair
- Assistant Professor Dr. Thamar Harith Ali, Examiner
- Lecturer Dr. Marwan Ali Salman, Examiner
- Assistant Professor Dr. Ahmed Zidan Muhammad, Supervisor
- Assistant Professor Dr. Huda Hatem Dalif, Supervisor
This study aims to design and fabricate a custom transtibial prosthetic socket using CAD/CAM and 3D printing. The socket was 3D scanned, modeled, printed in PETG, and evaluated through gait analysis and FEA.
Results showed good gait symmetry (84.7%) and low stress under a 600 N load, confirming structural safety and the effectiveness of the digital manufacturing approach.
What mentioned above can be concluded as digital manufacturing and 3D printing reduce health risks and improve efficiency. CAD/CAM with 3D scanning enables accurate, fast, and comfortable socket design. The lightweight PETG 3D-printed socket showed good gait symmetry (84.7%), and FEA confirmed its stability and safety under a 600 N load.
Hence, future work should be focusing on long-term evaluation of 3D-printed sockets, developing of advanced materials (e.g., fiber-reinforced composites), and studying the effect of printing parameters on socket performance. Additionally, integrating AI could enable fully automated and optimized socket design.
