Master's student Zainab Raheem Habeeb - Prothesis and Orthosis Engineering Department discussed her thesis tagged:

Pre-Processing and Surface Reconstruction of Points Cloud for Method of Additive Manufacturing of Custom Orthoses

Where the discussion took place on Monday, corresponding to 26/6/2023 in the hall of the Department of Biomedical Engineering. The discussion committee was chaired by Faraj Mahal Muhammad / University of Technology / Department of Electromechanical Engineering with the membership of Prof. Dr. Mahmoud Rashid Ismail and Assistant Professor Dr. Ammar Essam Saleh from the Prothesis and Orthosis Engineering Department at Al-Nahrain University. The thesis was supervised by Professor Dr. Ahmed Abdel-Samie Abdel-Wahhab from the Prothesis and Orthosis Engineering Department at Al-Nahrain University and Assistant Professor Dr. Abdulkader Kadauw, from Freiberg University/German.

In this work, orthoses devices were designed using computers with different materials in terms of thickness and relative density. First, reverse engineering was used, which refers to a set of techniques represented by capturing human data for foot and leg using a 3D scanner. Exporting and modifying the file within the 3D modelling program using the Computer-Aided Design (CAD) program. Exporting the file in STL format for the purpose of printing the orthoses using Computer-Aided Manufacturing (CAM) represented by the Fused Deposition Modelling (FDM) technique, which is one of the additive manufacturing techniques.

Finally, the design was verified using Computer-Aided Engineering (CAE) represented by the ANSYS program, to find the total deformations, maximum stresses and safety factors for each of the carbon fibres and polylactic acid. The numerical results showed that the safety factor about (2.062) for carbon fibres and (1.593) for polylactic acid plus in static structure case. This design is characterized by less weight and time manufacture compared to designs used by traditional methods.

The thesis was accepted as a fulfilled the requirements for obtaining a master's degree, with a grade of (very good).
