On Tuesday, October 24, 2023, in Al-Khwarizmi Central Hall, student Taiba Raed Mahmoud, from The Department of Automated Manufacturing Engineering, presented her master’s thesis titled “Assessment of 3D Scanning Techniques in Dental Restorations and Prosthodontics Utilizing CAD/CAM Technology.” The esteemed committee, led by Prof. Dr. Wissam Kazem Hamdan, a lecturer from the University of Technology’s Department of Biomedical Engineering, included members Assist.Prof. Dr. Ahmed Zidan Muhammad and Assist.Prof. Dr. Heba Khaled Hussein from the Department of Automated Manufacturing Engineering at Al-Khwarizmi College of Engineering. This pivotal research endeavor was under the supervision of Assist.Prof. Dr.Nizar Qais Muhammad Nayef.
This study focuses on optimizing the stereo lithography 3D printing process, a vital additive manufacturing technique, for enhanced precision and surface quality. Stereo lithography involves using digital models from computer-aided design to create 3D objects using photosensitive resin solidified by ultraviolet light.
The research explores two scenarios: printing standard cubes and temporary dental bridges, aiming to minimize dimensional variation and surface roughness while maximizing part hardness. Multi-objective optimization is achieved through the Taguchi method and response surface methodology. The study’s findings indicate that the optimal parameters yield accurate cubes and dental bridges with smooth surfaces. Following a comprehensive discussion, the committee unanimously awarded the researcher a degree of distinction for her exceptional work.
