On Wednesday, March, 4th ,2026 Al-Khwarizmi College of engineering held a master thesis defense in the field of Automated manufacturing engineering titled “Effect Of 3D Printing Process Parameters on Product Quality and Production Rate of Additively Manufactured Parts”, for the master candidate (Mustafa Taha Khudaer) at the defense hall, where a degree of passing with distinction was awarded for his research findings.

The committee is composed of the following members:

  • Professor Dr. Ali Hussein Muhammad, Chair
  • Assistant Professor Dr. Salah Salman Abdelkarim, Examiner
  • Lecturer Dr. Yahya Muhyi Hamad, Examiner
  • Assistant professor Dr. Karim Nimah Salumi, Supervisor

This thesis shed lights on the accelerated development of 3D printing techniques, which make a revolution in the field of modeling and additive manufacturing, but it still faced a substantial challenge represented by achieving balance between production rate and final products quality. Moreover, the study highlighted that most literature focused on the effect of layer thickness and printing speed, while paying less attention to the acceleration variable, however, its importance in improving productivity.   

This thesis investigates how the combination of speed, layer thickness, and high acceleration influences the efficiency, surface finish, and mechanical reliability of 3D-printed PLA. The research highlights that high acceleration is a primary driver of productivity, it can reduce print times by up to 45%, though it can negatively impact surface finish.

The study also determined the optimal values for operating parameters to achieve balance between mechanical properties and productivity through adopting thin layer thickness, moderate acceleration, and high printing speed. The study also included development of appropriate mathematical model to improve printing performance at high speed, as well as making a future plan to process thermal constraints and integrating smart hardware into the industry 4.0 ecosystem to create more efficient production environments.
