As a result of the project “5-DOF FDM Printer Design and Manufacturing,” carried out under
the collaboration signed between the Scientific and Technological Research Council of
Turkey (TÜBİTAK) and the Ministry of Science, Research and Technology of Iran, an
original 3D printer system has been developed and received a patent.
The study, conducted under the leadership of Prof. Dr. Ahmet Dumlu, Faculty Secretary and
Faculty Member of the Department of Electrical and Electronics Engineering at the Faculty of
Engineering and Architecture, with Prof. Dr. Kağan Koray Ayten and Research Assistant
Gürkan Kalınay as researchers, resulted in a 3D printer system officially registered by the
Turkish Patent and Trademark Office.
The system, which has five degrees of freedom (5-DOF), significantly reduces the need for
support structures compared to conventional FDM printers, while shortening production time
and increasing efficiency. The developed design allows for more flexible and highly precise
manufacturing of parts with complex geometries.
Project leader Prof. Dr. Ahmet Dumlu stated that the developed system is not only a technical
improvement but also introduces a new approach to production processes. Dumlu said, “With
this five-degree-of-freedom design, we aim to eliminate many constraints encountered in
additive manufacturing. The reduced need for support structures saves material and minimizes
post-processing. This creates significant advantages in terms of time and cost.”
Emphasizing the gains in knowledge sharing and technical capacity development achieved
through the international collaboration, Dumlu noted that the patent registration is a tangible
indicator of the university’s R&D competence. He also stated that the developed system can
be effectively used both in academic research and in industrial applications within advanced
manufacturing technologies.
