Keynote Lecture: Additively Manufactured Biomimetic Polymers

Dr. Ozgur Keles, Chemical and Materials Engineering Department, San Jose State University
Register: Here
Additive manufacturing (AM) is increasingly used for biomedical, automotive, space, defense, transportation, and consumer product applications. Fused deposition modeling (FDM) is most common AM technique that can produce polymer, composite, metal, and ceramic materials. FDMed materials, however, contain pores between the deposited beads. Moreover, we can intentionally add pores to any kind of design to decrease weight or to add functionality, such as heat or mass transport. These pores reduce mechanical properties and introduce variations in mechanical properties. Despite the increasing use of FDM, the effect of porosity on the mechanical behavior of FDMed materials are unclear. Our recent work showed that intentional vibrations or biomimetic deposition paths can be used to double mechanical reliability of FDMed polymers and polymer matrix composites. In this talk, I will discuss the origins of the mechanical reliability in porous polymers and deviations from Weibull statistics. In addition, I will detail how we can improve strength and toughness of porous polymers. Biomimetic meso-structure and vibration-assisted FDM approaches will be described to improve reliability in FDMed materials.

Dr. Ozgur Keles is an Assistant Professor of Chemical and Materials Engineering at San Jose State University. Dr. Keles received his B.S. and M.S. degrees from the Department of Metallurgical and Materials Engineering at Middle East Technical University, and his Ph.D. in Materials Engineering from Purdue University in 2013. Following, he joined Illinois Institute of Technology as a research associate and lecturer, where he investigated the reliability of porous glasses and porous pharmaceutical compacts. His work on the deviations from Weibull statistics in porous ceramics was highlighted at the Gordon Research Conferences and awarded by the American Ceramic Society. He is also a photographer and digital artist who uses aesthetically appealing images and computer visualizations to improve student engagement, to aid student learning, and to foster creativity in engineering students. His work at the intersection of engineering, education, and arts was also highlighted in the The Member Journal of TMS. His current research interests are stochastic fracture of additively manufactured materials and ceramics, mechanical behavior of quantum dot reinforced hierarchical composites, and virtual reality applications in engineering education.
