    Fused Filament Fabrication in Cad Education: a Closed-Loop Approach
    (Sage Publications inc, 2025) Totuk, Onat Halis; Selvi, Ozguen; Akar, Samet
    Integrating low-cost fused filament fabrication 3D printing as a foundation for learning 3D modelling is explored. This method blends traditional computer aided design (CAD) instruction with additive manufacturing possibilities. Experimental results demonstrate increased comprehension speed and reduced learning time. This hands-on approach empowers students by enabling direct engagement with the modelling process. Analogous to reverse engineering, the strategy instructs engineering students from final product to model creation, closing the gap between theory and practice. Incorporating 3D printing bridges this divide, enhancing understanding, creativity and problem-solving. The study underscores technology's influence on learning strategies, aligning with the surge of 3D printing in education. Results link advanced design technology usage to improved student performance, with 3D-printed materials yielding 45% higher grades and 30% faster task completion. This study advocates curricular advancement for design-focused careers through enhanced technology integration and favourable 3D printing model reception.

    Small-Scale Mechanical Properties of Additively Manufactured Ti-6al
    (The University of Texas at Austin, 2020) Totuk, Onat Halis; Haghshenas, M.; Totuk, O.; Masoomi, M.; Thompson, S.M.; Shamsaei, N.; Mekatronik Mühendisliği
    This article aims at studying microstructure and nano/micro-scale mechanical responses of Ti-6Al4V fabricated using a Laser-based Powder Bed Fusion (L-PBF) method. To this end, an instrumented depth-sensing nanoindentation system has been used to assess hardness, Young's modulus, strain rate sensitivity and rate dependent plastic deformation of the alloy at different build Orientations (in the Z-plane and X-plane) at ambient temperature. Indentation tests were conducted at constant proportional loading rate of 15 mN/s in a depth-controlled (hind=2000 nm) testing regime. The Microstructure characterizations were performed using optical and scanning electron microscopy to assess the correlations to the mechanical properties achieved by the nanoindentation testing to better establish structure-property relationships for L-PBF Ti-6Al-4V. It is expected that the fine microstructure, developed by fast solidification during the L-PBF process, to directly contribute to the nanoindentation measurements at different strain rates.

    Modeling and Optimization of a Peano-Hasel Actuator Peristaltic Pump
    (Natl inst Science Communication-niscair, 2023) Mistikoglu, Selcuk; Totuk, Onat Halis
    Peano-Hasel (hydraulically amplified self-healing electrostatic) pumps are crucial devices with unique mechanisms and versatile applications. They simulate muscle contractions to move fluids or materials through tubes. The Peano-Hasel method, a specific design, achieves flow by compressing a segmented tube externally. Exploring the design aspects of Peano-Hasel pumps can lead to advancements in optimizing their performance, efficiency, reliability, and control systems. This paper presents a novel method of peristaltic pumping on soft pipes using Peano-HASEL actuators. In the study, a design evaluation of an external ring-type pump over a PDMS (Polydimethylsiloxane -commonly referred to as silicone) tube containing Newtonian fluids is made, and a novel multi-pouch ring shape design is proposed. Our method utilizes a peripheral and compact design that allows for more efficient sinusoidal pumping action. The close proximity of the rings in the longitudinal direction enhances the effectiveness of the pumping process. The actuator is analytically modeled and optimized for maximum areal contraction and flow rate using a differential evolution algorithm. A MATLAB Simulink Simscape model is generated, and the system is simulated. As a result, an optimal solution for the number of pouches was found to be eight, considering ring geometry and applicability. It was also seen from the simulation that a sinusoidal squeezing scheme of a ring-type pump creates the desired action. Based on the analytical model presented, it has been demonstrated that the optimal flow rate is achieved when there are eight pouches, and they are fully circular after being energized.

    Integrating Multidisciplinary DBR in Mechanical Engineering Education, Challenges, and Opportunities: Innovating ME Education Via Cross-Discipline DBR
    (IGI Global, 2025) Totuk, O.H.; Selvi, O.
    This chapter explores the challenges and opportunities of integrating multidisciplinary design-based research (DBR) into mechanical engineering education. As engineering problems become more complex, there is a growing need for graduates who can work across disciplines. DBR enhances the mechanical engineering curriculum by fostering collaboration, promoting real-world problem-solving skills, and bridging theory and practice. The chapter addresses challenges in implementing DBR, including resistance to change, resource constraints, and assessment issues, while highlighting opportunities for improved student engagement, creativity, and industry partnerships. Case studies of successful DBR integration in mechanical engineering programs are presented, showcasing innovative approaches and outcomes. Finally, the chapter proposes strategies to overcome barriers and maximize the benefits of multidisciplinary DBR, contributing valuable insights for educators seeking to prepare students for the evolving demands of the engineering profession. © 2025 by IGI Global Scientific Publishing.
