    Towards Sustainable Manufacturing: a Review and Future Directions in Additive Manufacturing of Fiber-Reinforced Polymer Composites
    (Springer Science and Business Media B.V., 2025) Türkcan, M.Y.; Tetik, Halil; Kurt, B.; Dede, Mehmet İsmet Can; Karaş, B.; Tetik, H.; Shokrani, A.; Dede, M.İ.C.
    The United Nations Sustainable Development Goals (SDGs) provide a global framework for addressing critical challenges such as climate change, resource scarcity and sustainable industrialization. With increasing demand for products and improving quality of life, linear consumption of materials and resources following the “take-make-waste” is no longer possible. As such, innovative solutions are increasingly necessary to enable circular economy in manufacturing. Additive manufacturing (AM) has emerged as a transformative technology in achieving SDGs by enhancing resource efficiency and minimizing waste. Fiber reinforced composites are a promising application of AM, as they offer the potential to optimize material use, reduce labor and support sustainable production practices. However, there is an urgent need for considering circular economy strategies, life cycle assessment (LCA) frameworks and effective recycling at the end of their lifetime. This study examines additive manufacturing systems for fiber-reinforced composites, their environmental impact and exploring the potential contributions of robotic integration in composite manufacturing to enhanced sustainability. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

    Modelling and Control of a 3-Rrs Parallel Manipulator
    (Izmir Institute of Technology, 2016) Tetik, Halil; Kiper, Gökhan
    The focus of this thesis study is to model and control a parallel robot manipulator located in Rasim Alizade Mechatronics Laboratory (Izmir Institute of Technology Mechanical Engineering Department). The purpose of this robot is to manipulate heavy payloads. It is considered as the base part of a hybrid manipulator. This thesis study deals with a 3-RRS parallel manipulator with 3 identical limbs. Each limb comprises two parallel revolute joint axes. The manipulator has a base and a moving platform which are in the shape of equilateral triangles. The mobile platform of this manipulator has 3-degrees-of-freedom: it can rotate around x- and y-axes and translate along the z-axis. To obtain the mathematical model of the parallel manipulator, firstly the mobility analysis is performed. Then, a constraint analysis is performed to obtain the dependent pose parameters of the moving platform in terms of the independent parameters. Following that kinematic, singularity, workspace and inverse dynamic analyses are performed. To validate the mathematical model of the PM, several simulations are run in MATLAB/Simulink R environment. Once the mathematical model is validated, the control studies are carried out. The motion of the 3-RRS PM is controlled by activating stepper motors with two different controllers (a CNC controller and a PCI card). To obtain a desired motion of the moving platform, firstly the desired task space coordinates of the moving platform are transformed into joint space coordinates using inverse kinematics. With the CNC controller a trapezoidal velocity, with the PCI card a trapezoidal jerk profile is generated. To test the control over the PM, 3 magnetic encoders are attached to the shafts of input links at each limb. Furthermore, a 3-axis gyroscope is attached to the center of the moving platform to track its rotational trajectory.

    Process improvement in the steel mold machining for aluminum alloy wheel low pressure casting industry
    (01. Izmir Institute of Technology, 2024) Akbaşak, Sancar; Tetik, Halil
    Alçak basınçlı döküm yöntemi ile jant üretim endüstrisinde, Dökümhane bölümleri için sürekli üretim hatları gereklidir. Gerekli üretimi elde etmek için, kalıplar dökümhanelerde hazır olmalıdır. Bu nedenle, alçak basınçlı döküm kalıplarının üretim süresi mümkün olduğunca kısa olmalıdır. Üretimi en üst düzeye çıkarmak için mevcut kapasiteyi kullanmak, daha fazla yatırım yapmaktan çok daha önemlidir. Bu, operasyonların kapsamlı bir şekilde gözden geçirilmesini, süreçler arasında görevlerin dengelenmesini ve en verimli üretimi elde etmek için operasyon sürelerinin azaltılmasını gerektirir. Zamanla daha büyük jant boyutlarına olan artan talep, alt maça için daha uzun üretim sürelerine neden olur. Daha fazla yatırım yapmaktan ziyade, mevcut kapasiteyi en üst düzeye çıkarmak çok önemlidir. Bu, operasyonların kapsamlı bir şekilde gözden geçirilmesini, süreçler arasındaki görevlerin dengelenmesini ve en verimli üretimi elde etmek için operasyon sürelerinin azaltılmasını gerektirir. Bu tezin amacı, üretimin ortasında yapılan ısıl işlem aşamasını kaldırarak toplam üretim süresini azaltmak ve süreci iyileştirmektir. Bu araştırmanın amacı, yalın üretim ve değer akış haritalama, talaşlı imalat makine parametresi optimizasyonu, takım seçimi, makine verimliliği ve üretim hattı dengelemesini kullanarak süreçleri inceleyip üretim sürecini etkileyen unsurların kapsamlı bir şekilde anlaşılmasını sağlamaktır. Değer akış haritalama kullanılarak yeni bir üretim yöntemi önerilmiş ve uygulanmıştır. Ayrıca, yeni üretim tekniğinin neden olduğu sorunların üstesinden gelmek için Taguchi yöntemi ile deney tasarımı kullanılarak işleme parametre optimizasyonu yapılmıştır. Önerilen üretim yönteminin uygulanmasıyla operasyon sayısının 12'den 8'e düşürülmesi, işçilik süresinin %2.35 azaltılması, teslim süresinin %42.65 azaltılması, kapasitenin %2.35 arttırılması, seçili makinelerde kapasite dengelenmesi, makine parametrelerinin optimizasyonu gibi birçok iyileştirme sağlanmıştır.

    A Comparative Study of Attention-Augmented YOLO Architectures for Defect Detection in Fused Deposition Modelling
    (Institute of Electrical and Electronics Engineers Inc., 2025) Cezayirli, H.; Tetik, H.; Dede, M.I.C.; Phone, W.L.; Alkan, B.
    Additive manufacturing (AM), particularly fused deposition modelling (FDM), facilitates the fabrication of complex geometries with increasing flexibility and efficiency. Ensuring consistent print quality in FDM processes necessitates the development of accurate defect detection mechanisms. Attention-augmented YOLO (You Only Look Once) models have emerged as a promising solution for addressing this challenge. In this study, we systematically benchmark and evaluate the performance of YOLO architectures enhanced with attention mechanisms within the context of FDM 3D printing applications. The models were trained and evaluated using representative defect datasets. The attention-augmented models demonstrate improved detection performance. © 2025 IEEE.

    Introducing magnetic properties to aerogels not only opens new application areas but also enhances their performance in various applications. Herein, we report a novel 3D magnetic agar nanocomposite aerogel (3D-MANCA) with outstanding characteristics such as high porosity, magnetic property, rapid swelling behavior, and a unique stimuli-driven electrical conductivity. Agar and nanocellulose mixture were selected as the matrix material, while magnetic Fe<inf>3</inf>O<inf>4</inf> nanoparticles, CuO nanoparticles, and graphene nanopowder were incorporated as functional additives. 3D-MANCA obtained after a uni-directional freeze casting process exhibited a highly-ordered microporosity. It showed excellent magnetic properties and methylene-blue adsorption capability and a great performance as humidity sensor. © 2026 The Author(s).

    (Springer Verlag, 2018) Tetik, Halil; Kiper, Gökhan
    Identifying singularity manifolds of parallel manipulators analytically is a hard task due to their complex kinematics and passive joints. This study proposes to use the geometrical conditions of singularities in order to identify the singularity manifolds for a 3-RRS parallel manipulator. The singularity surfaces for both inverse and forward kinematics singularities are obtained and plotted.

    Computing the SafeWorking Zone of a 3-RRS Parallel Manipulator
    (Springer Verlag, 2017) Patel, Dhruvesh; Kalla, Rohit; Tetik, Halil; Kiper, Gokhan; Bandyopadhyay, Sandipan
    Determination of the safe working zone (SWZ) of a parallel manipulator is a one-time computational task with several permanent benefits. As this sub-space of the workspace of the manipulator is free of both the loss- and gain-type singularities, link interference, as well as physical joint limits, the manipulator can move freely in this space. Moreover, if the natural choice of a convex-shaped SWZ is adhered to, then point-to-point path planning inside the SWZ always has a trivial solution, namely, a segment joining the two points, which is guaranteed to be inside the workspace. In this paper, the SWZ of the 3-RRS existing in the Izmir Institute of Technology has been computed. Starting with the geometry of the manipulator, the loop-closure constraint equations have been derived. The singularity conditions are obtained based on the singularity of certain Jacobian matrices associated with the constraint functions. The interference between the links are detected by first encapsulating the links in rectangular parallelepipeds, which are then discretized into triangles, and subjected to collision tests between the relevant pairs of triangles. Using these theoretical developments, the SWZ is computed. The numerical results are depicted graphically.
