The advances of digital possibilities created an environment where fabrication of form and formwork techniques reconsidered with digital terms. As a new research field in digital fabrication, primarily additive manufacturing has particularly attracted the attention to fabricating complex generative form and formwork. Presently a new and promising technology, however, is not too far off that may take additive manufacturing to a new dimension. With the recent advancement in material sciences, new approaches to additive manufacturing have also drifted to material focused operations; therefore, programable material applications with 3D printing technology revealed the term of 4D printing. As an alternative manufacturing technique, 4D printing implemented to fabricate complex forms to prove its potentials for single or mass-customized fabrications, especially in computational and generative systems. A fabrication process, including digital and physical phases, is experienced where several design disciplines are combined to generate a feasible fabrication process. For the computational form-finding process, the curved-crease folding technique utilized to create developable three-dimensional generative forms. A digital model also experimented by printing vi the active composites with different principles. Accordingly, self-transformation process of the printed active composite structures tested to prove the concept. The results show that 4D printing of curved-crease active composite structures promising to be utilized as formwork and form as it is to fabricate complex generative surface structures for single or mass-customized architectural scenarios. The fabrication experiment has also provided a source to generate a 4D printing fabrication process.

Design and construction of a six degree of freedom platform Gürbüz, Sarper; Balkan, Raif Tuna; Department of Mechanical Engineering (2006) In this thesis a six degree of freedom (DOF) parallel manipulator is designed, developed and simulated virtually. The platform, which is specified and focused on in this thesis, is the specific solution for the generating the required data to simulate a land, airborne or sea vehicle’s motion trajectory in the laboratory environment. After explaining the need for such platforms for the military industry, the existing devices will be presented and discussed. Then the design period will be explained while poin...
An intelligent design approach trained by fabrication techniques Sönmez, Ayça; Sorguç, Arzu; Department of Aerospace Engineering (2021-2-15) The developments in recent technologies through Industry 4.0 lead to the integration of digital design and manufacturing processes. While manufacturing is becoming an essential input of the design, it is usually considered at the last stages of the design process. This misconception creates a gap between digital design and fabrication, resulting in fabricated outcome being different from initial design in the context of architectural tectonics. This thesis aims to provide a basis to bridge digital design an...
Repositioning moving image in computational design education Kavakoğlu Akçay, Ayşegül; Sorguç, Arzu; Department of Architecture (2015) The boundaries between science, art and design have begun to disappear with the developments in computational technologies particularly in the 21st century. Along with this convergence via computational technologies, architecture and design adapt new design tools and methods, which affected the design process at the first glance. The circumstances of these adaptations influenced both theory and praxis in architecture and design by resulting in paradigmatic shifts in which the meaning of design tools evolved...
Extending design cognition with computer vision and generative deep learning Çakmak, Başak; Mennan, Zeynep; Department of Architecture (2022-2) This thesis proposes to scrutinize the project of extending cognition in the field of design by providing the exploration of alternative procedures of formalization. It aims at investigating the possible extensions of design cognition with a theoretical framework based on the concept of Extended Cognition, traced within two different contexts: One is the phenomenological context, which aims at a sensual and cognitive extension in the design studies of the 20th century searching for a counter-cultural expres...
Prototypes in Architectural Education: As Instruments of Integration in the Digital Era Özsel Akipek, Fulya ; Kozikoğlu, Nilüfer (Middle East Technical University, Faculty of Architecture, 2007-6-01) Architectural design and education today has a strong new focus on process, material and data organizations with the conceptual background of emergence and complexity of the digital era. In this paper, we reevaluate the design as research, and distinguish the digital and conceptual modes of prototypes in dialogue with the material prototypes. Through four instances in our current educational experience, we review this dialogue and the field of potentialities that exist in the interrelation of the different ...
