—This paper proposes a novel approach to generate patterned indentations for different additive manufacturing methodologies. Surface textures have many practices in different fields and require special manufacturing considerations. Beside conventional manufacturing processes, additive processes have also been utilized in the last decade to obtain textured surfaces. The current design and fabrication pipeline of additive manufacturing operations have many disadvantages in terms of surface patterns. For instance, the size of the design files grow considerably when there are detailed indentations on the surfaces of the artifacts. The presented method overcomes most of these disadvantages while fabricating the objects with surface patterns. It employs Boolean operations on binary images of the slices on the hardware of the 3D printers to obtain various types of textures.

Generation of patterned indentations for additive manufacturing technologies Yaman, Ulaş; Dölen, Melik; Hoffmann, Christoph (Informa UK Limited, 2019-02-01) This article proposes a novel approach to generate patterned indentations for different additive manufacturing methodologies. Surface textures have many practical applications in various fields, but require special manufacturing considerations. In addition to conventional manufacturing processes, additive processes have also been utilized in the last decade to obtain textured surfaces. The current design and fabrication pipeline of additive manufacturing operations have many disadvantages in that respect. F...
Creating tougher interfaces via suture morphology in 3D-printed multi-material polymer composites by fused filament fabrication Altuntas, Umut; Çöker, Demirkan; Yavas, Denizhan (2023-01-05) This study presents a facile strategy for architecting the interface morphology to create tougher and stronger interfaces in additively manufactured multi-material polymer composites. A sutural interfacial morphology between two dissimilar polymer phases PLA (hard) and TPU (soft) is designed and fabricated by the fused filament fabrication technique. The proposed strategy utilizes one of the process parameters (i.e., overlap distance) to create sutural interfaces with soft protrusions. The microscopic inspe...
Development and Modeling of a Wafer-Level BCB Packaging Method for Capacitive RF MEMS Switches Comart, Ilker; Cetintepe, Cagri; Sagiroglu, Ebru; Demir, Şimşek; Akın, Tayfun (2019-08-01) This paper presents a novel wafer-level packaging method for shunt, capacitive RF MEMS switches using BCB as the adhesive interlayer. Fabrication and electrical characteristics of the proposed package were initially evaluated for 50 Omega CPW lines. Microwave measurements of these packaged test structures were fitted to a circuit model, which was later employed to optimize the package for RF MEMS switches. The proposed packaging method was next successfully integrated with an in-house RF MEMS fabrication pr...
Characterization of flow regime in concentric annuli and pipes for yield-pseudoplastic fluids Gucuyener, IH; Mehmetoglu, T (1996-09-01) This paper presents an analysis of the laminar-turbulent transition for flow of yield-pseudoplastic fluids in pipes and concentric annuli. The yield-pseudoplastic rheology is represented by the three-parameter Robertson-Stiff model, A modified Reynolds number is developed based on an equivalent diameter including characteristic parameters of the flow situations under consideration. Using the literature data, Hanks' theory of laminar flow stability is reanalyzed in comparison with other correlations. On acco...
DEVELOPMENT OF AN AUTOMATIC DESIGN AND ANALYSIS TOOL FOR AXIAL FLOW COMPRESSORS Kundes, Necmettin Anil; Aksel, Mehmet Haluk; Baran, Özgür Uğraş (2019-01-01) This paper presents a new design and analysis tool that is developed to be employed during the design process of axial flow compressors. The tool chain implemented by this design tool consists of five parts: a mean-line design tool, followed by a blade geometry parametrization tool. Then 3D blade geometry is created, next a high quality structured mesh is generated and completed by Computational Fluid Dynamics (CFD) solution. All components employed in the new tool are either new developments, or achieved b...
