We report on 3D printing of artifacts with a structured, inhomogeneous interior. The interior is decomposed into cells defined by a 3D Voronoi diagram and their sites. When printing such objects, most slices the printer deposits are topologically the same and change only locally in the interior. The slicing algorithm capitalizes on this coherence and minimizes print head moves that do not deposit material. This approach has been implemented on a client/server architecture that computes the slices on the geometry side. The slices are printed by fused deposition, and are communicated upon demand.

Extracting auxetic patterns from meshes for 3d printing Mert, Mehmet Levend; Sahillioğlu, Yusuf; Yaman, Ulaş; Department of Computer Engineering (2018) 3D printing is a manufacturing process which generates a physical, three-dimensional object from a digital design. In our day, there exist lots of devices, called 3D printers, having different working principles and using various materials for this manufacturing process. A model designed digitally can be transformed into a three-dimensional object in the real world by 3D printers. The elasticity of objects created by 3D printers depends on the materials used during manufacturing and the digital designs. If ...
Realization of multiband microwave metamaterials fabricated via low-cost inkjet printing İbili, Hande; Keles, Selen; Eris, Ozgur; Ergül, Özgür Salih (2019-05-01) We present design and computational analysis of multiband metamaterial structures that are fabricated via low-cost inkjet printing. In particular, three-dimensional arrangements of split-ring resonators with different sizes are considered to achieve bandstop characteristics at multiple frequencies. A fast and accurate solver is employed to analyze alternative arrangements, while considering different parameters to obtain strong resonances at desired frequencies. The obtained designs are fabricated in a low-...
Dimensional accuracy improvement of fused filament fabrication holes utilizing modified interior Sımsek, Seyda; Yaman, Ulaş (2016-11-16) This paper proposes an alternative approach to improve the dimensional accuracy of the holes manufactured with Fused Filament Fabrication desktop 3D printers. As opposed to the state of the art techniques, where they scale the input geometric designs according to their predictive and statistical models, the proposed method modifies the interior of the artifacts with respect to the geometric properties of them to compensate for the shrinkages of the holes. That is, the shrinkage itself is utilized to elimina...
Off-line nominal path generation of 6-DoF robotic manipulator for edge finishing and inspection processes Nemer, Mahmoud; Konukseven, Erhan İlhan (Springer Science and Business Media LLC, 2018-10-01) This paper deals with the development of a Computer-Aided Robotic Machining Process Planning package based on SolidWorks. The main aim of the package is to generate an efficient, collision-free, nominal tool path needed for edge finishing and inspection by utilizing a 6-DoF robotic arm. The overall nominal tool path involves analyzing the geometry of the workpiece, determining and designing an efficient collision-free tool path and finally generating the tool path data for the robot and verifying it. This p...
Tuning the Center of Gravity of 3D Printed Artifacts KELEŞ, Mert; Yaman, Ulaş (Elsevier BV; 2018-06-14) In this study, we propose an Algorithms-Aided Design (AAD) approach to shift the center of gravity of 3D printed artifacts to a predefined location by creating a heterogeneous internal structure utilizing the same type of material. When the conventional design and fabrication pipeline of 3D printers and additive manufacturing machinery is employed, information about the interior of the artifacts is lost during the conversion of the design files to the STL file format. This de facto file standard only stores...
