This paper presents a novel method for generating image projections required for Digital Light Processing type 3D printer systems where the entire cross-section of the printed object is directly formed via projecting the image onto a vat of photopolymers. The cross-sections (i.e. slices), which are initially represented as bitmap images, are compressed via a novel lossless compression technique which makes good use of relative data encoding. The coherence between the consecutive slices (or images) are taken into account in this proposed paradigm. The method yields satisfactory performance in terms of data compaction achieved in the test cases considered. (c) 2017 The Authors. Published by Elsevier B.V.

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 ...
A NOVEL PLANAR LAYERED REPRESENTATION FOR 3DTV AND FREEVIEW TV APPLICATIONS Ozkalayci, Burak; Alatan, Abdullah Aydın (2013-07-19) A novel planar layered representation for 3D content is proposed. The proposed representation aims to decouple the geometric and textural distortion related artifacts in novel view rendering. In this perspective, an energy minimization-based framework is utilized to fit planar models from 3D range data. The planar model assignments provide object-like segmentation of the scene. By rendering the corresponding texture information of the planar assignments, the proposed representation is finalized. In novel vi...
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...
A new design and a fabrication approach to realize a high performance three axes capacitive MEMS accelerometer Aydemir, Akin; Terzioglu, Yunus; Akın, Tayfun (2016-06-15) This paper presents a new fabrication approach and design for a three axis capacitive MEMS accelerometer that is capable of measuring externally applied accelerations in three orthogonal axes. Individual lateral and vertical axis accelerometers are fabricated in the same die on an SOI wafer which is anodically bonded to a glass substrate. Handle layer of the SOI wafer is used as the top electrode for the vertical axis accelerometer. This accelerometer has a 2 mm(2) perforated electrode area anchored to the ...
PROGRESSIVE COMPRESSION OF DIGITAL ELEVATION DATA USING MESHES Kose, Kivanc; Yılmaz, Erdal; ÇETİN, AHMET ENİS (2009-07-17) In this paper a new Digital Elevation Map (DEM) image compression algorithm is proposed. DEM image can be threated as a grayscale image, whose pixel values are the elevation values of the map points. The grayscale DEM image is compressed using an adaptive wavelet based image compression algorithm. The method, which is an extension of the progressive mesh compression takes advantage of the multiresolution property of the wavelets while coding the map images. This makes it possible to decode different resolut...
