Manufacturing and characterization of uniformly porous and graded porous polymeric structures via selective laser sintering
Jande, Yusufu Abeid Chande; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2009)
Selective laser sintering is a rapid prototyping method (RP), which was originally developed, along with other RP methods, to speed up the prototyping stage of product design. The sole needed input for production being the solid model of the part, the mold/tool-free production characteristics and the geometric part complexity that can be achieved due to layer-by-layer production have extended the applicability/research areas of these methods beyond prototyping towards new applications and material developme...
Mechanical characterization and modelling of porous polymeric materials manufactured by selective laser sintering
Tekin, Cevdet Murat; Dağ, Serkan; Department of Mechanical Engineering (2009)
Rapid prototyping methods embrace a family of manufacturing methods that are developed to speed up the prototyping stage of product design. The sole needed input for production being the solid model of the part, mold/tool-free production characteristics and the geometric part complexity that can be achieved due to layer-by-layer production have extended the applicability/research areas of these methods beyond prototyping. Local pore formation in part that occurs as a result of the discrete manufacturing nat...
Effect of production parameters on porosity and hole properties in laser sintering rapid prototyping process
İlkgün, Özkan; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2005)
Selective laser sintering (SLS) is a rapid prototyping method in which three-dimensional objects are constructed by sintering thin layers of a variety of powdered materials via laser beam. In SLS, as in most other Rapid Prototyping methods, the produced parts exhibit varying degrees of intrinsic porosity due to the discrete nature of layer-by-layer production. Selective scanning and discrete bonding of individual particles or clusters of particles impart local porosity, which is mostly an undesired trait as...
Automated 3D solid FEM generator of complex structures using laser scan data
Sharei, Maha O. M.; Türer, Ahmet; Department of Civil Engineering (2019)
For newly designed buildings, 3D modeling has become an integral part of analysis and design procedure using several simplified approaches by recognized and available software; in which user manually defines the geometry, loads, material properties, and support conditions of structures. Nevertheless, geometry modeling for historical complex structures, especially for masonry type construction, wall thicknesses, openings, section losses are difficult to be accurately defined in analysis programs. Changing wa...
