today radiology and imaging are the only and main method to generate geometrical data from body. 3d model of the body will give us the best and reliable information for better understanding and diagnostic. on the other hand with development of cad/cam and rapid prototyping, the 3d printers were born to build 3d models without considering the geometry. today the 3d printers are able to makes a 3...

Stereo-lithography is a distinctive form of technology which permits for the translation of computer aided design illustration to3D solid items within hours. In Stereo-lithography melted plastic is solidified in particular patterns by laser beam consequential in solid epoxy realization of a 3D project. This ultraviolet laser beam is directed by CAD data. Parts created using Stereo Lithography m...

In this paper we demonstrate that it is possible to produce low cost neutron-sensitive detectors using stereo-lithography additive manufacturing. A curable scintillating resin made by mixing BN:ZnS with a commercially available UV resin. This used print several small area neutron of arrays cones can be directly coupled photo-multiplier tube.

Abstract Photopolymerizable resins are increasingly used to generate complex 3D printed parts through stereo lithography, digital light processing (DLP) and liquid crystal display (LCD) printing. Many challenges relating the resin chemistry printing parameters still exist must be addressed in order entirely control properties of after This work reviews current knowledge describes potential DLP/...

Abstract Nano-kirigami method enables rich diversity of structural geometries that significantly broaden the functionalities optical micro/nano-devices. However, methodologies various nano-kirigami are still limited and as a result, chiral structure has yet been pushed to limit for operation at visible wavelength region. Here, merits strategies comprehensively explored bio-inspired nano-cilia m...

The triangulation of boundary representation geomet-ries (BRep geometries) is neccessary for display generation , stereo-lithography applications and also nite element mesh (FE mesh) generation. The accuracy of the tesselation is of great signiic-ance not only for stereo-lithography and rendering algorithms but also for FE mesh generation, since even minor simpliications of the geometry of the ...
