Our goal was to develop a system that would allow us to recreate live patient arterial pathology by using an industrial technique known as stereolithography (or rapid prototyping). In industry, drawings rendered into dicom files can be exported to a computer programmed to drive various industrial tools. Those tools then make a 3D structure shown by the original drawings. We manipulated CT scan ...

Stereolithography that uses a femtosecond laser was employed as a method for multiphoton-sensitized polymerization. We studied the stereolithography method, which produces duplicate solid shapes corresponding to the trajectory of the laser focus point and can be used to build a three-dimensional (3D) structure using a conductive polymer. To achieve this, we first considered a suitable polymeriz...

Purpose – The purpose of this paper is to present a mask-image-projection-based Stereolithography process that can combine two base materials with various concentrations and structures to produce a solid object with desired material characteristics. Stereolithography is an additive manufacturing process in which liquid photopolymer resin is cross-linked and converted to solid. The fabrication o...

INTRODUCTION AND OBJECTIVES The high variability of sinonasal anatomy requires the best knowledge of its three-dimensional (3D) conformation to perform surgery more safely and efficiently. The aim of the study was to validate the utility of Osirix® and stereolithography in improving endoscopic sinonasal surgery planning. METHODS Osirix® was used as a viewer and Digital Imaging and Communicati...

A sensor system for inspecting the layer surface quality in stereolithography process is proposed in this paper. Since stereolithography process builds 3-dimensional shape by forming layers repeatedly, it is very important to process each layer of stereolithography process products in some favored conditions: Every layer should be cured uniformly and hardly enough so that the adjacent two layer...

Abstract. With the use of stereolithography, one most widespread and old rapid prototyping techniques, it is possible to reproduce objects, damaged or missing parts, faithful replicas interest in field Cultural Heritage. In this work, some applications stereolithography technique replicate objects parts artistic cultural interest, are illustrated. The aim Authors highlight potential, advantages...

Three-dimensional printingand stereolithographyof functionalmaterials fornanofabricationhave recentlygenerated a big amount of interest, as have responsivematerials. We have investigated the applicability of the redox-responsive polymer poly(ferrocenylsilane) (PFS) for stereolithography purposes. Three types of PFS were synthesized, each functionalized with specific properties to make them inte...

The 3D internal structure microscopy (3D-ISM) was applied to the equine ovary, which possesses peculiar structural characteristics. Stereolithography was applied to make a life-sized model by means of data obtained from 3D-ISM. Images from serially sliced surfaces contributed to a successful 3D reconstruction of the equine ovary. Photopolymerized resin models of equine ovaries produced by stere...
