As we move towards micron-scale rapid manufacturing, it is critical to understand build resolution of Stereolithography technology. In order to determine the resolution limitations, positive and negative features on Stereolithography parts were built and analyzed. Results from several experiments were compared to an analytical model and important resolution issues are highlighted. Based on thes...

Additive Manufacturing (AM) technologies build near-net shape components one layer at a time using data from 3D CAD models. AM technologies are the result of evolution of work in 3D printing and stereolithography (the STL files used to convert 3D CAD to layers for building parts come from stereolithography terminology) and could revolutionize many sectors of U.S. manufacturing by reducing compo...

— Stereolithography (STL) is an additive manufacturing process which employs an ultraviolet curable photopolymer resin to form an object layer by layer. Due to the complicated multi-physical nature of the process, the major challenge that arises is the accuracy of the finished parts. The aim of the student-research project was to gain insight into the main governing effects of STL and to model ...

A general, quantitative relationship between the photon-transport mean free path l* and resin sensitivity DP in multiple-scattering alumina/monomer suspensions formulated for ceramic stereolithography is presented and experimentally demonstrated. A Mie-theory-based computational method with structure factor contributions to determine l* was developed. Planar-source diffuse transmittance experim...

Stereolithography-based additive manufacturing of ceramics has received tremendous attention in academic and industrial communities. In order to fabricate silicon carbide (SiC) components with complex shapes by stereolithography, a high SiC loaded ceramic slurry low viscosity excellent curing ability is required. However, it challenging meet these requirements. this work, the effects resin form...

PURPOSE The purpose of this study is to compare single and three-unit metal frameworks that are produced by micro-stereolithography. MATERIALS AND METHODS Silicone impressions of a selected molar and a premolar were used to make master abutments that were scanned into a stereolithography file. The file was processed with computer aided design software to create single and three-unit designs f...

The automotive industry is of key importance in all European countries, in the USA, and in Japan. In order to fulfill the technical and economic requirements of future cars, a consequent utilization of technological developments is necessary. Of paramount importance are miniaturization technologies for sensors, microelectronics and their integration into microsystems. At the moment, a micro fab...

Bioprinting is a rapidly developing technique for biofabrication. Because of its high resolution and the ability to print living cells, bioprinting has been widely used in artificial tissue and organ generation as well as microscale living cell deposition. In this paper, we present a low-cost stereolithography-based bioprinting system that uses visible light crosslinkable bioinks. This low-cost...
