Computational Modeling of Stereolithography

چکیده
— 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 this process within a high order finite element framework.

Prediction of ceramic stereolithography resin sensitivity from theory and measurement of diffusive photon transport
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...

متن کاملSmooth surface fabrication in mask projection based stereolithography
The surface finish is critical for applications such as optics, micro-fluid flow and mechanical assembly, in which optical lenses, fluidic channels and rotating components are all required to be smooth. However, the stair-stepping effect is well known in the layer-based additive manufacturing processes, in which a three-dimensional model is approximated by a set of two-dimensional layers. Conse...
متن کاملProjection micro-stereolithography using digital micro-mirror dynamic mask
We present in this paper the development of a high-resolution projection micro-stereolithography (P SL) process by using the Digital Micromirror Device (DMDTM, Texas Instruments) as a dynamic mask. This unique technology provides a parallel fabrication of complex three-dimensional (3D) microstructures used for micro electro-mechanical systems (MEMS). Based on the understanding of underlying mec...
