Projection 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...
متن کاملFabrication of Tissue Scaffolds using Projection Micro- Stereolithography
In vitro liver models are a critical tool in pharmaceutical research, yet standard hepatocyte cultures fail to capture the complexity of in vivo tissue behavior. One of the most critical features of the in vivo liver is the extensive microvasculature which allows for the delivery of nutrients and metabolites without exposing hepatocytes to de-differentiating fluidic shear stresses. A new liver ...
متن کاملA Novel Projection based Electro-Stereolithography (PES) Process for Composite Printing
Most current additive manufacturing processes can only process one material in one build. Few of them are able to fabricate multiple materials and composites, with limited choices of materials. In this research, we propose a novel Projection based Electro-Stereolithography (PES) process, which is able to fabricate composites with high resolution and fast speed, and a big range of material choic...
متن کاملFast Recoating Methods for the Projection-based Stereolithography Process in Micro- and Macro-Scales
The purpose of this paper is to present a recoating method for the development of a direct digital manufacturing (DDM) process that can be an order of magnitude faster than other currently available DDM processes. In the mask-image-projection-based Stereolithography (MIP-SL) process, projection light controlled by a Digital Micromirror Device (DMD) can quickly cure liquid photopolymer resin in ...
متن کاملDevelopment of a 3D printer using scanning projection stereolithography
We have developed a system for the rapid fabrication of low cost 3D devices and systems in the laboratory with micro-scale features yet cm-scale objects. Our system is inspired by maskless lithography, where a digital micromirror device (DMD) is used to project patterns with resolution up to 10 µm onto a layer of photoresist. Large area objects can be fabricated by stitching projected images ov...
