The development of the Digital Micromirror Device (DMD) by Texas Instruments has made a significant breakthrough in 3D micro-manufacturing, and in particular, in the area of additive layer-based manufacturing. One area of particular interest for using DMD technology is microstereolithography; a technology that builds 3D shapes through successive photopolymerization of individual thin 2D layers that are stacked vertically. A DMD-based projection microstereolithography system and a robust micro-manufacturing process have been developed. This system and various micro-fabricated 3D structures with features on the order of 10 microns, including recent advancements in multimaterial micro-fabrication, will be presented and described.
