Micromold-Based Laser Shock Embossing of Metallic Foil: Fabrication of Large-Area Three-Dimensional Microchannel Networks

摘要

Micromold-based laser shock embossing is a new three-dimensional (3D) forming technique, which utilizes laser-generated shock wave to shape the workpiece. In this article, the microchannel networks mold was produced by micro-wire electrical discharge machining (Micro-WEDM). Large-area three-dimensional microchannel networks were successfully fabricated on metallic foil surface using laser-generated shock wave. The investigation reveals that 3D microchannel networks have a high spatial resolution at the micron level. The fracture in the forming experiment was also detected. The fabrication cost is independent of the microstructures complexity. Therefore, micromold-based laser shock embossing holds promise for achieving precise, well-controlled, low-cost, high efficiency of 3D metallic microstructures.View full textDownload full textKeywordsDeformation, Embossment, Energy, Forming, Laser, Metalforming, Micromachining, MicromanufacturingRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426914.2010.532528
