    Wafer-Scale, Solid Freeform Fabrication of Fully-Assembled Metal Micro-Mechanisms for Minimally-Invasive Medical Devices
    (University of Texas at Austin, 2009-09) Cohen, A.; Chen, R.; Frodis, U.; Wu, M.; Folk, C.
    The EFAB process was first presented at the SFF Symposium in 1998, at a very early stage of its development. Currently, the technology is able to produce complex 3-D devices— including mechanisms built pre-assembled—in production volumes, using a three-step process of selective electrodeposition of one metal, blanket electrodeposition of another metal, and planarization. Layer thickness is as small as 4 µm, minimum feature size is down to 10 µm, and linear tolerances are ~2 µm. Metals are biocompatible materials with mechanical properties similar to stainless steel. The technology enables new instruments for minimally-invasive surgical and interventional procedures.
