Parts for microelectromechanical systems often need to be three dimensional (3D) and have sizes in the micrometer range. A novel method is described for the convenient fabrication of such 3D microstructures by means of microcontact printing, electrodeposition, and removal of the substrate. The technique is illustrated with the fabrication of structures with the form required for coronary stents (see Figure).
