Electrochemical Printing for 2 & 3 Dimensional Rapid Fabrication

Introduction Electrochemical Fabrication is the process of manufacturing a wide array of devices by either electrodeposition of pure metal/alloys on substrates or by selectively producing and/or removing material from the substrate through the use of spatially controlled electrochemical reactions. Most conventional fabrication techniques require the use of Masks to define the shape of fabricated structures. There are several limitations to the use of this technique, such as: the initial design and production of the masks is costly, several masks are required and the precise alignment of the masks is critical, the size of the patterned feature is limited by the wavelength of light used, and the type of materials that can be fabricated is limited. Technology description Researchers at the University of Washington have developed a new Computer Aided Electrochemical Fabrication Apparatus for the manufacturing of 2- and 3- dimensional micro and larger systems. The new Electrochemical Fabrication apparatus does not require the use of masks, thus eliminating all the limitations of masks. 3-D Solid objects can be built directly from a computer image. Moreover, it can locally control the rates of mass transfer at the growth surface, allowing simultaneous fabrication of different types of materials. The diversity of possible build material types includes metals, semiconductors, polymers, ceramics and proteins. Business opportunity Fabrication of a variety of micro and larger scale systems including semiconductor devices, actuators, sensors, electro-mechanical and magneto-mechanical switches, custom electronics packaging, etc Stage of development The University seeks inquiries from parties interested in commercializing this technology or sponsoring further research in this area Intellectual property position
