The application of miniaturized products is slowly increasing due to their demand in micro feature-based systems, which needs multitude of functions to be integrated. Several lithographic-based technologies are used to manufacture high-aspect ratio micro features, which has limitations to produce 3D features. Electro-discharge deposition (EDD) is a newly developing nonlithographic additive manufacturing process to produce micro products. The potential of this process is that any material which is conductive in nature can be made to deposit over the substrate. In the present paper, the use of magnetic field in EDD process has been investigated. It is observed from the results that height and weight of deposition are increased significantly by using magnetic field and at the same time width is reduced due to plasma confinement by magnetic field effects. From the scanning electronic microscope (SEM) images it is observed that there is uniformity in deposition of the tool material over the substrate. It is concluded from the experimental results that, magnetic field is also a one of the significant contributing parameter assisting in electro-discharge deposition process. © 2014, Springer-Verlag London.
