The electrical Field Activated Sintering Technology (FAST) process uses low voltage and high current, pressure-assisted sintering and synthesis technique, which has been used recently in materials processing. This method can be used to densify materials and create compounds, and it is similar to hot pressing, but the mechanism of the heating and powder densification are different. In this paper an innovative methodology has been adapted from the FAST process that can decrease the volume of the components into micro scale and called (MicroFAST). This process is a rapid powder consolidation technology and shows the possibility to produce solid parts from powder material. Using MagnesiaStabilized Zirconia (MSZ) powder material, several processing parameters have been investigated, such as pressure, heating rate, heating temperature and holding time, which helped to gain optimum results. In this paper Ø4.00mm × 4.00 mm and Ø2.00mm × 2.00 mm cylinder solid samples were shaped. The SEM and EDS have been conducted and the relative density has been examined and the results showed a very good fabricated sample with 99.83% relative density.
