Solid free form fabrication techniques are commonly employed in near net shaping of ceramics
especially in the manufacture of microelectronics. Lead magnesium niobate (PMN) is an important
relaxor ferroelectric material with perovksite structure used in the production of these multilayer
ceramic devices. In this study two dimensional PMN arrays and three dimensional periodic structures
were produced by robocasting which is a direct writing technique. Aqueous colloidal gels have been
formulated for use as ink in solid freeform fabrication process. Results showed that complex PMN
shapes having rod size down to 100 μm can be successfully produced by robocasting process to be
used in microelectronic applications.
