A complex-shaped part was successfully fabricated by Laminate Object Manufacturing (LOM) technique using silicon nitride tape with aligned silicon nitride whisker seeds. The ceramic tape was cut using a commercial cutting plotter according to the cross section drafts generated by slicing a 3-D model, and then the tapes were stacked sequentially. In order to improve adhesion between the tapes, stacking was performed under vacuum. After binder burnout, the part was encapsulated using latex emulsion and was cold isostaically pressed under 250 ㎫. It was sintered to 98.5% TD at 2148 K for 4 h under 2 ㎫ nitrogen pressure.
