Abstract
Powder injection molding PIM is well established in macro molding Scaling down to microPIM μPIM opens a new arena for cost effective production of micro components One potential application is the manufacture of cutting tools with sharp edges for machining However scaling down to such a level produces challenges in raw material preparation injection molding and thermal treatment In this report near dense 98 of theoretical density tensile bars and 3 mm micro gears were produced using 50 nm Yttria Tetragonal Zirconia Polycrystal YTZP The sintered gear teeth were well defined and visually defect free
