Abstract

Free standing, micron scale, yttria stabilized zirconia parts for surgical instrument applications have been fabricated using a lithography based mold forming technique. Problems and solutions inherent to molding micron scale ceramic parts, such as suspension viscosity, surface spallation, and surface roughness are addressed. Concentrated zirconia suspensions, achieved through a chemically aided attrition milling process, are gelcast into molds via a screen printing method to form parts. After sintering, near theoretical density (99.8%) is achieved with a grain size of 500 nm.
