Three-dimensional Microcasting

Abstract

Investigations on the methods of fabricating and casting microsized parts were carried out. Alumina powder with an average diameter of 0.7 mum was dispersed in a self-hardening liquid binder, and the powder density was increased by applying centrifugal force to fabricate a cast with good shape replicability and high strength. By setting the burning temperature below 800degreesC, casting with self-destruction ability can be accomplished. The three-dimensional microshape of an ant could be fabricated.
