Method of manufacturing a precision micro-filter
First Claim
1. A method of manufacturing a precision micro-filter, comprising the steps of:
- micromachining a mold material to form a micro-filter mold comprising a base and a plurality of protrusions extending substantially perpendicular from said base wherein micromachining includes one of micro-electro-discharge machining, laser-beam micro-machining and electron-beam micro-machining;
introducing a liquid material into the micro-filter mold, said liquid material being a material selected from the group consisting of polymers and ceramics;
allowing the liquid material to solidify and to form the precision micro-filter; and
separating the precision micro-filter from the micro-filter mold.

Abstract
A method of manufacturing a precision micro-filter and a micro-filter manufactured thereby is disclosed. A micro-mold is manufactured using micro-machining technology (such as micro-electrical-discharge machining technology, laser-beam micro-machining, electron beam micro-machining) to make a filter mold with a plurality of rod-like protrusions, of the shape, dimensions, and spacing required for the pores of a finished micro-filter. A molding material is placed into the micro-mold, the molding composition is allowed to solidify to form a micro-filter, the passageways of which conform precisely to the rod-like protrusions of the mold. This micro-filter is then separated from the micro-mold.
