US 2008/0075618 A1 · Metal Powder Layered Apparatus for Downhole Use

Abstract

A method for manufacturing a downhole tool includes obtaining a three-dimensional model of the downhole tool; converting the three-dimensional model of the downhole tool into a model having a plurality of two-dimensional layers; and building the downhole tool, layer-by-layer, by melting a metal powder or an alloy powder using an electron beam based on the model having a plurality of two-dimensional layers. A downhole tool manufactured by a process includes obtaining a three-dimensional model of the downhole tool; converting the three-dimensional model of the downhole tool into a model having a plurality of two-dimensional layers; and building the downhole tool, layer-by-layer, by melting a metal powder or an alloy powder using an electron beam based on the model having a plurality of two-dimensional layers.
