POWERED REMOVAL FOR ELEMENT FORMED BY ELECTRON BEAM MELTING

摘要

A method for forming a part (100). The method includes: forming a first portion (102) of the part at a first level; forming a second portion (104) of the part at a second level; wherein forming the first and second portions includes exposing the first and second levels to a sintering process and portions of the first and second levels to an electron beam; forming a wire (110) in a passage (106) formed inside the first and second portions (102, 104) by exposing a portion of the passage (106) to the electron beam; applying a signal to the wire (110) to break up sintered material in the passage (106); and removing the wire (110).
