Abstract
A method and apparatus for additive manufacturing is provided whereby a curtain of powder is provided adjacent a vertically oriented build plate, and a laser melts or sinters the powder over a region of the build plate. The curtain of powder is moved relative to the build plate to maintain the same distance between the curtain and the previously deposited layer, and the process repeated to provide a three dimensional structure on the build plate.
