Abstract
An apparatus for laser additive manufacturing, comprising an optical housing configured to receive a laser beam and a feedstock therein, wherein the feedstock is for use in an additive manufacturing process that includes a build plate or other additive manufacturing work surface; a first reflective optic for receiving and reflecting the laser beam; and a second reflective optic for receiving laser light reflected by the first reflective optic, wherein the second reflective includes a first region of curvature for directing a portion of the laser light received from the first reflective optic onto the feedstock in a cylindrical configuration such that the feedstock and the cylinder of laser light are coaxial with regard to one another; and a second region of curvature for directing a portion of the laser light received from the first reflective optic onto the build or surface only in a ring-shaped configuration.
