APPARATUS AND METHODS FOR MANUFACTURING

摘要

An apparatus for manufacturing includes: a build chamber including a build platform; a material dispenser configured to distribute a layer of powdered material over the build platform; a mirror arranged over the build platform and defining a mirrored planar surface; a first laser output optic configured to output a first energy beam toward the mirror; a second laser output optic adjacent the first laser output optic and configured to output a second energy beam toward the mirror; a first actuator configured to maneuver the first laser output optic and the second laser output optic relative to the build platform; a lens arranged between the mirror and the build platform; and a second actuator configured to maneuver the mirror to scan the first and second energy beams across the lens, the lens outputting the first energy beam and the second energy beam toward and substantially normal to the build platform.

1. An apparatus for manufacturing, comprising:
a build chamber comprising a build platform; a material dispenser configured to distribute a layer of powdered material over the build platform; a mirror arranged over the build platform, defining a mirrored planar surface, and isolated from an environment within the build chamber!; a first laser output optic configured to output a first energy beam toward the mirror; a second laser output optic adjacent the first laser output optic and configured to output a second energy beam toward the mirror; a first actuator configured to maneuver the first laser output optic and the second laser output optic relative to the build platform; a lens arranged between the mirror and the build platform; and a second actuator configured to maneuver the mirror to scan the first energy beam and the second energy beam across the lens, the lens outputting the first energy beam and the second energy beam toward and substantially normal to the build platform.
