Abstract
Disclosed embodiments relate to additive manufacturing systems. In some embodiments, an additive manufacturing system includes a fixed build plate, and a build volume extends above the fixed build plate. A boundary of the build volume may be defined by a powder containing shroud that is vertically displaceable relative to the fixed build plate. A powder deposition system is configured to deposit a powder layer along an upper surface of the build volume and the powder deposition is vertically displaceable relative to the fixed build plate. An optics assembly configured to direct laser energy from one or more laser energy sources towards the build volume, and exposure of the powder layer to the laser energy melts at least a portion of the powder layer. In some embodiments, the build plate may be supported by support columns configured to maintain the build plate in a level orientation throughout a build process.
