Abstract: Aspects described herein relate to additive manufacturing systems and related methods. An additive manufacturing system may include two or more laser energy sources and associated optical fibers. An optics assembly may be constructed and arranged to form a rectangular laser energy pixel associated with each laser energy source. Each pixel may have a substantially uniform power density, and the pixels may be arranged to form a linear array of laser energy pixels on a build surface with no spacing between the pixels. Exposure of a portion of a layer of material on the build surface to the linear array of laser energy pixels may melt the portion of the layer.

Abstract: Disclosed embodiments relate to recoater systems for use with additive manufacturing systems. A recoater assembly may be adjustable along multiple degrees of freedom relative to a build surface, which may allow for adjustment of a spacing between the recoater assembly and the build surface and/or an orientation of the recoater assembly relative to an orientation of the build surface. In some embodiments, the recoater assembly may be supported by four support columns extending above the build surface, and attachments between the recoater assembly and the support columns may be independently adjustable to adjust the recoater relative to the build surface.

Abstract: Laser control systems and related methods for controlling arrays of lasers are disclosed. A laser control system may include a first controller configured to generate a trigger signal based on a position of a laser array, and a second controller configured to send a firing signal to one or more lasers of the laser array upon receiving the trigger signal. The one or more lasers may be selected based on a desired pattern of laser energy to be formed at a particular position of the laser array.

The gas flow head includes a gas inflow through which a supply gas flows into the gas flow head, a gas outflow through which a return gas flows out of the gas flow head, and an aperture arranged to permit transmission of the laser energy through the gas flow head to the build surface. The supply gas and return gas define a gas flow profile within the gas flow head.
