摘要： Systems and methods for multiple beam additive manufacturing use multiple beams of light (e.g., laser light) simultaneously to expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure. The light may be generated from selected light sources and coupled into an array of optical fibers having output ends arranged in an optical head such that the multiple beams are directed by the optical head to different locations on each of the powder layers. The multiple beams may provide distributed exposures forming a distributed exposure pattern including beam spots that are spaced sufficiently to separate the fused regions formed by each exposure. The multiple beams may be moved using various techniques (e.g., by moving the optical head) and according to various scan patterns such that a plurality of multiple beam distributed exposures form each build layer.

摘要： A modular laser processing enclosure includes an enclosure housing defining a laser processing area. The enclosure housing includes a top defining a top laser processing access opening providing access to the laser processing area and at least two sides defining side laser processing access openings providing access to the laser processing area. The side laser processing access openings may be located proximate the top of the enclosure housing. The enclosure may further include at least one plate configured to cover any one of the laser processing access openings. Optionally, at least one laser processing head may be configured to be mounted to any one of the laser processing access openings and/or a least one part handling mechanism may be provided to access the laser processing area through any one of the laser processing access openings for delivering parts to and/or from the laser processing area.

摘要： Systems and methods for multiple beam additive manufacturing use multiple beams of light (e.g., laser light) to expose layers of powder material in selected regions until the powder material fuses to form voxels, which form build layers of a three-dimensional structure. The light may be generated from selected light sources and coupled into an array of optical fibers having output ends arranged in an optical head in at least one line such that multiple beams are sequentially directed by the optical head to the same powder region providing multiple beam sequential exposures (e.g., with pre-heating, melting and controlled cool down) to fuse the powder region. The multiple sequential beams may be moved using various techniques (e.g., by moving the optical head) and according to various scan patterns such that a plurality of fused regions form each build layer.
