Abstract: There is provided a method for manufacturing a three-dimensional object including: modeling an object by extruding a material onto a stage to deposit layers; and modeling a support structure in at least a part of a support area for supporting the object. The support area includes a first support area, a second support area adjacent to the first support area, and a third support area. The manufacturing method includes: a first step of modeling a first support structure in the first support area under a first modeling condition, and modeling a second support structure in the second support area under a second modeling condition, or forming a space without extruding the material; and a second step of separating the support structure from the object. The third support area is located between the second support area and the object, and the first modeling condition and the second modeling condition are modeling conditions different from each other.

Abstract: An additive manufacturing system includes a build surface, one or more laser energy sources, and an optics assembly movable relative to the build surface. The optics assembly directs laser energy from the one or more laser energy sources toward the build surface to fuse a portion of a precursor material on the build surface. A gas head is operatively coupled to the optics assembly and movable relative to the build surface. The gas head entrains emitted materials released during fusion of the precursor material. The system also includes a gas head cleaning device having a scraper to remove debris from a surface of the gas head.

Abstract: A method and an apparatus for collecting a powdered material after a print job in powder bed fusion additive manufacturing may involve a build platform supporting a powder bed capable of tilting, inverting, and shaking to separate the powder bed substantially from the build platform in a hopper. The powdered material may be collected in a hopper for reuse in later print jobs. The powder collecting process may be automated to increase efficiency of powder bed fusion additive manufacturing.

Abstract: In one example, a 3D printing system includes a support structure generator to identify a breakaway support to temporarily support part of the object, to design a wedge shaped groove between a portion of the object and the support, the groove ending at a line along which the support intersects the object, and to generate a digital object model that includes the support and the groove. The system also includes a 3D printer to print the object, support and groove based on the object model.

Abstract: A three-dimensional shaped article production method for producing a three-dimensional shaped article by stacking layers to form a stacked body includes a constituent layer formation step of forming a constituent layer which corresponds to a constituent region of the three-dimensional shaped article, a support layer formation step of forming a support layer which is in contact with the constituent layer and supports the constituent layer, and a sintering step of sintering the constituent layer, wherein the support layer is configured such that as compared with the volume decrement accompanying the sintering step of a space surrounded by the constituent layer from at least two directions, the volume decrement accompanying the sintering step of the support layer which supports the constituent layer in the space is larger.

Abstract: The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.
