  • Publication number: 20200164437
    Abstract: Disclosed is a method for providing control data for an additive manufacturing device. The method includes accessing computer-based model data of a section of the object to be manufactured, defining a first portion and an adjoining second portion within the object section, and producing a data model of a region of a layer of the object section. Within the region a first portion cross-section cuts through the first portion and a second portion cross-section cuts through the second portion. An energy input parameter in the data model has, on average, a different value in the first portion cross-section than in the second portion cross-section and the energy beam is moved over the boundary of the first and second portion. Control data corresponding to the data model is provided for the generation of a control data set for the additive manufacturing device.

  • Publication number: 20200101666
    Abstract: A standard powder bed fusion additive manufacture apparatus is provided with a device to modify the building space, including the powder feed for the building space, yielding a reduction in the active build area, with a concomitant reduction in the adjacent powder supply. A retrofit kit or assembly which is quickly emplaced on the existing equipment with little modification of the regular building space is provided, and is therefore readily removable when the building space is to be returned to its original condition. One advantage is the relatively quick manner in which the building space can be modified. A reduced area build piston is slideably received in a shaft depending from a cover that is emplaceable on the unmodified build area. The build piston moves with the pre-existing build platform. A like arrangement is provided for the feed container.

  • Publication number: 20200101665
    Abstract: A dual roller powder spreader assembly for use in layerwise manufacture in a powder bed fusion additive manufacture process utilizes in an embodiment tilting of the dual roller assembly such that a lead roller is raised upwardly relative to the powder bed in a sweep. This is accomplished using a mechanical cam-like engagement initiated at each end of the assembly's travel, causing what will then be the lead roller to rise as a whole relative to the now following roller, the latter pushing the powder pile across the powder bed. The tilt process is reversed at each end of travel.

  • Patent number: 10583529
    Abstract: An additive manufacturing method includes providing a first and second scanners with fields of view that at least partially overlap. The method includes applying a layer of powder-based materials to the part bed and providing a number of laser sources that direct a number of laser beams to the first and second scanners. The laser beams are directed from the scanners to the part bed to selectively fuse the material to produce a layer of a three-dimensional part. The layer is formed by selectively directing laser energy to the material in a selected pattern, and synchronizing the movement of the laser beams to continuously process the selected pattern in each layer of the three-dimensional part. An additive manufacturing system includes first and second laser sources, first and second scanners, and a controller configured to operate the scanners and laser(s) for producing the three-dimensional printed part.

  • Publication number: 20200023578
