    摘要： A method of forming a metal component comprising at least one bulk volume and at least one surface layer. The method comprises: a) depositing a layer of metal powder onto a substrate; b) using a laser array to melt and fuse a first portion of the layer of metal powder; c) using one or more galvanometer mirror deflected lasers to melt and fuse a second portion of the layer of metal powder. The actions in b) and/or c) also fuses said first portion to said second portion. The second portion of the layer of metal powder is the portion which will comprise a surface layer of the finished component. The invention further includes an apparatus capable of performing the method of forming a metal component, a kit for upgrading an existing apparatus to perform the method of forming a metal component and a metal component formed from said method.

    摘要： A powder bed fusion apparatus for building an object in a layer-by-layer manner, the powder bed fusion apparatus comprising a processing chamber (101, 201, 301, 601) having a processing chamber aperture (102, 202, 302, 602, 702), a scanner (106, 206, 306, 606) arranged to direct an energy beam to locations in a plane of the processing chamber aperture (102, 202, 302, 602, 702) and a debuilding chamber (103, 203, 303, 603, 703) having a debuilding chamber aperture (104, 204, 304, 604, 704). The powder bed fusion apparatus further comprises a build chamber (118, 218, 318, 618, 718) defined by a build sleeve (119, 219, 319, 619, 719) and a build platform (120, 220, 320, 620, 720) movable within the build sleeve (119, 219, 319, 619, 719) for supporting powder within the build sleeve (119, 219, 319, 619, 719), the build platform (120, 220, 320, 620, 720) comprising a build platform seal (121) for engaging with walls of the build sleeve (119, 219, 319, 619, 719) to prevent the flow of powder past the build platform (120, 220, 320, 620, 720); and 15 at least one drive mechanism for driving movement of the build platform (120, 220, 320, 620, 720) in the build sleeve (119, 219, 319, 619, 719). A translation mechanism (125) is provided for moving the build chamber (118, 218, 318, 618, 718) between a building position, in which the build sleeve (119, 219, 319, 619, 719) aligns with the processing chamber aperture (102, 202, 302, 602, 702) such that an energy beam can be delivered by the scanner to the processing chamber aperture (102, 202, 302, 602, 702) to consolidate powder supported by the build platform (120, 220, 320, 620, 720) in the build sleeve (119, 219, 319, 619, 719) to build the object, and a debuilding position, in which the build sleeve (119, 219, 319, 619, 719) aligns with the debuilding chamber aperture (104, 204, 304, 604, 704) such that the object and powder can be inserted into the debuilding chamber (103, 203, 303, 603, 703) through the debuilding chamber aperture (104, 204, 304, 604, 704) through movement of the build platform (120, 220, 320, 620, 720) within the build sleeve (119, 219, 319, 619, 719).

    摘要： A 3D printing system uses heat sources, such as lasers, for manufacturing parts in metal additive manufacturing, such as powder-bed fusion, on one or more movable build modules. The build modules may be moved (e.g., by a conveyor system) into and out of a lasing module. Parts may be manufactured on multiple build modules simultaneously and/or sequentially, in some cases while the build module(s) are moving relative to the heat sources. Sensor(s) are arranged to determine a position, orientation, and/or movement of the build modules and feedback from the sensor(s) may be used to control the heat sources to compensate for motion of the build modules.

    摘要： A jetted binder printing system includes a carrier substrate configured to travel along a longitudinal direction thereof, an adjustable binder printer configured to deliver an adjustable binder to the carrier substrate, a dispensing module located downstream from the adjustable binder printer on the longitudinal direction of the carrier substrate, the dispensing module including at least one powder container, the dispensing module being configured to dispense powder onto the carrier substrate, and a primary binder printer located downstream from the compaction module along the longitudinal direction of the carrier substrate. The primary binder printer includes a print head configured to print a primary binder on the dispensed powder according to a desired pattern. The primary binder is printed on a surface of the powder that is opposite a surface on which the adjustable binder is printed. The primary binder is printed to match the pattern of the adjustable binder.
