摘要： A printer includes a heat control device configured to cause a temperature of a part that is printed by the printer to remain within a predetermined range as a height of the part increases from about 0 mm to about 30 mm. The predetermined range is from about 545° C. to about 600° C. The heat control device includes a heat plate that is configured to generate heat in a downward direction toward the part.

摘要： A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

摘要： A three-dimensional (3D) metal object manufacturing apparatus has a volume of thermally insulative fluid in which a X-Y translation mechanism moves to position a platform opposite an ejector head. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. The thermally insulative fluid is a molten salt, such as a molten fluoride, chloride, or nitrate molten salt. The thermally insulative layer protects the X-Y mechanism while the housing helps keep the surface temperature of the object being formed on the platform in an optimal range for bonding of melted metal drops ejected from the ejector head to a surface of a metal object being formed on the platform.

摘要： In one example, a three-dimensional (3D) printing method is disclosed. The 3D printing method may partition an entirety of a powder bed into a plurality of portions including a first portion and a second portion. The method may position an energy source over first portion of the powder bed, apply irradiation to the first portion until an irradiation dose is reached, and turn off irradiation to the first portion of the powder bed. The 3D printing method may rearrange the energy source and the powder bed to position the energy source over a second portion of the powder bed, apply irradiation to the second portion until the irradiation dose is reached, and turn off irradiation to the second portion of the powder bed.

摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

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.

摘要： A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.

摘要： A build unit for additively manufacturing three-dimensional objects may include an energy beam system having one or more irradiation devices respectively configured to direct one or more energy beams onto a region of a powder bed, and an inertization system including an irradiation chamber defining an irradiation plenum, one or more supply manifolds, and a return manifold. The one or more supply manifolds may include a downflow manifold configured to provide a downward flow of a process gas through at least a portion of the irradiation plenum defined by the irradiation chamber, and/or a crossflow manifold configured to provide a lateral flow of the process gas through at least a portion of the irradiation plenum defined by the irradiation chamber. The return manifold may evacuate or otherwise remove process gas from the irradiation plenum defined by the irradiation chamber. While irradiating the region of the powder bed, the process gas may flow through the one or more supply manifolds, into the irradiation plenum, and from the irradiation plenum into the return manifold.
