摘要： 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.

摘要： This shaping apparatus is equipped with: a movement system which moves a target surface; a measurement system for acquiring position information of the target surface in a state movable by the movement system, a beam shaping system that has a beam irradiation section and a material processing section which supplies a shaping material irradiated by a beam from beam irradiation section; and a controller. On the basis of 3D data of a three-dimensional shaped object to be formed on a target surface and position information of the target surface acquired using the measurement system, the controller controls the movement system and the beam shaping system such that a target portion on the target surface is shaped by supplying the shaping material while moving the target surface and the beam from beam irradiation section relative to each other.

摘要： A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

摘要： Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.

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.
