Disclosed is a method for unpacking a component 11, produced by means of an additive manufacturing process, from a particulate material fill 9 of loose, unconsolidated particulate material, which is arranged together with the component 11 in a construction space 5 and surrounds the component 11. In order to unpack the component 11, the particulate material fill 9 surrounding the component 11 is transferred into a fluidized bed, so that the loose, unconsolidated particulate material is fluidized, and the fluidized, unconsolidated particulate material is drained downward off the construction space 5. In addition, a device for use in the method is described.

A supply station for dispensing build material from a build material container is provided. The supply station includes a stationary support structure supporting a cylindrical cage along an axis, wherein the cylindrical cage is configured to be rotated in a first angular direction to dispense build material from the build material container.

A carrier gas recovery system for use in cold spray manufacturing recovers carrier gas utilized during the cold spray process and recycles the carrier gas for immediate use or stores the carrier gas for future use. The carrier gas recovery system includes an enclosure subsystem, a filtration subsystem, a reclamation subsystem, and a compensation subsystem. An article is placed in the enclosure and particulate matter is carried to the article on a carrier gas stream. Carrier gas in the enclosure is filtered through the filtration subsystem to remove particulate from the carrier gas, and the filtered carrier gas is fed to the reclamation subsystem. The carrier gas either flows to a gas separator, to increase the concentration of carrier gas, or to the compensation subsystem if the carrier gas concentration is sufficiently high. The carrier gas can be stored in the compensation subsystem or used in further cold spray manufacturing.

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.

A method of manufacturing a series of objects is disclosed. In the method, a layer of a manufacturing medium is provided. Portions of the layer of the medium are bound together at at least edge regions of the layer to form a support portion. The support portion is lowered while gripping the support portion by the edge regions of the layer. A further layer of the medium is provided supported by the support portion. Portions of the further layer of the medium are selectively bound to form at least an object portion. An apparatus for performing the method is also disclosed.

Examples provide a build material management station (106). The station comprises: a processing unit which comprises a first conduit (150a, 150b, 152a, 152b) and at least one pump for pumping build material through the first conduit; and at least one external build material storage tank (110, 114a, 114b). The processing unit further comprises at least a first port and a second port (154a, 154b), both ports being located on the exterior of the processing unit such that the external build material storage tank can be connected to the first conduit through the first port and the external build material storage tank can be connected to the first conduit through the second port
