摘要： A build material management system for an additive manufacturing system is described in which a recovered build material tank (208) and a mixing tank (212) are provided. The recovered build material tank (208) comprises an outlet and a first build material filter (218b) for separating a gas flow from a build material flow. The mixing tank (212) comprises a second build material filter (218c). The mixing tank (212) is connected to the recovered build material tank (208) via a RBMT-to-mixer conduit (286). A controller (295) is provided to couple the second build material filter (218c) to a reduced pressure interface to transport build material from the outlet of the recovered build material tank into the mixing tank (212) via the second build material filter (218b). The controller (295) controls coupling of the first build material filter (218b) to the reduced pressure interface to transport build material from a build material source into the recovered build material tank (208). A corresponding method is provided.

摘要： A build material management system for a 3D printing system is described in which a non- fused purged build material port is to output purged non-fused build material from a build material transportation system. An emptying of substantially all non-fused build material from at least a portion of the build material transportation system to the non-fused purged build material port in response to a received purge signal is controlled by processing circuitry of the build material management system.

摘要： There is provided a 3D printing build material container (31) comprising a reinforcement structure (34), a collapsible reservoir (33) to hold build material, a build material outlet structure (313), at least one first inlet structure (314, 316), and a second inlet structure (315). The reinforcement structure encloses an airtight space and the reservoir is disposed within the reinforcement structure. The build material outlet (313) structure is to allow build material to exit the reservoir. The at least one first inlet structure (314, 316) is to allow recycled build material to enter the reservoir and to selectively allow a gas to enter the reservoir. The second inlet structure (315) is to selectively allow a gas to enter a space between the reservoir and the reinforcement structure.

摘要： An apparatus for unpacking objects built using build material in an additive manufacturing process, the apparatus comprising: an unpacking compartment; a collection hose 144 to operate within the unpacking compartment to recover by suction non-fused build material from around built objects; and a recovered build material tank (108, fig 1B) coupled to the collection hose to receive non-fused build material recovered by the collection hose; the apparatus to provision recovered non-fused build material from the recovered build material tank for an additive manufacturing process. The apparatus preferably comprises an overflow tank (110, fig 1B) which may be coupled to the collection hose and switching valves to enable fluid communication from the collection hose to the recovered material tank and the overflow tank. The apparatus preferably comprises a housing at least partially open to permit a user access to operate the collection hose; a dust filter and a compartment airflow pump create a laminar flow through the unpacking compartment and dust filter to contain powder in the apparatus. One or more built part cleaning tools may attach to the collection hose proximate a suction opening of the hose. A conduit may be provided to provide recycled build material from the recovered build material tank for provision to a build platform in an additive manufacturing process.

摘要： A container (140) for receiving a manufactured object (160) from a 3D printer is disclosed. A method for cooling and unpacking 3D printed objects using that container. (140) is also disclosed. The container has a wall forming the sides of the container, a top extending to the sides of the container, a connector (142) for connection to a vacuum source and a guillotine member (150). The lower portion of the container has support members to slidably receive the guillotine member (150) to form a base of the container. The guillotine member is selectively configurable between an apertured configuration having a plurality of through holes (152) to allow passage of air and/or build material, and a closed configuration in which the through holes are closed so as to prevent build material from falling out of the container.
