A 3D printing system comprising: a selective solidification module to: form a printed article by processing a build material; and form a printed container encompassing the printed article and a portion of unused build material about the printed article, the printed container defining a first port and a second port fluidly connected to the first port. The 3D printing system further comprises a connector to couple to the first port or second port of the printed container; and a pump fluidly connected to the connector to cause a fluid to flow through the printed container from the first port to the second port such that the printed article is cooled by the fluid flow.

A retention structure can be created using two or more different materials (e.g., one magnetic material, and one non-magnetic material) as a composite structure. The retention structure can include a cylindrical hoop comprising one or more one or magnetic regions tangentially alternating with one or more non-magnetic regions configured to surround and retain a plurality of magnets to a rotor, wherein the one or more magnetic regions are aligned with each one of the plurality of magnets and the one or more non-magnetic regions are aligned with one or more spaces between the plurality of magnets on the rotor. The magnetic material allows flux from the permanent magnets to flow through to the stators and the non-magnetic sections reduce leakage of magnetic flux to adjoining permanent magnets through use of non-magnetic materials. The retention structure can be fabricated using a hot isostatic press process.

A method of manufacturing a metal member including a first part and a second part includes a first fabrication process of fabricating the first part through a three-dimensional metal stack fabrication by a powder bed method, and a second fabrication process of fabricating an outer circumference of the second part through the three-dimensional metal stack fabrication by the powder bed method, and then sintering metallic powder remaining in an inner portion of the second part by hot isostatic pressing so as to fabricate the second part.

A method of making a capsule 2 for hot isostatic pressing (HIPing) comprises: (i) selecting a first sheet of metal; (ii) subjecting the first sheet to a forming process, for example die forming, thereby to define a first member 4a of the capsule; (iii) securing said first member to one or more other members thereby to define at least part of a capsule for HIPing.

Disclosed is a method for producing a blade for a turbomachine, which method comprises: providing a blade root, having a first platform region, from a first material; providing on the first platform region at least one capsule that is filled with a metallic and/or ceramic powder that comprises at least one second material which is different from the first material, for producing a blade airfoil having a second platform region; producing and shaping a blade airfoil from the capsule that is filled with the powder by at least one thermal input method, thereby connecting the blade root to the blade airfoil in respective platform regions.

Also disclosed is a blade which is obtainable and/or obtained by this method.

A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.
