Abstract: Examples of the present disclosure relate to a method of manufacturing a container for a printing material. The method includes providing a first portion of the container comprising an opening circumscribed by an annular wall. The method then includes providing a second portion comprising an annular cavity, followed by joining the two portions by advancing the annular wall into the annular cavity by applying a compressive force in an axial direction of the opening, and temporarily rotating the first portion and the second portion relative to each other to fuse the first and second portions.

Abstract: Ink supplies are disclosed in examples herein. An example apparatus a housing includes a first chamber and a second chamber, the housing defining a first port to fluidly couple the first chamber to a printer, the housing including a second port to fluidly couple the first chamber and the second chamber to flow fluid from the second chamber to the first chamber. The apparatus also includes a regulator coupled between the first chamber and the second chamber, the regulator to flow gas from the first chamber to the second chamber when a pressure within the first chamber reaches a threshold.

Abstract: Examples of the present disclosure relate to a container. The container has a chamber for storing build material for a three-dimensional printing system. The container comprises an opening coaxial with the chamber for coupling to the three-dimensional printing system. The container is configured such that rotation of the chamber in a first direction conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction conveys the build material away from the three-dimensional printing system.

Abstract: In one example, a container for holding printing fluid includes a chamber to hold a printing fluid and an inelastic, expandable, and contractible bag occupying space in the chamber. The exterior of the bag is exposed to an interior of the chamber and an interior of the bag is sealed against the interior of the chamber and vented to the atmosphere.

Abstract: A container includes an elongate hollow reservoir and an elongate handle. The reservoir is to store a printing material and includes a closed end and an opposite openable end. The reservoir includes a first outer edge portion. The elongate handle at least partially defines the closed end and is aligned to orient at least the first outer edge portion of the reservoir for removable slidable insertion relative to, a complementary shaped, receiving portion of an element of an additive manufacturing device.

Abstract: A fluid seal may comprise an external sealing body, and an internal sealing body disposed within the external sealing body. The internal sealing body may be radially connected to the external sealing body by a webbing. Further, the external sealing body may hermetically seal a fluid path from the exterior of the fluid path, while the internal sealing body may hermetically seal the fluid path from within the interior of the fluid path.

Abstract: A system and method for operating a supply station in a three-dimensional printer are provided. The system includes a control unit, including a processor to execute modules. An install module confirms parameters of a build material container after the build material container is secured into a supply station to determine if the parameters match expected parameters. The install module releases the build material container if the parameters do not match the expected parameters.
