Abstract: Examples of the present disclosure relate to a container for storing a material for a printing system. The container has a channel structure for conveying the material, the channel structure providing an opening of the container and an axis of the channel structure defining an axial direction. The container also has a valve structure disposed within the channel structure. The valve structure is translatable within the channel structure between a proximal position and a distal position in the axial direction. The valve structure is non-rotatable relative to the channel structure about the axis of the channel structure. The valve structure is arranged to seal the channel structure when the valve structure is in the proximal position.

Abstract: A supply container includes a housing and a pocket on to the housing to receive a chip. The supply container also includes an alignment component on the housing to align the pocket with a chip access device.

Abstract: A horizontal interface for a fluid supply cartridge is to connect the fluid supply cartridge to a fluid-ejection device. The horizontal interface includes one or more fluidic interconnect septums to horizontally fluidically interconnect a supply of fluid of the fluid supply cartridge to the fluid-ejection device. The horizontal interface includes an electrical interface to horizontally conductively connect a digital fluid level sensor of the fluid supply cartridge to a corresponding electrical interface of the fluid-ejection device.

Abstract: A vertical interface for a fluid supply cartridge is to connect the fluid supply cartridge to a fluid-ejection device. The vertical interface includes one or more fluidic interconnect septums to vertically fluidically interconnect a supply of fluid of the fluid supply cartridge to the fluid-ejection device. The vertical interface includes an electrical interface to vertically conductively connect a digital fluid level sensor of the fluid supply cartridge to a corresponding electrical interface of the fluid-ejection device.

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.

Abstract: A three-dimensional (3D) printer material cartridge for a 3D printer includes an indicator disposed on an exterior surface of the 3D printer material cartridge. The indicator colorant is responsive to energy from an energy source of the 3D printer. The indicator is a message that becomes visible in response to exposure of the colorant to the energy.

Abstract: A three-dimensional (3D) printer includes a cartridge receiver to receive a material cartridge containing new material for generation of a 3D object. The 3D printer also includes an energy source disposed to expose an indicator on the material cartridge to energy in response to depletion of the new material in the material cartridge to change the appearance of the indicator. The changed appearance of the indicator indicates that the material cartridge no longer contains new material.

Abstract: Examples of the present disclosure relate to a container for storing a material for a printing system. The container has a channel structure for conveying the material, the channel structure providing an opening of the container and an axis of the channel structure defining an axial direction. The container also has a valve structure disposed within the channel structure. The valve structure is translatable within the channel structure between a proximal position and a distal position in the axial direction. The valve structure is non-rotatable relative to the channel structure about the axis of the channel structure. The valve structure is arranged to seal the channel structure when the valve structure is in the proximal position.

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: Examples of the present disclosure relate to a container for storing a material for printing. The container has a generally cylindrical chamber formed by a container wall, the chamber having an opening at one end. The container has an inner structure to convey the material between an interior of the chamber and the opening during rotation of the container. The container wall has an outer surface having a planar portion to align the container upon a resting surface.

Abstract: A container comprises a shell including a main portion to store a printing material for a 3D printer. The shell includes an openable end and an opposite close end. The closed end includes an end wall of the main portion and includes a hollow handle portion spaced apart from the end wall. The hollow handle portion is in fluid communication with the main portion.

Abstract: Example systems relate to a hydrophobic material vent plug for a build material container. In one example, a vent plug can include a hydrophobic material that includes a one or more pores to allow a gas to travel from a first end of the vent plug to a second end of the vent plug, and the hydrophobic material to repel liquid from the one or more of pores.

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: Example systems relate to build material containers. In one example, a build material container can include an aperture defined by an external wall of the build material container, a supply latch member located within the aperture defined by the external wall of the build material container, a shrink wrap material covering the external wall of the build material container, and a structurally weaker portion of the shrink wrap material aligned around the aperture.

Abstract: A supply container includes a housing and a pocket on to the housing to receive a chip. The supply container also includes an alignment component on the housing to align the pocket with a chip access device.
