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: According to one aspect, there is provided a method of adding build material to a rotatable 3D printing build material container having an internal build material storage reservoir, the method comprising: providing a supply of build material to an input port of the container; rotating the container about its rotation axis at a first speed sufficient to cause build material within the container to be centrifugally forced against the outside of the internal storage reservoir.

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: 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: Embodiments of the disclosure are directed to a harness assembly including a substrate having a plurality of vias, and a trace formed atop the substrate, the trace extending between each of the plurality of vias. The harness assembly may further include a surface mounted device disposed within a via of the plurality of vias.

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: This invention relates to an apparatus and method for creating heighted competition amongst prospective buyers of an item on an online auction system. The method generally involves suspending an auction immediately upon receipt of a bid equal to or exceeding a minimum reserve price. During the suspension, notifications are sent to a closed group of potential bidders, the notifications including the amount of the bid that triggered the suspension, along with a limited duration and a resume time for a second, “bidding war” segment of the auction.

Abstract: A refrigeration appliance including a frame defining a refrigeration compartment, a door connected to the frame and having a door gasket with a magnet disposed therein, the door movable between an open position in which the refrigeration compartment is accessible and a closed position in which the door covers the refrigeration compartment, and a tunneling magnetoresistance (TMR) door sensor disposed within the frame, wherein the magnet is positioned adjacent the TMR door sensor when the door is in the closed position.

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: 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 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: Systems, devices, and methods for configurable sensor arrays are provided. An example of a configurable sensor array includes a plurality of sensors in a matrix array formed on a single backplane and a plurality of elements within one of the plurality of sensors, where the plurality of elements provides alternative electrical paths enabling the one of the plurality of sensors to have a range of output impedances.

Abstract: A method and system for distributing digital media by creating and presenting optical machine-readable data representation (OMDR) objects. Artists input digital media and associated data into an internet-based computer application storing data on a media system server. Once OMDR objects are created and displayed, users may acquire digital media via the optical recognition functions of a mobile computer application installed on a mobile device. Once the OMDR object is scanned, the mobile application communicates with a media system server configured to store, organize, validate and distribute digital media and associated data. This method allows artists, content-owners and their agents to distribute content digitally via OMDR objects instead of utility-focused distribution methods such as CDs, DVDs, books, online download or streaming subscription vendors.

Abstract: Embodiments disclosed herein relate to a filter (100). In one embodiment, the filter includes a pattern (120). The pattern may reflect or fluoresce non-visible light.
