Abstract: A three-dimensional (3D) printer and method having a pneumatic conveyance system (PCS) to transport build material to a vessel of the 3D printer. A feeder coupled to the vessel regulates the discharge flow of build material from the vessel. A sealing control coupled to the feeder reduces air inflow.

Abstract: A 3D printer and method include a cartridge receiver to hold a material cartridge that accepts build material into the material cartridge from the 3D printer and makes build material available from the material cartridge. A first conveying system of the 3D printer transports build material for the 3D printing. A second conveying system of the 3D printer facilitates recovery of excess build material from the 3D printing.

Abstract: Examples of the present disclosure relate to a container comprising a chamber for storing a material for printing. The container has a material-guiding structure formed around a channel structure of the container, the material-guiding structure being arranged to guide the material between an interior of the container and the channel structure during rotation of the container. The chamber has a raised portion within an inner surface of the chamber to guide the material into an opening of the material-guiding structure.

Abstract: A three-dimensional (3D) printer includes a selective solidification module to selectively solidify portions of successive layers of a build material on a build platform. The 3D printer also includes a cartridge receiver to hold a removable material cartridge that accepts material from the 3D printer and makes material available to the 3D printer for printing of the 3D object.

Abstract: Example implementations relate to different mixtures of build materials deliverable during a three dimensional (3D) print operation. In some examples, a 3D print apparatus may include a delivery hopper to deliver build material to a print zone of the 3D print apparatus and a plurality of build material hoppers to which the delivery hopper is connected for receipt of at least one of a corresponding plurality of build materials. A controller of the 3D print apparatus may direct that variable proportions of a first build material relative to a second build material are receivable by the delivery hopper from the plurality of build material hoppers during the 3D print operation, where different mixtures of the variable proportions of the first build material and the second build material are deliverable to the delivery hopper during the 3D print operation.
