Abstract: A 3D printer is disclosed herein. The 3D printer comprises a build material distributor to generate layers of a build material in a spreading direction along a spreading axis; a resonator mounted on the build material distributor to vibrate the build material distributor along the spreading axis at a frequency; and a controller. The controller is to control the resonator to vibrate the build material distributor at the frequency while controlling the build material distributor to spread a volume of build material over a platform to generate a layer of build material.

Abstract: Examples of the present disclosure relate to a container for a three-dimensional printing system. The container has a chamber for storing a build material. The container has a base mounted within an open end of the chamber, the base having a channel structure and having at least one material-conveying structure. The chamber has an inner surface having helical raised portions to convey build material between the chamber and the at least one material-conveying structure during rotation. The at least one material-conveying structure has a radially aligned opening to receive build material conveyed by the helical raised portions in a direction perpendicular to an axis of rotation and is configured to transport the build material towards an opening of the channel structure.

Abstract: A reader mechanism and method for interfacing with an information chip on a build material container are provided. The reader mechanism includes a reading head configured to read the information chip. A platform includes an actuator to move the reading head relative to the information chip. A brake holds the build material container in place while the reading head contacts the information chip.

Abstract: Examples of the present disclosure relate to a base for a printing material container. The base has a channel structure defining an opening of the base, an axis of the channel structure defining an axial direction. The base also has a material-guiding structure, formed around the opening, having a helical lower surface that extends from the channel structure in the axial direction. An upper surface of the material-guiding structure is formed by a lower surface of the base and the helical lower surface meets the lower surface of the base at a curved side wall that extends radially from the channel structure to an annular portion of the base.

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.
