Abstract: In some examples, a method includes applying a negative pressure to a gas-filled volume through a vent. While a pressure in the volume decreases, the method draws a gas out through the vent and moves a liquid into the volume. The volume is filled with the liquid so that one side of the vent is covered with the liquid and the pressure in the volume increases up to a specified point.

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 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: In one implementation, a cable assistance apparatus includes a cable including a segment having a helical shape about an axis and an assist mechanism operatively connected to the cable. The assist mechanism may apply a force to adjust the segment from a first configuration to a second configuration. The first configuration may have a first span measured along the axis from a first end of the segment to a second end of the segment, and the second configuration may have a second span measured along the axis from the first end of the segment to the second end of the segment.

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: 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: A three-dimensional printing system may include a three-dimensional printer. The three-dimensional printer may include a station to receive and rotate a build material container having an axial port, an auger and at least one at least one actuator to move at least one of the build material container and the auger relative to one another to position the auger through the axial port into the build material container.
