Abstract: A drawer defines a chamber to receive a media sheet from a system. A moving element is to engage the media sheet as the media sheet is output from the system. The moving element is to slide the media sheet to a target position in the drawer, and the moving element is to disengage from the media sheet once the particular media sheet has reached the target position. A retaining element is to engage the media sheet as the media sheet slides into the drawer.

Abstract: In an example, a method includes generating a plurality of calibration objects, each in a different region of a fabrication chamber of an additive manufacturing apparatus. In some examples the method further includes obtaining a measurement of a physical property of each calibration object. The method may include determining, by processing circuitry, calibrated print agent coverage amounts for each region based on the measured physical properties of the calibration objects wherein the calibrated print agent coverage amounts are to be used in a subsequent object generation operation.

Abstract: A method of three-dimensional (3D) printing is provided. Print data is received, which defines patterns of at least one agent to be applied to a layer of build material. These patterns are at least partially based on a 3D model of at least one object to be generated. The print data is processed to determine regions which are distant from said patterns. The print data is modified to add a further pattern of a detailing agent to be selectively applied to the layer of build material to generate fracture regions in a processed volume of build material.

Abstract: There is disclosed a method of cooling a bed of build material 12, 14 generated by additive manufacture. A container 10 containing a bed of build material may be provided, the bed having a hot region relative to ambient temperature. The container may be vibrated to fluidize unfused build material 12 in the container so as to cause convection of the unfused build material to cool the hot region. There is also disclosed a method of cooling a bed of build material 12, 14 including vibration when the temperature of a hot region in the bed of build material is higher than an unpacking threshold. There is also disclosed a cooling apparatus for cooling a bed of build material by vibration.
