    Abstract: An example three-dimensional printer includes a humidity source, a build material reservoir, a conduit between the humidity source and the build material reservoir, an air source to transfer air from the humidity source through the conduit towards the build material reservoir, and a valve assembly connected to the conduit to control a flow of the air in the conduit while the printer enters an inactive mode of operation. The air source is to remain in an active mode of operation. The air source is controlled to transmit the air in the conduit until the air in the conduit adjacent to the build material reservoir reaches a temperature and relative humidity threshold.

    Abstract: In an example, a scanning system includes a scanner device, a first bias member, and a second bias member. The example first bias member is able to apply pressure on a medium towards a scan surface of the scanner device (e.g., apply pressure at a scan zone defined by the boundaries of the scanner device) and the example second bias member is able to orient the medium towards the scan surface before the medium reaches the first bias member.

    Abstract translation: 在一个示例中，扫描系统包括扫描仪装置，第一偏压构件和第二偏压构件。 示例性第一偏压构件能够朝向扫描仪装置的扫描表面施加压力在介质上（例如，在由扫描仪装置的边界限定的扫描区域处施加压力），并且示例性第二偏压构件能够将 介质到达第一偏压件之前朝向扫描表面的介质。

    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: An off-axis printhead assembly includes a printhead body that has an engagement element removably attachable to an attachment mechanism of a carriage of a printing system, the attachment mechanism of the carriage removably attachable to an on-axis printhead assembly. A fluid conduit interconnect is removably attached to the printhead body, the fluid conduit interconnect to connect to a fluid conduit to communicate printing fluid from at least one off-axis printing fluid supply through the fluid conduit interconnect to the printhead body.
