    Abstract: According to examples, a system may include a first carriage carrying a laying device that may form a build material layer over a build area and a first energy source that may apply energy onto the build material layer as the first carriage is moved over the build material layer. The system may also include a second carriage carrying an agent delivery device and a second energy source, in which the agent delivery device may selectively deliver an agent onto the layer of build material and the second energy source may apply energy onto the agent and the layer of build material as the second carriage is moved across the build material layer. The system may further include a controller to control movement of the first carriage and the second carriage across the build area, in which the first carriage may be independently movable with respect to the second carriage.

    Abstract: In one example method, a determination is made via a processor that a document is to be printed using a printer including a printhead assembly and a printhead accessory based on a received print job. A determination is made via the processor that a first portion of the document is to be printed by the printhead assembly and a second portion is to be printed by the printhead accessory based on a characteristic of the printhead accessory. The first portion of the document is printed via the printhead assembly and the second portion of the document is printed via the printhead accessory.

    Abstract: Example systems relate to recoater movement. A non-transitory machine readable medium may contain instructions executable by a processor. The instructions may include instructions to change an action of a recoater in response to a determination that the recoater has reached a first location of a build area comprising build material. Instructions may further include instructions to lift the recoater in response to a determination that the recoater has reached a second location of the build area. Instructions may additionally include instructions to move the recoater over the second location at the lifted position, wherein the second location includes a build-up of the build material.

    Abstract: A 3D printer includes a movable platform, a motor to vertically translate the movable platform during an additive manufacturing process executed by the 3D printer to form a product on the movable platform, a linear encoder strip attached to the movable platform and a linear encoder reader disposed to read the linear encoder strip as the linear encoder strip moves relative to the linear encoder reader. A control circuit is to drive the motor based on an output of the linear encoder reader.

    Abstract: In one example, a media feed system includes a pick arm that is adjustable at a pivot and operable to maintain a distance between a pick roller and a separation wall as the pick arm changes orientation. In another example, a media feed system may include a pick arm, a pick roller coupled to the pick arm, a pivot coupled to the pick arm, and a plate coupled to the pivot via a pin and slot interface. In that example, a slot of the pin and slot interface is to adjust position of the pivot and adjust orientation of the pick arm.

    Abstract translation: 在一个示例中，介质馈送系统包括拾取臂，拾取臂可在枢轴处调节并且可操作以在拾取臂改变取向时维持拾取辊和分隔壁之间的距离。 在另一个示例中，介质馈送系统可以包括拾取臂，耦合到拾取臂的拾取辊，耦合到拾取臂的枢轴和经由销和槽接口耦合到枢轴的板。 在这个例子中，插针和插槽接口的插槽将调整枢轴的位置并调整拾音臂的方向。
