Abstract: In one example in accordance with the present disclosure, a fluid extraction system is described. The fluid extraction system includes an interface to fluidically and electrically couple a removable extraction reservoir to a printing device. The removable extraction reservoir is to receive an amount of fluid from a reservoir in the printing device. The system also includes a controller to, based on data received from memory of an interfaced removable extraction reservoir, initiate an extraction operation wherein fluid from the reservoir is passed to the removable extraction reservoir.

Abstract: An image file is prepared for printing. The image file is received. The image file includes a cell having pixels. A pixel of the pixels of the cell corresponds with a command to apply a print substance to a medium. For the pixel, the command to apply the print substance is selectively replaced with a command to not apply the print substance.

Abstract: Example tracking measures for a first functionality category may be used to generate a modified tracking measure if it is determined that the first functionality category is unsupported by an automated functionality tracking component. The modified tracking measure may be transmitted for categorization in a second functionality category, wherein the second functionality category is different from the first functionality category.

Abstract: A build material dispensing device may include a material spreader to spread an amount of build material along a build platform, and at least one hopper for dispensing the build material. The at least one hopper dispenses a plurality of doses of the build material in front of the progression of the material spreader as the material spreader is moved over the build platform.

Abstract: A control system for a three-dimensional printer includes an energy component interface, an agent depositing component interface, and control logic. The control logic controls the operation of an energy component through the energy component interface and an agent depositing component through the agent depositing component, in forming an output object that is specified in a print job. Additionally, in some examples, the control logic can implement a plurality of modes. Each mode, when selected modulate one or more operational parameters of a least one of the energy component or agent depositing component.

Abstract: A 3D printer and method include a cartridge receiver to hold a material cartridge that accepts build material into the material cartridge from the 3D printer and makes build material available from the material cartridge. A first conveying system of the 3D printer transports build material for the 3D printing. A second conveying system of the 3D printer facilitates recovery of excess build material from the 3D printing.

Abstract: In an example implementation, a method of printing a three-dimensional (3D) object includes scanning a print bar in a first direction over a build platform of a 3D printer to deposit a liquid agent onto a layer of build powder. The print bar is then indexed in a second direction substantially orthogonal to the first direction before scanning the print bar back over the build platform in a third direction opposite the first direction to deposit additional liquid agent onto the layer of build powder.

Abstract: The direction and distance for traversal by a media loaded into the printer is determined. A skew to be induced in a position of the media relative to a media feed direction axis is also determined. A scheme of motion for the rollers is selected and respective speeds for the first roller and the second roller are calculated. The first roller and the second roller are caused to be rotated at the respective speeds such that the skew is induced in the position of the media relative to the media feed direction.
