Abstract: Printing stations to receive build units are disclosed. The printing stations may comprise a first wall comprising two fixed receiving ports to engage with two fixed mounting elements of the build units, respectively, and a second wall comprising a third fixed receiving port to engage with a third fixed mounting element of the build units, and a calibration receiving port to be coupled to a fourth fixed mounting element when the build unit is inserted into the printing station.

Abstract: According to one example there is provided a 3D printing system (300) comprising a build material measurement module (310) to determine a level of contraction of a solidified portion of a layer of build material. The system further comprises a controller (312) to determine if the determined level of contraction is within an acceptable range, and to modify one or multiple operating parameters of the printing system such that solidified portions of a subsequently processed layer of build material have a level of contraction within an acceptable range.

Abstract: A printer comprises a printing assembly for printing an image on a print media in a print zone; a cutting assembly for cutting the print media along a contour in a cut zone; wherein the print zone and the cut zone are distinct from one another, one of the zones being downstream of the respective other zone in a print media advance direction; a control unit controlling the printhead assembly and the cutting assembly to perform printing and cutting operations during a single print media feed. A method of printing, using said printer, comprises feeding the print media through the cut zone and through the print zone, in any order; and simultaneously printing an image and cutting a contour while the print media is being fed through the cut zone and through the print zone.

Abstract: In one example, an apparatus includes a carriage to carry a payload through a manufacturing space at the urging of control elements in a control space and a belt movable with the carriage to block contaminants in the manufacturing space from passing to the control space along a carriage travel path.

Abstract: In one example, an elevator for a roll of print media includes rotatable shafts oriented parallel to one another and translatable supports to support a roll of print media. Each support is operatively connected to the shafts such that rotating the shafts in a first direction raises the supports and rotating the shafts in a second direction opposite the first direction lowers the supports.

Abstract: In some examples, a printing system includes a printhead that is relatively moveable with respect to a print platform, and an airflow generator assembly to generate a first cooling airflow towards the printhead responsive to the printhead being at in a first inactive region on a first side of the print platform, and generate a second cooling airflow towards the printhead responsive to the printhead being in a second inactive region on a second, different side of the print platform.

Abstract: In an example, a method includes forming a layer of build material and selectively applying fusing agent on to the layer based on a predetermined pattern. Energy may be applied to the layer of build material, and at least one temperature of the layer may be measured. A temperature distribution over the layer of build material may be determined, the temperature distribution indicating, for each of a plurality of locations on the layer of build material, whether fusing agent is present at that location. At least one characteristic derived from the temperature distribution may be compared to a predetermined characteristic. When the compared characteristics differ, an operational characteristic of an additive manufacturing apparatus may be adjusted.
