Abstract: According to examples, a system may include a recoater and a controller. The controller may identify a structure of a surface of a layer of build material formed on a build platform and may determine whether the identified structure of the surface includes a portion that has a property that is outside of a predefined property level. Based on a determination that the portion has a property that is outside of the predefined property level, an adjustment to be applied to an operation of the recoater to achieve an intended structure of the layer and/or an intended structure of a subsequent layer may be determined and the determined adjustment on the operation of the recoater may be applied.

Abstract: According to one example, there is provided a 3D printing build unit comprising a build chamber, a build platform, and a heating element controllable to heat a portion of the contents of the build chamber to a temperature at or above a curing temperature whilst maintaining upper layers of the build chamber at or below a printing temperature.

Abstract: A printing method is disclosed, in which a fixing liquid is applied to a print medium both to first regions of the print medium that are to be printed and to second regions of the print medium that are not to be printed. A printing liquid is also applied to the print medium at the first regions of the print medium. The fixing liquid applied to the second regions of the print medium protects the second regions of the print medium from aerosol droplets generated when applying the printing liquid to the first regions of the print medium.

Abstract: A printing fluid circulation system is described. The system comprises first and second reservoirs, an outlet to supply printing fluid to a fluid inlet of a printhead, an inlet to receive printing fluid from a fluid outlet of the printhead, and a supply system. The supply system is to operate in a first mode to concurrently supply printing fluid from the first reservoir to the outlet and from the inlet to the second reservoir, and in a second mode to concurrently supply printing fluid from the second reservoir to the outlet and from the inlet to the first reservoir.
