Abstract: Examples include apparatuses, processes, and methods for generating three-dimensional objects. An example apparatus comprises build material distributor and a controller. Examples distribute a particular build layer in a build area of the apparatus over a previous build layer. Examples determine a build layer temperature corresponding to the particular build layer. Examples analyze build layer coverage for the particular build layer based at least in part on a build layer temperature of the previous build layer and the build layer temperature of the particular build layer. Examples selectively recoat the particular build layer with additional build material based at least in part on the build layer coverage for the particular build layer.

Abstract: According to one example, there is provided a method of determining characteristics of a build material. The method comprises obtaining a first quantity of a first build material, determining, for the first build material, the proportion of non-marked build material and marked build material, determining, based on the determined proportion, a first quantity of the first build material to be combined with a second quantity of a second build material to produce a third quantity of mixed build material having a predetermined proportion of marked build material.

Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurized gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurized gas.

Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurised gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurised gas.
