Example implementations relate to process capability procedures for additive manufacturing machines. One example implementation receives and prints two objects with corresponding process values for a set of process parameters within two build regions of the build volume. Measurements are made of each object comprising print parameters and a dataset comprising data representing the process values associated with the print parameters and data representing the second process values associated with the second print parameters is generated.

Print operation using plural sets of process values

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.

Build layer coverage analysis

A material management apparatus for an additive manufacturing system comprises a build material supply system to supply build material to a building area for building an object by additive manufacturing. The build material supply system includes a first build material supply unit to supply build material from a first side of a building area and a second build material supply unit to supply build material from a second side of the building area, the second side opposing the first side. The material management apparatus also includes a controller to control the build material supply system to vary an amount of build material to be supplied via the first build material supply unit based on a detected difference between a first amount of material available for supply via the first build material supply unit and a second amount of material available for supply via the second build material supply unit.

Build material management

According to one example there is provided an apparatus for supplying build material to a three-dimensional printing system. The apparatus comprises a rotatable vane.

Supplying build material

According to one aspect there is provided a three-dimensional printer. The printer comprises a controller to obtain data relating to a layer of a build model, to process non-empty layers according to a first operating mode and to process empty layers according to a second operating mode.

Conserving energy for empty 3D printing layers

A removable build module to connect to a host apparatus, may include a build platform to support an object-to-be-built, a drive unit to move the build platform, a memory to receive and store build parameters, and an interface circuit to communicate the build parameters to the host apparatus.

Removable 3D build module comprising a memory

In one embodiment, an option to restrict printing to a first print media source is presented to a user of a printer that is configured to access a plurality of print media sources. An instruction to restrict printing to the first print media source is received from the user. The printer is restricted from printing to the first print media source.
