According to an example, a heating device comprises a plurality of light emitting arrays to emit a respective irradiance associated with a calibration profile and a power source electrically connected to the plurality of light emitting arrays, wherein the irradiances emitted by the plurality of light emitting arrays result in a substantially spatially uniform irradiance towards a target surface.

Heating devices for three-dimensional printers

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 of a method of operating an additive manufacturing system, a three-dimensional (3D) printing system and a non-transitory machine-readable medium are described. In an example, a build material is supplied to a print region of an additive manufacturing system. A temperature distribution, corresponding to a pattern, of at least a surface of the build material is generated. An image of the pattern is captured using a thermal sensor. Image data representative of the image of the pattern is compared with data representative of an expected position of the pattern. On the basis of the comparing, difference data indicative of a difference between a position of the thermal sensor during capture of the image and an expected position of the thermal sensor associated with the expected position of the pattern is generated. Operation of the additive manufacturing system is controlled at least in dependence on the difference data.
