Abstract: 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.

Abstract: An example device includes a camera to aim towards a build platform to receive material to be fused to form an article. The camera is to capture thermal images including a correction image captured during formation of the article at the build platform. The correction image is to be referenced to adjust a parameter of the formation of the article at the build platform. The example device further includes a controller connected to the camera. The controller is to control the camera to capture a calibration image with a heater associated with the build platform turned on. The controller is further to use the calibration image to compute a calibration to apply to the correction image.
