Abstract: Method and devices for calibrating heat sensors are provided. The heat sensors may measure, from a distance, temperatures of build materials arranged on build platforms. Using the heat sensors, remote temperature measurements of regions may be acquired from a distance. Using temperature sensors integrated in the build platforms, local temperature measurements of regions of the build platforms may be acquired. The local temperature measurements may be compared with the remote temperature measurements to calculate differences. Correction factors associated with the calculated differences may then be applied when acquiring temperature measurements using the heat sensors.

Abstract: A method and system for causing an additive manufacturing system to print objects are described herein. A controller (110) of an additive manufacturing system (100) that comprises a build unit (120) and the controller (110) is arranged to receive print data defining an object to be printed by the additive manufacturing system (100). The controller (110) is arranged to cause the additive manufacturing system (100) to print a further object according to the modified print data, wherein the modified print data is determined on the basis of the print data.
