Abstract: A heater may be to heat build material during a three-dimensional print job. A sensor may be to measure a temperature distribution of the build material. A processor may be to obtain first temperature data representing a first temperature distribution of build material associated with normal functioning of the heater. The processor may be to obtain second temperature data representing a second temperature distribution of the build material to be measured by the temperature sensor during the three-dimensional print job. The processor may be to compare the first temperature distribution to the second temperature distribution. The processor may be to determine whether the heater is malfunctioning based on the comparison.

Abstract: A controller for an additive manufacturing system comprises a processor to: receive data associated with a 3D printing job to generate at least one 3D object using one or more materials; determine, based on the received data, at least one operational parameter to be used by the additive manufacturing system in completing the 3D printing job; calculate, based on the received data, a value of at least one geometric parameter associated with the 3D printing job; and for at least one of the one or more materials, determine, based on the determined at least one operational parameter and the calculated value of the at least one geometric parameter, an amount of the at least one material to be used by the additive manufacturing system to complete the 3D printing job.

Abstract: A method of controlling a heating sub-system in an additive manufacturing system. The method comprising receiving thermal imaging information from a temperature sensing subsystem, receiving additive manufacturing media concentration information from an additive manufacturing media concentration information database, on the basis of the received thermal imaging information and additive manufacturing media concentration information, for each pixel area in the plurality of pixel areas, determining the temperature for each additive manufacturing media agent in the plurality of additive manufacturing media agents which is present in the respective pixel area, and on the basis of the determined temperatures for each pixel area and additive manufacturing media agent, controlling the power to a heating subsystem employed in the given additive manufacturing process.
