摘要: Examples of determining the temperature of a print zone in an additive manufacturing system are described. In one case, the additive manufacturing system comprises a print zone, a radiation source, an infra-red sensor and an ambient light sensor. The infra-red sensor is configured to measure the temperature of the print zone, and the ambient light sensor is configured to measure visible electromagnetic radiation. The additive manufacturing system comprises a temperature controller to compensate data from the infra-red sensor for infra-red radiation from the radiation source using data from the ambient light sensor.
