摘要： Examples of the present disclosure relate to an additive manufacturing system. The system comprises a build material supply mechanism to deposit build material on a build surface. The system comprises a pre-heating system to apply globally pre-heating energy to pre-heat an upper layer of the deposited build material to a temperature below a fusing temperature of the build material. The system comprises a fusing system to selectively fuse deposited build material by locally heating the build material above the fusing temperature. The pre-heating system is to vary over time a spatial distribution of the applied pre-heating energy.

摘要： Examples of temperature measurement calibration in an additive manufacturing system are described. In one case, a method of calibrating a non-contact temperature measurement device involves applying energy from a radiation source of the additive manufacturing system to heat a reference element. The reference element is thermally coupled to a temperature sensor. A temperature reading from the temperature sensor is compared with data from the non-contact temperature measurement device to calibrate the device.
