Abstract: Examples described herein relate to a method of 3D printing. In an example, at least part of a layer of build material is fused. The temperatures of the fused part of the layer are measured at different locations using respective temperature sensors. The temperature sensors are calibrated using the measured temperatures. Heating of additional layers of build material is controlled using the calibrated temperature sensors.

Abstract: Certain examples described herein relate to adjusting an energy source of a 3D printing system. In certain cases, a build bed of a 3D printing system is arranged to receive a layer of build material and the energy source of the 3D printing system is controllable to provide energy to a zone of the build bed. The energy provided by the energy source associated with the zone is adjusted based on a difference between a predetermined heat loss of the build bed and a determined heat loss for the zone, where individual adjustments of energy provided to at least some zones of the build bed collectively provide a uniform heat loss across the build bed.
