Abstract
Methods and systems for controlling and adjusting heat distribution over a part bed are disclosed. In one embodiment, a technique for providing a calibrated heat distribution over a part bed includes determining the temperature distribution within a part bed, generating a zone heat distribution for a plurality of heat zones from the temperature distribution, analyzing the zone heat distribution to create an adjustment command to calibrate a heater for providing a substantially consistent temperature distribution within the part bed, and adjusting the heater based on the adjustment command.
