摘要： There is provided a method and apparatus for controlling heat to a build surface. A thermal profile over the build surface is determined. The determined thermal profile over the build surface is compared with an expected thermal profile over the build surface. Based on the comparison, the determined thermal profile over the build surface or the expected thermal profile over the build surface is selected to control an amount of heat provided by a heating module to the build surface.

摘要： A three-dimensional object may be generated. A temperature sensor may be to measure a temperature distribution of build material delivered to a support member. A processor may be to mask a masking region of the measured temperature distribution or correct the measured temperature distribution, based on emissivity data of the build material. A heater may be to heat the build material to a target temperature distribution based on the corrected or masked measured temperature distribution. An energy source may be to apply energy to the build material to cause a portion of the build material to coalesce.
