BUILD SURFACE HEAT CONTROL
First Claim
Patent Images
1. A method comprising:
- determining a thermal profile over a build surface;
comparing the determined thermal profile over the build surface with an expected thermal profile over the build surface; and
based on the comparison, selecting the determined thermal profile over the build surface or the expected thermal profile over the build surface to control an amount of heat provided by a heating module to the build surface.

Abstract
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.

12. An apparatus comprising:
-
a sensor module to obtain a thermal profile over a build surface; a processing module to compare the obtained thermal profile over the build surface with an expected thermal profile over the build surface; and a control module to control an amount of heat provided to the build surface by a heating module using the obtained thermal profile over the build surface or the expected thermal profile over the build surface, depending on a result of the comparison. - View Dependent Claims (13, 14)

15. A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising:
-
instructions to measure a thermal profile over a build surface; instructions to compare the measured thermal profile over the build surface with an expected thermal profile over the build surface; and instructions to, based on the comparison, select the measured thermal profile over the build surface or the expected thermal profile over the build surface to control heating of the build surface.
