First Claim
Patent Images
1. A system for generating a three-dimensional object, the system comprising:
- at least one sensor to detect temperatures of a current layer of build material on a support member, each of the temperatures corresponding to a respective area of the current layer; and
a controller to;
based on data representing the three-dimensional object, filter a subset of the temperatures from spatial temperature distribution data comprising the temperatures; and
control a degree of heat or energy applied to the current layer based on the filtered spatial temperature distribution data.

Abstract
Temperatures of a layer of build material on a support member may be detected. Each of the temperatures corresponding to a respective area of the layer. Based on data representing the three-dimensional object, a subset of the temperatures may be filtered from spatial temperature distribution data comprising the temperatures. A degree of heat or energy applied to the layer may be controlled based on the filtered spatial temperature distribution data.

14. A non-transitory computer readable storage medium including executable instructions that, when executed by a processor, cause the processor to:
-
obtain spatial temperature distribution data representing temperatures, each of the temperatures based on a respective measurement of a respective area of the layer of build material on a support member, the build material to be used for generating a three-dimensional object; interpolate the spatial distribution data; filter some of the temperatures from the interpolated spatial temperature distribution data using slice data representing a slice of the three-dimensional object; and control heat or energy applied to the layer using the filtered spatial distribution data.

15. A method comprising:
-
forming a layer of build material on a support member; measuring temperatures of a layer of build material on a support member, each of the temperatures corresponding to a respective area of the layer; and filtering part of the spatial temperature distribution data using data representing a three-dimensional object; and selectively depositing agent onto a portion of the layer of the build material; controlling heat or energy applied to the layer using the filtered spatial distribution data, wherein the heat is for heating the layer before depositing the agent, and the energy is for causing the portion to coalesce and solidify to form a slice of the three-dimensional object.
