Abstract: An additive manufacturing system is described. The system includes a working area with a moveable platform, a supply mechanism to supply a build material to the working area, a radiation source to apply energy to the working area during construction of an object, so as to fuse at least a portion of the build material, a platform advance sensor to determine a displacement of the platform in at least a direction perpendicular to the plane of the platform, and a radiation source controller to adjust the energy applied by the radiation source based on the displacement measured by the platform advance sensor.
