Abstract
A method of manufacturing 3D objects in an apparatus having a thermal sensor, a stationary heat source and one or more further heat sources. The method includes a warm up and a build process; each processing multiple layers by a layer cycle. The layer cycles include (a) providing build bed surface of particulate material; (b) heating the surface using the stationary or a first moving heat source; (b1) depositing absorption modifier (absorber) over one or more layer-specific regions and/or depositing absorption modifier (inhibitor) over a surrounding area; (c) heating the surface by the first or a second moving heat source; and (d) measuring the temperature of the surface after (a) and/or (b) and/or (c). During one or more of (a) to (c), heating the surface to a target temperature, such that (c) causes the layer-specific region of each layer to melt and form a portion of the 3D object.
