Abstract
A method of manufacturing 3D objects with an apparatus having first and second heat sources and a thermal sensor. The method includes carrying out a build process after a thermal calibration process for a thermal control component(s). The calibration and build processes include a layer cycle including (i) providing a layer of particulate material defining a build bed surface; (ia) heating the surface; (ii) depositing absorption modifier over a layer-specific region and/or a surrounding area; (iii) heating the layer-specific region with the first heat source; and (iv) measuring a temperature of the surface after at least one of (i) to (iii). The layer cycle includes heating the surface of each layer with the second heat source and repeating until the calibration/build processes are complete. The outcome of each calibration routine being based on the measured temperature and being applied to the thermal control component for the subsequent layer cycle.
