Abstract
Described is a method for analyzing a build layer () in an additive manufacturing machine when forming a three-dimensional article layer by layer by successive fusion of selected areas of powder layers, which selected areas correspond to successive layers of the three-dimensional article. The method comprises the steps of radiating a portion () of the build layer () by an energy beam and detecting particles emitted, backscattered or reflected from the radiated portion of the build layer, and scanning the portion () of the build layer by moving the energy beam along a main path () and simultaneously moving the energy beam back-and-forth across the main path in a meandering pattern ().
