Abstract
A method for the additive manufacturing of an object from a powder layer comprises the steps of: projecting () a beam of energy onto a surface of the layer of powder in the form of a spot so as to melt the powder, scanning () the surface with the beam of energy so that the spot travels over the surface in a movement made up of a translation in a longitudinal direction of scanning and of a wobbling movement having at least a component in a direction of wobble, and adjusting () the focus of the beam of energy during the scanning according to the translation in the longitudinal direction of scanning but without taking account of the component of the wobbling movement in the direction of wobble.
