Abstract

The invention relates to a method for producing a three-dimensional workpiece. The method comprises irradiating a raw material layer with a laser beam, wherein a melt bath is produced at a point at which the laser beam impinges on the raw material layer, changing a position of the laser beam on the raw material layer with the aid of a first diverting unit and changing the position of the laser beam on the raw material layer with the aid of a second diverting unit. The second diverting unit is designed to divert the position of the laser beam with a greater acceleration than a maximum possible acceleration of a diversion by the first diverting unit. The invention also relates to a device for producing a three-dimensional workpiece.
