Abstract

A method of manufacturing a three-dimensional object is disclosed, in which the object is solidified layer by layer by solidifying a building material by means of a beam of a gas laser at locations in each layer corresponding to the cross section of the object, wherein the power of the laser is measured and the power of the laser is controlled according to the measured value. The power measurement takes place in a time window, in which a change of the power occurs, and an input control signal of the laser is controlled according to the measured values.
