Abstract
A method for additive manufacturing of a three-dimensional object () by successive, selective layer-by-layer solidification of layers of a construction material () by at least one energy beam, wherein the successive, selective solidification of the construction material () is carried out due to a data record describing the three-dimensional object to be additively manufactured (), wherein construction material sections provided for sintering and/or melting on or melting through are heated in a temperature range lying below the solidification temperature of the construction material (), wherein the heating of the construction material section(s) is carried out by at least one heating beam () either surrounding at least one main beam () provided for melting on or melting through in sections or going ahead or following the main beam (), wherein the main beam () and the heating beam () are together guided synchronously along the surface of the construction material ().
