Method for operating at least one apparatus () for additively manufacturing three-dimensional objects () by means of successive layerwise selective irradiation and consolidation of layers of a powdered build material () which can be consolidated by means of an energy beam (), whereby waste thermal energy (WTE) is generated during operation of the at least one apparatus (), characterized in that the waste thermal energy (WTE) is at least partly used for generating electrical or mechanical energy (EE, ME) by means of at least one energy converting device () and/or the waste thermal energy (WTE) is at least partly used for operating at least one thermal energy consuming device.

Method for operating at least one apparatus for additively manufacturing three-dimensional objects

A device () for the additive production of three-dimensional objects () by successive, layered, selective irradiation and accompanying successive, layered, selective solidification of construction material layers of a construction material () that can be solidified by means of an energy beam, comprising: a plurality of irradiation devices (and), which are designed to generate an energy beam, a control device (), which is designed to generate control information controlling the operation of the irradiation devices (and) and to control the operation of the irradiation devices (and) on the basis of generated control information, wherein the control device () is designed to generate first control information in order to control the operation of a first irradiation device, on the basis of which the first irradiation device generates a first energy beam () for the successive, layered, selective solidification of a construction material layer.

Device for additive production of three-dimensional objects

Irradiation device () for an apparatus () for additively manufacturing three-dimensional objects () by means of successive layerwise selective irradiation and consolidation of layers of a build material () which can be consolidated by means of an energy source, which Irradiation device () comprises at least one irradiation unit (-), preferably an optical unit, arranged in a housing () of the Irradiation device (), wherein a stream generating device () is provided that is adapted to guide a gas stream () that is adapted to be charged with residues present inside the housing () through the housing () of the Irradiation device () along a streaming path in which the gas stream () at least partially streams alongside or through the at least one irradiation unit (-) for removing residues from the housing ().

Irradiation device for an apparatus for additively manufacturing three-dimensional objects

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 ().
