Abstract

Plant ( 1 ) for additively manufacturing of three-dimensional objects ( 2 ), comprising at least two apparatuses ( 3, 4 ) for additively manufacturing of three-dimensional objects ( 2 ) by means of successive layerwise selective irradiation and consolidation of layers of a build material ( 5 ) which can be consolidated by means of an energy beam ( 6 - 9 ), wherein a separate beam generating unit ( 10 ) configured to generate at least one energy beam ( 6 - 9 ) that is guidable to at least one of the apparatuses ( 3, 4 ).

First claim

The invention claimed is:

1. A plant for additively manufacturing three-dimensional objects, the plant comprising:
at least two apparatuses configured for additively manufacturing three-dimensional objects by successive layerwise selective irradiation and consolidation of layers of a build material in a respective build plane; and,
a separate beam generating unit configured to generate at least two energy beams that are guidable to at least two apparatuses, wherein the at least two energy beams comprise different beam properties being applied to the respective build planes, and wherein the different beam properties comprise different beam profiles.

2. The plant of claim 1 , further comprising a beam guiding unit configured to guide the at least two energy beams to the at least two apparatuses.

3. The plant of claim 2 further comprising a control unit configured to control the beam guiding unit based at least on an energy beam demand of at least one of the apparatuses.

4. The plant of claim 3 , wherein the energy beam demand comprises information relating to a process step of at least one apparatus and/or a status of a manufacturing process.

5. The plant of claim 1 further comprising at least one irradiation unit configured to irradiate at least one region of the object and/or a segment of at least one layer dependent on at least one beam property of at least two energy beams.

6. The plant of claim 1 , wherein the beam generating unit comprises at least two energy beam sources configured to generate the at least two energy beams, wherein the at least two energy beams comprise different beam properties.

7. The plant of claim 1 , wherein the different beam properties further comprise different wavelengths and/or power levels.

8. A method for operating a plant for additively manufacturing three-dimensional objects, the method comprising:
generating at least two energy beams from a separate beam generating unit, wherein the at least two energy beams comprise different beam properties being applied to respective build planes, and wherein the different beam properties comprise different beam profiles; and
guiding the at least two energy beams to at least two apparatuses for additively manufacturing of three-dimensional objects by successive layerwise selective irradiation and consolidation of layers of a build material in the respective build planes.

9. The method of claim 8 , wherein the at least two energy beams are selectively distributed between at least two apparatuses.

10. The method of claim 9 , where guiding the at least two energy beams comprises a control unit control controlling a beam guiding unit to selectively distribute the at least wo energy beams to the at least two apparatuses based at least on an energy beam demands of at least one of the apparatuses.

11. The method of claim 10 , wherein the energy beam demand comprises information relating to a process step of at least one apparatus and/or a status of a manufacturing process.

12. The method of claim 8 , wherein the at least two energy beams are selectively distributed between at least two apparatuses via a beam guiding unit.

13. The method of claim 8 further comprising:
irradiating at least one region of the object via an irradiation unit dependent on at least one beam property of at least one energy beam.

14. The plant of claim 8 , wherein the different beam properties further comprise different wavelengths and/or power levels.
