Abstract

Apparatus ( 1 ) for additively manufacturing of 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 apparatus ( 1 ) comprises a tool carrier device ( 2 ) adapted to position at least one tool unit ( 3 ) inside a process chamber ( 4 ) of the apparatus ( 1 ), wherein the tool carrier device ( 2 ) comprises at least one, in particular exchangeable, tool unit ( 3 ) that is moveable between a retracted position in which the tool unit ( 3 ) is received in a tool housing ( 6 ) enclosing the tool unit ( 3 ) and an extended position in which the tool unit ( 3 ) is at least partly extended from the tool housing ( 6 ).

Claims (29)

1. An apparatus for additively manufacturing three-dimensional objects, the apparatus comprising:

a process chamber;

a process chamber separation element, the process chamber separation element configured to separate the process chamber into a first process chamber region and a second process chamber region, wherein the first process chamber region comprises a process plane for additively manufacturing a three-dimensional object;

a tool housing moveable within the second process chamber region; and

a tool carrier device configured to position a tool unit carried by the tool carrier device inside the process chamber, wherein the tool carrier device is configured to be moveable between:

a retracted position wherein the tool unit is received in the tool housing; and

an extended position wherein the tool unit is at least partly extended from the tool housing,

wherein the tool unit comprises a coater blade configured to convey build material from a dose plane of a dose module to the build plane of the build module.

2. The apparatus of claim 1 , wherein the tool housing is moveable relative to the process chamber.

3. The apparatus of claim 1 , wherein the retracted position comprises the tool housing being sealed against an environment of the process chamber.

4. The apparatus of claim 1 , comprising:

a tool housing cover configured to seal the tool housing with the tool unit in the retracted position.

5. The apparatus of claim 1 , comprising:

a sealing unit configured to seal the first process chamber region from the second process chamber region, wherein the sealing unit is deformable and/or moveable in connection with a movement and/or a position of the tool carrier device and/or of the tool unit.

6. The apparatus of claim 5 , wherein the process chamber separation element comprises the sealing unit, wherein the sealing unit is arranged in a lower portion of the process chamber separation element, the lower portion of the process chamber separation element being located above the process plane.

7. The apparatus of claim 1 , wherein the tool unit comprises a plurality of exchangeable tools.

8. The apparatus of claim 1 , wherein the tool housing is linearly moveable along at least one process chamber wall.

9. The apparatus of claim 1 , wherein the tool housing cover is coupled to the tool unit.

10. A method of additively manufacturing a three-dimensional object, the method comprising:

separating, with a process chamber separation element, a process chamber of an apparatus for additively manufacturing three-dimensional objects into a first process chamber region and a second process chamber region, wherein the first process chamber region comprises a process plane for additively manufacturing a three-dimensional object; and

positioning a tool unit inside the process chamber, the tool unit being carried by a tool carrier device and the tool carrier device configured to position the tool unit, wherein positioning the tool unit comprises:

moving the tool carrier device, at least in part within the second process chamber region, between a retracted position and an extended position, the retracted position comprising the tool unit being received in a tool housing and the extended position comprising the tool unit being at least partly extended from the tool housing, wherein the tool unit comprises a coater blade configured to convey build material from a dose plane of a dose module to the build plane of the build module.

11. The method of claim 10 , comprising:

moving the tool carrier to the extended position, wherein moving the tool carrier to the extended position comprises locating the tool unit above a dose plane of a dose module; and

conveying build material from the dose plane to a build plane of a build module, wherein the tool unit comprises a coater blade configured to convey the build material.

12. The method of claim 10 , comprising:

moving the tool carrier from the retracted position to the extended position, wherein moving the tool carrier to the extended position comprises moving the tool housing into the process chamber.

13. The method of claim 10 , comprising:

moving the tool carrier from the extended position to the retracted position, wherein the tool unit being in the retracted position and received in the tool housing comprises the tool housing being sealed against an environment of the process chamber.
