Abstract
A process is provided for producing a three-dimensional object having the steps forming the object (3) in a container (1, 200) arranged within a process chamber (100) on a carrier (4) which can be displaced in the container by sequential selective solidification of layers of a pulverulent material (11) which can be solidified by the action of electromagnetic or particle radiation at positions corresponding to the cross-section of the object in the particular layer, characterised by the step of controlled removal of non-solidified pulverulent material (11) after completing the object (3).
Claims41
A process for producing a three-dimensional object, the process comprising the steps of:
- providing a container arranged within a process chamber and a carrier that can be moved in the container;
- forming the object on the carrier in the container by sequential selective solidification of layers of a solidifiable powder material at positions corresponding to the cross-section of the object in the particular layer;
- and
- controlled removing of non-solidified powder material after forming the object to automatically unpack the object in a controlled manner without manual work.
A device for producing a three-dimensional object by sequential solidification of layers of a solidifiable powder material, the device comprising:
- a container for accommodating the object to be produced;
- a carrier that can be moved in the container;
- and
- an apparatus for controlled removal of non-solidified powder material after producing the object and automatically unpacking the object in a controlled manner without manual work.
A device for automatic unpacking and/or cooling of a three-dimensional object that is produced by sequential solidification of layers of a solidifiable powder material, the device comprising:
- a container for accommodating the object to be produced;
- a carrier that can be moved in the container;
- and
- an apparatus for controlled removal of non-solidified powder material after producing the object and automatically unpacking the object in a controlled manner without manual work.
A process for producing a three-dimensional object, the process comprising the steps of:
- providing a container arranged within a process chamber and a carrier that can be moved in the container;
- forming the object on the carrier in the container by sequential selective solidification of layers of a solidifiable powder material at positions corresponding to the cross-section of the object in the particular layer;
- controllably removing non-solidified powder material after forming the object by tilting the container at a predetermined angle to the vertical after forming the object.
A device;
- for producing a three-dimensional object by sequential solidification of layers of a solidifiable powder material, the device comprising:
- a container for accommodating the object to be produced;
- a carrier that can be moved in the container;
- and
- an apparatus for controlled removal of non-solidified powder material after producing the object,
- wherein the container has an upper rim and the device further comprises an overflow region curved outwards in region on the upper rim and means for tilting the container by a predetermined angle (A) to a vertical in the direction of the overflow device.
