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, characterized by the step of controlled removal of non-solidified pulverulent material (11) after completing the object (3).
Claims8
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;
- cooling the object during removing of the non-solidified powder material, wherein the cooling is performed in a controlled manner;
- and
- raising the carrier during cooling.
