Process and device for producing a three-dimensional object

摘要

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 ).
