Abstract
A method of manufacturing a three-dimensional object by selectively solidifying layers of a powdery material () at the locations corresponding to the cross-section of the object () in the respective layers by impact of electromagnetic radiation () is provided, where in a plastic powder, preferably polyamide, is used as powder, wherein the non-solidified powder (') is subjected to a treatment by water or water vapour at increased temperatures after manufacturing the object, subsequently dried and thereafter used again to build-up a new object.
