Device and method for the layered production of a three-dimensional object from a powdered constituent

Disclosed is a method in which a three-dimensional object is produced by successively compacting layers of a powdered constituent at the points corresponding to the cross-section of the object in the respective layer under the effect of a laser or another source of energy. The powdered constituent u...

More Information
Summary:Disclosed is a method in which a three-dimensional object is produced by successively compacting layers of a powdered constituent at the points corresponding to the cross-section of the object in the respective layer under the effect of a laser or another source of energy. The powdered constituent used in said method is a material containing old powder left over as non-compacted powder from the production of one or several previously created objects as well as some new powder never used before during a production process. The inventive method is characterized in that the powdered constituent is mechanically compacted when a layer is applied.
