Zusammenfassung:	The secondary circuit (10) has an overflow container (20) that is provided for receiving excess powder from a space (120) of the device (100). A return line (30) is provided for recycling of powder from the overflow container in a main circuit (110) of the device. An overflow pipe (22) is provided for transfer of powder from installation space into overflow container. A shutoff valve (24) is provided at overflow pipe. The overflow container is provided with level sensor (26). Independent claims are included for the following: (1) device for producing three-dimensional metal object; and (2) method for handling excess powder in device for producing three-dimensional metal object. Die vorliegende Erfindung betrifft einen Nebenkreislauf (10) für eine Vorrichtung (100) zur Herstellung dreidimensionaler metallischer Objekte, insbesondere für eine Strahlschmelzanlage, wobei zumindest einen Überlaufbehälter (20) für die Aufnahme von überschüssigem Pulver aus einem Bauraum (120) der Vorrichtung (100) und eine Rückführleitung (30) für die Rückführung von Pulver aus dem Überlaufbehälter (20) in einen Hauptkreislauf (110) der Vorrichtung (100).
