Gemäß einer Ausführungsform umfasst eine Düse einen Auswurfbereich und einen Beschleunigungsbereich. Der Auswurfbereich ist ausgestaltet, um ein Pulver auszuwerfen. Der Beschleunigungsbereich ist ausgestaltet, um das Pulver herum zu kreisen, und ist ausgestaltet, um das Pulver so zu beschleunigen, dass das Pulver zu einer Öffnung transportiert wird. A nozzle includes an ejection section and an acceleration section. A powder is configured to be ejected from the ejection section. The acceleration section is configured to allow the powder to circle around and is configured to accelerate the powder in a peripheral direction of the powder that circles around so as to transport the powder to an opening.
